Add column in WPF DataGrid using both xaml and code

Introduction

In this article i will show you how to add columns in DataGrid using xaml code and c# code. I will give you an example of add columns in WPF DataGrid. Datagrid is used to represent a tabular view of data in programming. It have multiple template designs to be customizable by the programmer as per the requirements. It supports some other features like sorting the data, dragging columns and sometimes editing when user needs to do.

To add a DataGrid, just drag-n-drop it from the toolbox. Now it is known as a tabular representation, write following code to add some columns (3 here):

<DataGrid>

<DataGrid.Columns>

<DataGridTextColumn Header="First Column"/>

<DataGridTextColumn Header="Second Column"/>

<DataGridTextColumn Header="Third Column"/>

</DataGrid.Columns>

</DataGrid>

When we run this window then a Datagrid is shown with three columns like in below image:

DataGrid provides columns sorting, reordering and sizing with some properties like CanUserReorderColumns, CanUserResizeColumns, CanUserSortColumns and etc. We can even perform grouping of data by adding a group description for the list to be bind.

To add a datagrid using code behind:

DataGrid dataGrid = new DataGrid();

DataGridTextColumn textColumn1 = new DataGridTextColumn();

textColumn1.Header = "First Column";

DataGridTextColumn textColumn2 = new DataGridTextColumn();

textColumn2.Header = "Second Column";

DataGridTextColumn textColumn3 = new DataGridTextColumn();

textColumn3.Header = "Third Column";

dataGrid.Columns.Add(textColumn1);

dataGrid.Columns.Add(textColumn2);

dataGrid.Columns.Add(textColumn3);

The above code snippet add a same datagrid with three columns as in above image. We will learn binding of datagrid in later articles.

Edit menu bar with cut copy and paste operations in Windows Form C#

Introduction

In this article i will show you how to do cut copy and paste operation on text which is entered in the TextBox. I will give you an example of it. It is impossible for one, specially a Programmer, to imagine his/her life without editing. Editing operations (Cut/Copy and paste etc.) are performed using clipboard, so these are also called Clipboard operation.

Invention

Larry Tesler, who invented Cut/Copy and paste in 1973. He is a computer scientist, working in the field of human-computer interaction. Tesler has worked at Xerox PARC, Apple Computer, Amazon.com and Yahoo! We can find out more about LarryTesler.

In this article I will show how to perform these operations with our own code. As we are just doing editing operations, it doesn't matter which control we are using. Here I am using two textboxes to perform this operation. I created a simple window form with a menu strip and two textboxes. In the menu strip all the operations are added in Edit menu item as shown in below screenshot.

Generate the click event of above three menu items. 

Copy

We are going to copy the selected text of textbox, so we use SelectedText property of textbox. To copy the data in clipboard there is a method in Clipboard class i.e. SetData(), which will clear the clipboard and then add new data in specified format to clipboard.

private void copyToolStripMenuItem_Click(object sender, EventArgs e)

{

      TextBox txtBox = this.ActiveControl as TextBox;

      if (txtBox.SelectedText != string.Empty)

         Clipboard.SetData(DataFormats.Text, txtBox.SelectedText);

} 

Cut

Actually, cut operation is a combination of copying and removing that text from that location. So we will copy the text and empty that string after that.

private void cutToolStripMenuItem_Click(object sender, EventArgs e)

{

    TextBox txtBox = this.ActiveControl as TextBox;

    if (txtBox.SelectedText != string.Empty)

       Clipboard.SetData(DataFormats.Text, txtBox.SelectedText);

    txtBox.SelectedText = string.Empty;

} 

Paste

To insert clipboard data to current location is called paste. We can perform a paste operation multiple times with a single clipboard data. To paste the data from clipboard there is a method in Clipboard class i.e. GetText(). First we get actual position of cursor in the textbox and then insert the data to that position using Insert() method as in above code.

private void pasteToolStripMenuItem_Click(object sender, EventArgs e)

{

    int position = ((TextBox)this.ActiveControl).SelectionStart;

    this.ActiveControl.Text = this.ActiveControl.Text.Insert(position, Clipboard.GetText());

}

Insert() is a method of string class, which return a string in which a specified string is inserted at a specified position. So that is how we perform editing operations with our own code. The same procedure can be used to perform these operation in other controls of windows forms.

Bind CheckBoxList from Database in ASP.Net C# Example

Introduction:

In this article we will learn how to bind CheckBoxList in asp.net c#. I will give you an example of CheckBoxlist binding. you can use a CheckBoxList control to display a number of check boxes at once as a column of check boxes. The CheckBoxList control exists within the System.Web.UI.WebControls namespace. This control is often useful when you want to bind the data from a datasource to checkboxes . The CheckBoxList control creates multiselection checkbox groups at runtime by binding these controls to a data source.

Public Properties of the CheckBoxList class

Cellpadding : Obtains the distance between the border and data of the cell in pixels.

CellSpacing : Obtains the distance between cells in pixels.

RepeatColumns : Obtains the number of columns to display in the CheckBoxList control.

RepeatDirection : Obtain a value that indicate , whether the control displays vertically or horizontally.

RepeatLayout : Obtains the layout of the check boxes.

TextAlign : Obtains the text placement for the check boxes within the group.

STEP-1 :  Create Database Table  in visual studio 2012.

STEP-2 :   Select CheckBoxList from ToolBox and drop onto Design window

STEP-3 : Bind CheckBoxList on PageLoad method.

                            da.Fill(ds);

                            CheckBoxList1.DataSource = ds;

                            CheckBoxList1.DataTextField = "name";

                            CheckBoxList1.DataValueField = "Employeeid";

                            CheckBoxList1.DataBind();
