On button Click in the Grid I can't get in to the function
===

Using CSharp, I'm not getting into the (GridView1_RowDeleting) function on the button click.. I don't know whats the problem is but wasted alot of time on it.


Default.aspx
                              
    asp:GridView ID="GridView1" runat="server" OnRowDeleting="GridView1_RowDeleting"
        AllowPaging="True">
        <Columns>
            <asp:TemplateField>
                <ItemTemplate>
                    <asp:ImageButton  ID="img1" runat="server" CommandName="GridView1_RowDeleting"  ImageUrl="~/Images/cross.png" />
                   
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>


Default.aspx.cs

     protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {

    }
