WPF menu bar with dockpanel | additem | Image | Icon | Checkbox | Click event

In this article, I will teach you, how to add WPF menu bar at top position in window, Add items in it, add image as icon in it, also handle click event on each items of it. I explained, how to add items with underline.

<Window x:Class="WpfApplication5.MainWindow"  

     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  

     <DockPanel>  
Title="MainWindow" Height="350" Width="525">  
   <Grid>  
       <Menu DockPanel.Dock="Top">  

           <MenuItem Header=" second child"/>  
<MenuItem Header="_First Parent">  
           <MenuItem Header="New" Command="New"/>  

             </MenuItem.Icon>  
<MenuItem Header="Third child with image">  
             <MenuItem.Icon>  
               <Image Source="mango.png"/>  

           <MenuItem Header="Second first child" IsCheckable="True" IsChecked="True" Click="MenuItem_Click"/>  
</MenuItem>  
         </MenuItem>  
         <MenuItem Header="Second Parent">  
         </MenuItem>  
       </Menu>  
     </DockPanel>  

 </Window>  

   </Grid>  

The above-mentioned XAML code define, a menu control inside in DockPanel control at top position. The first item in the menu works as container. In the first menu item, we have three child items. First child item contains shortcut key by using command attribute. Second child item appears as simple text, last item contain image. Similarly add another menu item in the menu control for making second parent item with click event. 

  private void MenuItem_Click(object sender, RoutedEventArgs e)  
     {  
       MessageBox.Show("second parent first child clicked");  
     }  

When, I press child item of second parent item then appear a message box on the screen.
Code generates the following output:

Example of Login form in WPF

Today, I will teach you, how to design login form in WPF. Also, I will teach you, how it will work. In this example, I will take two text boxes, two Text Blocks and one button control from ToolBox. Now, create a database table with some following fields:

 CREATE TABLE [dbo].[users] (  
   [Id]    INT      NOT NULL IDENTITY,  
   [username] NVARCHAR (50) NULL,  
   [password] NVARCHAR (50) NULL,  
   PRIMARY KEY CLUSTERED ([Id] ASC)  
 );  

In this database table, I have three column, first column is automatic incremented by one.

 <Window x:Class="WpfApplication5.additemwpflistview"  
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
     Title="additemwpflistview" Height="300" Width="300">  
   <Grid>  
     <TextBlock HorizontalAlignment="Left" Margin="10,41,0,0" TextWrapping="Wrap" Text="UserName" VerticalAlignment="Top"/>  
     <TextBox Name="t1" HorizontalAlignment="Left" Height="23" Margin="94,41,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="120"/>  
     <TextBlock HorizontalAlignment="Left" Margin="15,91,0,0" TextWrapping="Wrap" Text="Password" VerticalAlignment="Top"/>  
     <TextBox Name="t2" HorizontalAlignment="Left" Height="23" Margin="94,84,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="120"/>  
     <Button Content="Login" HorizontalAlignment="Left" Margin="94,130,0,0" VerticalAlignment="Top" Width="75" Click="Button_Click"/>  
   </Grid>  
 </Window>  

Note: Before doing all such things, must to add EDMX file in the project.

  private void Button_Click(object sender, RoutedEventArgs e)  
     {  
       DatabaseEntities dbe = new DatabaseEntities();  
       if(t1.Text!= string.Empty || t2.Text!=string.Empty)  
       {  
         var users = dbe.users.FirstOrDefault(a => a.username.Equals(t1.Text));  
         if(users!=null)  
         {  
           if(users.password.Equals(t2.Text))  
           {  
             WPFListview l1 = new WPFListview();  
             l1.ShowDialog();  
           }  
         }  
       }  
     }  

Code generates the following output:

WPF Listview formatting, styling

In this article, I will teach you, how to change Background color, foreground color, font style, and many more things. I explained already many more things about WPF Listview like

1. How to add items in it using XAML code
2. How to bind the WPF Listview.view from Gridview.
3. WPF Listview binding from EDMX file 
4. Binding it with List of string type.

