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

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:

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 .  Source code <%@ Page Language="C#" AutoEventWireup="true" CodeFile="fileupload_backcolor.aspx.cs" Inherits="fileupload_backcolor" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> Enter Alpha color : <asp:TextBox ID="TextBox1" runat="server" Width=&qu

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>

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. Source code <%@ Page Language="C#" AutoEventWireup="true" CodeFile="fileupload_backcolor.aspx.cs" Inherits="fileupload_backcolor" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> Enter Alpha color : <asp:TextBox ID="TextBox1" runat="server" Width="202px"><

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&q

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.

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 : Wind

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="serve

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” nod

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
