Answer 1

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**