Also covered many more articles, which is related to styling and formatting. You can see my video article for Learn WPF styling using static as well as dynamic. Today, I will put some styles in XAML code. Let's see

   <ListView Name="list1" HorizontalAlignment="Left" VerticalAlignment="Top">  
       <ListViewItem FontFamily="Times New Roman" FontSize="15" Foreground="Red" Background="Green" BorderBrush="AliceBlue" BorderThickness="2">Apple</ListViewItem>  
       <ListViewItem FontSize="16" Foreground="Green" Background="orange" BorderBrush="AliceBlue" BorderThickness="2">Orange</ListViewItem>  
       <ListViewItem FontSize="17" Foreground="Red" Background="White" BorderBrush="AliceBlue" BorderThickness="2">Pea</ListViewItem>  
       <ListBoxItem>  
         </ListBoxItem>  
     </ListView>  

Code generates the following output

WPF Listview with ItemTemplate binding using EDMX file

In this article, I will teach you, how to bind WPF Listview with ItemTemplate using EDMX file. Also, I will give you an example of it. So far we have discussed basics of WPF Listview control. Let's see, what's are covered about WPF:

1. WPF Listview binding with Gridview cell template using EDMX file
2. WPF LISTVIEW BINDING USING EDMX FILE
3. wpf listview bind with list of string type

Let's see the example of this example:

 <Window x:Class="WpfApplication5.MainWindow"  
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
     Title="MainWindow" Height="350" Width="525">  
   <Grid>  
     <ListView Name="list1">  
       <ListView.ItemTemplate>  
         <DataTemplate>  
           <WrapPanel>  
             <TextBlock Text="Id="/>  
             <TextBlock Text="{Binding Id}"/>  
             <TextBlock Text=","/>  
             <TextBlock Text="Name="/>  
             <TextBlock Text="{Binding Emp_Name}"/>  
           </WrapPanel>  
         </DataTemplate>  
       </ListView.ItemTemplate>  
     </ListView>  
   </Grid>  
 </Window>  

Before doing code in code-behind file, add EDMX file in project.

  public partial class MainWindow : Window  
   {  
     public MainWindow()  
     {  
       InitializeComponent();  
       loaditemTemplate();  
     }  
     private void loaditemTemplate()  
     {  
       DatabaseEntities dbe = new DatabaseEntities();  
       list1.ItemsSource = dbe.Employees.ToList();  
     }  
   }  

Code generates the following output

First 3 WPF videos, start your learning

I will give you a WPF videos series. If you watch each then you do start your career with WPF. Through WPF videos, you can design light weight application. Let's start step by step. In first video you learn about basics of WPF projects, let's see

In this video, I will teach you many more things about WPF start like

1. How to start Visual Studio for WPF application.
2. Create new project for WPF, select C# language in left pane, select WPF application in middle pane.
3. First-page name of the default window is MainWindow.xaml. It contains default WPF Grid control.
4. Add a TextBlock with Text property inside WPF grid.
5. Learn, How to run WPF application.

Now, come to next video of WPF videos series. First of all, I will teach you about WPF panels. So, here, I share you a video of stack panel.

Check it, what is inside. Drag WPF stack panel control from ToolBox, drop it in Window. When we add it in Window then XAML automatically update with stack panel code. Here, we have HorizontalAlignment=left, Height="100", width="100", verticalAlignement="Top".  You can resize it by all corners using design window. Now, you can add buttons and other controls inside stack panel. A button control has content property, which is used as a label. By using orientation property, we can set controls alignment either horizontally and vertically. By using this video also, I explain you, how to add image in stack panel. Stack panel contains another stack panel. Now, come to next video of WPF videos series.

Grid panel is also a container. It has two things that are RowDefinition and ColumnDefinition. WPF grid is the most popular control in presentation foundation. By using this, we can add controls in it a specific cell  of Rows and columns. If, your controls are outside from grid then you can place it in WPF Grid, watch this video and learn, how to place control inside WPF Grid.

WPF Listview items with images

WPF ListView is a container of other single controls. I mean to say that you can put other single control in it. Other controls considered as a Listview item. You can put only simple single string or control like TextBlock. Lets to check the demo of this line.

1:     <ListView>  
2:        <ListViewItem>  
3:          <TextBlock Text="Fruits"/>  
4:        </ListViewItem>  
5:        <ListViewItem>  
6:          Vegetables  
7:        </ListViewItem>  
8:      </ListView>  

In this code, we have both string as well control. You can take other containers in it like StackPanel etc. as a ListView Item. In previous example, i taken Gridview control as view of Listview. Now, i will take image with Text in it as a single WPF Listview item.

