this is a code snippet:

ASP.NET

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4"
                                        DataSourceID="ObjectDataSource1" ForeColor="#333333" GridLines="None" meta:resourcekey="GridView1Resource1"
                                        OnSelectedIndexChanged="GridView1_SelectedIndexChanged" OnRowEditing="GridView1_RowUpdating">
                                        <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
                                        <!-- some columns-->
<ItemTemplate>
                                                    <asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="False" CommandName="Edit"
                                                        Text="Delete" meta:resourcekey="BoundFieldResource144"></asp:LinkButton>
                                                </ItemTemplate>
                                            </asp:TemplateField>
<!--user control-->
   <uc5:MessageBoxConfirm  runat="server" ID="MessageBoxCon"   ButtonNoText="No" ButtonYesText="Yes" />

the code behinde:

C#

protected void GridView1_RowDeleting(object sender, GridViewEditEventArgs e)
  {
      try
      {

        MessageBoxCon.ShowBox(CommonRes.Delete,CommonRes.AreYouSureThatYouWantToDelete, CommonRes.Yes, CommonRes.No);//user control

                 int count = Convert.ToInt32(e.NewEditIndex);
          List<classname> clrList = new List<classname>();
          clsList = (List<classname>)Session["SaveList"];

          classname clsnm = new classname();
          clsnm  = clrList.ElementAt(count);

          clsList.Remove(clsnm );
          Session["SaveList"] = clsList;

      }
      catch (Exception ex)
      {

      }

First of all, you have not defined the event in Markup.

Refer - GridView.RowDeleting Event[^]. See how it is defined in the example.

HTML

<asp:GridView ID="CustomersGridView" runat="server"
        DataSourceID="CustomersSqlDataSource"
        AutoGenerateColumns="False"
        AutoGenerateDeleteButton="True"
        OnRowDeleting="CustomersGridView_RowDeleting"
        DataKeyNames="CustomerID,AddressID">

And here it automatically shows Delete button, as a result of that, the event gets fired automatically when you click on that.

But if you want to use LinkButton, then you need to implement differently either with

RowCommand Event (example - http://www.codeproject.com/Articles/12666/GridView-Delete-with-Confirmation)

OR

LinkButton Click Event (example - Delete Row from Gridview using Link Button Click in Asp.net with Confirmation[^])
