i want when user click on DeleteBox
delete that row.
Use RowCommand Event.
The RowCommand event is raised when a button is clicked in the GridView control. This enables you to provide an event-handling method that performs a custom routine whenever this event occurs.
Buttons within a GridView control can also invoke some of the built-in functionality of the control. To perform one of these operations, set the CommandName property of a button to one of the values in the following table.
<asp:gridview id="ContactsGridView"
datasourceid="ContactsSource"
allowpaging="true"
autogeneratecolumns="false"
onrowcommand="ContactsGridView_RowCommand"
runat="server">
<columns>
<asp:buttonfield buttontype="Link"
commandname="Delete"
text="Delete"/>
<asp:boundfield datafield="ContactID"
headertext="Contact ID"/>
<asp:boundfield datafield="FirstName"
headertext="First Name"/>
<asp:boundfield datafield="LastName"
headertext="Last Name"/>
</columns>
</asp:gridview>
Sub ContactsGridView_RowCommand(ByVal sender As Object, ByVal e As GridViewCommandEventArgs)
' If multiple buttons are used in a GridView control, use the
' CommandName property to determine which button was clicked.
If e.CommandName = "Delete" Then
' Convert the row index stored in the CommandArgument
' property to an Integer.
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
'Call you delete function here
End IF
End Sub**strong text**