1:  <ListView>  
2:        <ListViewItem>  
3:          <StackPanel Orientation="Horizontal">  
4:            <Image Source="apple.png"/>  
5:            <TextBlock Text="Apple"/>  
6:          </StackPanel>         
7:        </ListViewItem>  
8:        <ListViewItem>  
9:          <StackPanel Orientation="Horizontal">  
10:            <Image Source="mango.png"/>  
11:            <TextBlock Text="mango"/>  
12:          </StackPanel>  
13:        </ListViewItem>  
14:        <ListViewItem>  
15:          <StackPanel Orientation="Horizontal">  
16:            <Image Source="grapes.png"/>  
17:            <TextBlock Text="grapes"/>  
18:          </StackPanel>  
19:        </ListViewItem>  
20:      </ListView>  

Copy this code and paste into your WPF window, before doing this, please add three image into your project,. These three images names are apple.png, mango.png and grapes.png.

ASP.NET FILEUPLOAD CONTROL CHANGE BACKGROUND COLOR USING CODE

Each control in ASP.NET ToolBox of visual studio, treat as a class. Property window shows the behavior of their controls also contains some common property, such as back-color, border color etc. Now in this article, we will take a simple example to change the background color of ASP.NET file upload control.

Description
I explained, ASP.NET FILEUPLOAD CONTROL change border color, File upload control enable/disable.

Code Behind Code

 using System;  
 using System.Collections.Generic;  
 using System.Linq;  
 using System.Web;  
 using System.Web.UI;  
 using System.Web.UI.WebControls;  
 public partial class fileupload_backcolor : System.Web.UI.Page

     int blue = int.Parse(TextBox4.Text);  
     FileUpload1.BackColor = System.Drawing.Color.FromArgb(alpha, red, green, blue);  
   }  
 }  

Code Generate the following output

In this example, we are taking four textboxes, one button, one file upload control. Using text box we can input the color code value and pass these values into the FromArgb ( ) method. This example is basically designed for users, who want to change the color of file upload control at run time.

WPF Listview binding with Gridview cell template using EDMX file

Good evening, welcome to WPF programming. I already explained, how to bind WPF listview from string type list also explained binding it with database table using EDMX file. In this article, I will give you an example of cell template of Gridview, which is inside in WPF Listview. You can say, I will update previous WPF listview article. If you want to customize your Gridview cell in WPF Listview control then use cell template.

Note: Before doing this task, read previous

You need to change only XAML file without any changes in code behind code. The previous XAML code is:

<Grid>   

    <ListView Name="listgrid">   
<ListView.View>  

<GridView>  

       <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>  

       <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Emp_Name}"/>   
</GridView>       
     </ListView.View>     
    </ListView>   

   </Grid>   

Now, replace it with below-mentioned code

<Grid>  

     <ListView Name="listgrid">  
<ListView.View>

 <GridView> 

           <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>   

             <GridViewColumn Header="Name">  

<GridViewColumn.CellTemplate> 

                 <DataTemplate>  

<TextBlock Text="{Binding Emp_Name}" FontWeight="Bold"/>  
</DataTemplate> 

</GridViewColumn.CellTemplate> 

           </GridViewColumn>    
</GridView>          
       </ListView.View>     

   </Grid>  

     </ListView>  

Now, codes generate the following output:

ASP.NET fileupload control change border color Programmatically

Each control in tools of visual studio, treat as a class. Property window shows the behavior of their controls also contains some common property, such as back-color, border color etc. Now in this article, we will take a simple example to change the border color with border style of ASP.NET FILEUPLOAD control. I explained, How to use file upload, enable/disable file upload and many more properties.

     int green = int.Parse(TextBox3.Text);  
     int blue = int.Parse(TextBox4.Text);  
     FileUpload1.BorderColor = System.Drawing.Color.FromArgb(alpha, red, green, blue);  
     FileUpload1.BorderStyle = BorderStyle.Solid;  
     FileUpload1.BorderWidth = 2;  
   }  
 }  

Code Generates the following output

In this example, we are taking four textboxes, one button, one file upload control. Using text box we can input the color code value, pass these values in the FromArgb ( ) method as an argument. This example is basically designed for users, who want to change the border color of ASP.NET FILEUPLOAD control at run time.

