If u want to add a check box in a Datagrid in Asp.Net applications. U select the datagrid in the webform and at bottom of properties window u r able to view property builder (Click it), then a dialog window will be opened. there u select columns and then in the column box select template column. the type a name for that column. click apply then close that window. now (right click) the datagrid and select edit template, there select the column name displayed bcoz it will display only the template column. then entire datagrid appearance will be changed. Now in the datagrid click the item template using mouse. the cursor blibks in that column. Go to the tool box double click any one of the control like(Check-Box). now it will be added to the item template. then right click the datagrid and (click) End Template u will be getting the grid to original appearance with Checkbox in the template column.

Here's a programatic example:

<asp:TemplateColumn HeaderText="myColumn" ItemStyle-Wrap="False">
           <asp:DropDownList ID="dropList1" Runat=server DataTextField="myText" DataValueField="table_identifier" DataSource='<%# GetSrc()%>' SelectedIndex='<%# GetSelIndex(Container.DataItem("myColumn"))%>' Enabled='<%# GetBool("myColumn")%>' OnSelectedIndexChanged="GetSelChanged" AutoPostBack=True/>

Define this at the top of your code:

Dim ds As DataSet = New DataSet

Function GetSrc() As DataSet

cnstr = ConfigurationSettings.AppSettings("myDBConnString")


Dim cn As New SqlConnection(cnstr)

sql = "SELECT table_identifier, mytext FROM myTable"

da As SqlDataAdapter

da = New SqlDataAdapter(sql, cn)

' fill dataset
da.Fill(ds, "myTable")

' Add null row to dataset.
Dim dt As DataTable = ds.Tables("myTable")

Dim NullRow As DataRow = dt.NewRow()
NullRow("table_identifier") = "0"
NullRow("myText") = "Select Something Here"
dt.Rows.InsertAt(NullRow, 0)

Return ds

End Function

Function GetSelIndex(ByVal iVal As Object) As Integer

' loop through dataset

Dim sVal As String = iVal.ToString
Dim iLoop As Integer
Dim dt As DataTable
dt = ds.Tables("myTable")

For iLoop = 0 To dt.Rows.Count - 1

If sVal = dt.Rows(iLoop)("table_identifier").ToString Then

  Return iLoop

End If

Next iLoop

End Function


Function GetBool()
' This function would contain code allowing you to disable the control if the user/entity did not have proper rights to use this control in the grid or change it.

End Function

Ok, I think Eric Moore's post may have been what I'm looking for, but I'm a total novice and need help understanding the code. I have added a template column to my data grid to hold a column of checkboxes. I cannot figure out, though, how to use the click event procedure to make the system recognize when the boxes are checked. Basically, I have a data grid representing the courses a college student is currently enrolled in. There is a column called "Drop" which is my template column that holds checkboxes. I want to allow the student to check mark the box(es) and hit a submit button. Then, I want the info from those boxes emailed to a particular person. My main problem right now is getting the code to recognize when the box is checked. Could someone help me in very basic terms?? :) Thanks so much!

you can use the same thing for different control:

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">


    <asp:BoundField DataField="" HeaderText="FirstName"/>

    <asp:BoundField DataField="" HeaderText="LastName" />

    <asp:TemplateField HeaderText="Gender">


        <asp:DropDownList ID="mytext" runat="server"></asp:DropDownList>