ASP.NET Fileupload control enable/disable programmatically

Enable property defines the working mode of asp.net file upload control. It has two boolean value first one is true and second one is false. If you set true for this then control work properly otherwise control doesn't work, I mean to say that fileupload appear on screen but will not work as input control. If you want to set this property during compile time, must add attribute inside the tag. Like

Read Also: ASP.NET FILEUPLOAD CONTROL INSERT IMAGE IN DATABASE

  <asp:FileUpload ID="FileUpload1" runat="server" Enabled="False" />  

    true is the default value for this. Now take a simple example to change the value at run time.

Source code

 <form id="form1" runat="server">  
  <div>  
     <asp:FileUpload ID="FileUpload1" runat="server" Enabled="False" />  
     <br />  
     <br />  
     <asp:Button ID="Button1" runat="server" Text="Enable/Disable" OnClick="Button1_Click" />  
     <br />  
     <br />  
     <asp:Label ID="Label1" runat="server" Text=""></asp:Label>  
   </div>  
   </form>  

Code Behind 

 <script runat="server">  
   protected void Button1_Click(object sender, EventArgs e)  
   {  
     if (FileUpload1.Enabled == true)  
     {  

Label1.Text = "file upload control is enabled "; 

     
       FileUpload1.Enabled =  false;  
     }  
     else  
     {  
            Label1.Text = "file upload control is disabled ";

       FileUpload1.Enabled = true;  
     }  
   }  
 </script>  

Code Generate the following output

When we press the browse button then we know that it is working or not. Above mentioned snap define this. In first, snap you can see that open file dialog doesn't appear but in second snap its appear, so in second, snap it is working.

Default Listing with Insert and Update in MVC 4

MVC 4 provides simple listing procedure through which developer can create CRUD actions for a database table. Awesome thing is developer don’t need to write a single line of code and will complete the task.

We have added new table Category and updated edmx file in earlier article. Now we will create CRUD actions and their views with default MVC 4 structure. We have created empty controller without using any default action but now we will add a controller with all the default actions.

Follow the procedure for creating a controller and in “Add Controller” window name the controller as CategoryController and select the options as selected in the following screenshot and click on Add button:

This window is prompting for your context class (inherited from DbContext or may be your edmx entities name) file and the model name for which these actions will be created.

After clicking on Add button, it will add a controller with following 5 actions and corresponding views. Those views are not created on the root, but MVC 4 will create those views under new folder with the same name as controller.

• Create
• Delete
• Detail
• Edit
• Index

Run your project and go to specified controller/Index page, it will load all the categories your database have. Have a look on the below screenshot, with three records each having three action-link i.e. Edit, Details and Delete. Beside these individual action links this table structure also have Create New action on the top through which it will redirect to another view.

So we have saved lot of time that may waste to write the code for all these actions and also for creating their views. This MVC 4 feature is very simple to use and we can create more control for each table. Developer can customize these actions or their views as per their requirements.

Some developer don’t need all these views or maybe they want to enable all these actions on the single page. In next article we will create listing page for our own and write some line of code for table structure.

WPF LISTVIEW BINDING USING EDMX FILE

In previous WPF listview article, I explained, how to bind listview from List of string type. In this article, I will explain you, how to bind listview using EDMX file. We all know about powerful features of  WPF listview i.e Gridview. Lets, take an example of it.

  <Grid>  
     <ListView Name="listgrid">  
       <ListView.View>  
         <GridView>  
           <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>  
           <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Emp_Name}"/>  
         </GridView>          
       </ListView.View>     
     </ListView>  
   </Grid>  

In the mentioned code, Gridview is a view of WPF Listview with two columns that are Id and name. Here, DisplayMemberBinding is the property of GridviewColumn, which is used to bind listview columns from field of model class.

  public partial class MainWindow : Window  
   {  
     public MainWindow()  
     {  
       InitializeComponent();  
       loadlistview();  
     }  
     private void loadlistview()  
     {  
       DatabaseEntities dbe = new DatabaseEntities();  
       listgrid.ItemsSource = dbe.Employees.ToList();  
     }  
   }  

Here, DatabaseEntities, context class in EDMX model, also Employees is the public property in DataContext class. Learn How to add EDMX file with database file.
Now, code generate the following output:

ASP.NET FILEUPLOAD CONTROL INSERT IMAGE INTO DATABASE

Introduction

First of all, I would like to thank all of the readers who have read my previous articles. What a great support I have got from you people. By using ASP.NET File upload control, we can easily insert images into Table or you can say that we can create image gallery projects. With the help of JQuery, we put some dynamic effects like upload multiple files one by one. you can also do by JQuery to create button work as File upload. I really felt great when article Bind GridView was displayed on this blog page. Following are the articles that I have written so far for beginners as well as developers.

Follow some steps for inserting Images into database using asp.net fileupload control.

STEP-1 : Create Database Table

STEP-2: Drag asp.net fileupload control from ToolBox and Drop it in Design window.

  <form id="form1" runat="server">  
   <div>  
     <asp:FileUpload ID="FileUpload1" runat="server" /><BR />  
     <asp:Button ID="Button1" runat="server" Text="Submit" />

Update Edmx When Database Changes in MVC 4

MVC 4: Update Edmx is to make the model as same as the database through which it created. Whatever changes made with the database will not reflect in the Model to perform CURD functions. Suppose we have added a new table with SQL server management studio and want to insert/update some entries with that table using code part. After creating object of database context, notice that we don’t have an instance for that newly added table. To resolve this issue we have to update our edmx using Update Model Wizard as described in this article.

Create new table Category in the same database added earlier and use basic columns like id, name, description, isActive. Open our visual studio project and check that this table have not any existence yet. Open edmx file, right click on the blank space and click on Update Model from Database.

  An Update Model wizard will open with options to add tables, views and stored procedures. We have added only a table so expand “Tables” node and select “Categories”. Leave remaining options as they are and click finish.

 After finishing it will reload and will add newly added table, check the edmx file and there are two tables Employee and Categories as shown in below image.

This update model wizard does following in MVC 4:

• If a table removed from database, it will remove from the model also and update mapping details.
• If table has been added, it will insert new object in the existing model and update mapping details.
• Any modification in the object, this wizard will update the model like to add/remove columns.

Refactoring in visual studio 2013,2015

Refactoring, change the internal structure of the code without any changes in behavior/outer structure. By using visual studio plugins, you can do the following refactoring in the visual studio code. The most popular and powerful refactoring plugin/extension in visual studio is visual assist. By using it, we can do some following tasks:

• Extract method refactoring: By using visual studio we can create new methods for existing code, I want to say that if you have a code in a method, you want to break it in different segments/methods then you can use extract method like Suppose your code look like

   public class Class1  
   {  
     public void display()  
     {  
       int a=10;  
       int b=20;  
       Console.WriteLine(a + b);  
     }  
   }  

Select the code fragment you want to extract:

  int a=10;  
       int b=20;   

Right click on selected text, Refactor--> Extract Method..., appear new window.

After pressing the "ok" button, your code look like

  public class Class1  
   {  
     public void display()  
     {  
       int a;  
       int b;  
       NewMethod(out a, out b);  
       Console.WriteLine(Convert.ToString(a+b));  
     }  
     private static void NewMethod(out int a, out int b)  
     {  
       a = 10;  
       b = 20;  
     }  
   }  

• Change class name also the file name: If you want to change class name after creating code then you can do this by replacing. But, file name doesn't change. So, try visual assist to change the class name, constructor name, and file name.    

Right click on class name, select Refactor(VA)--Rename to change the class name also file name.

After do this, your code and file:

If you want to design web forms in asp.net then you need to learn some basic technologies like HTML, CSS, Photoshop, JQuery etc. Here, i will tech you about these technologies one by one using some web forms article. so, lets start, Following these steps to design beautiful we forms:

wpf listview bind with list of string type

As we all know the wpf listview is inherited class of listbox and have almost all the properties of listbox. We have learnt listbox binding with string list in our earlier post. In this article we bind the listview with the same string list.

Just place a wpf listview having only name property, because we have to access that wpf listview in our code behind file. We can also use height and width property of the listview, if the data items are of lengthy string.

<ListView>
<ListView.Name>listView</ListView.Name>
</ListView>

Now use the same list of string as in previous post i.e.

List<string> strList = new List<string>();
strList.Add("London");
strList.Add("Italy");
strList.Add("California");
strList.Add("France");
listView.ItemsSource = strList;

Now look out the last statement, it will set the item source of the wpf listview as this string list. When we run the project it will show a listview with four items:

To get selected item the same procedure will follow as in listview bind with grid resource.
