Hi All

I have modal popup which is called inside the grid using Imagebutton.
The popup is called in the server side event imgView_OnCommand. but i get the popup twice.

XML

<asp:TemplateField HeaderText="Delete" ItemStyle-Width="12%" HeaderStyle-Width="12%">
                                    <ItemTemplate>
                                        <asp:ImageButton ID="imgDelete" runat="server" ImageUrl="~/Images/delete1.jpg" Width="20px"
                                            Height="20px" OnClick="imgDelete_Click" OnCommand="imgDelete_Command" CommandArgument='<%# Eval("UserId") %>'
                                            CommandName="DeleteUser" />
                                    </ItemTemplate>
                                    <HeaderStyle HorizontalAlign="Center" />
                                </asp:TemplateField>

There is no such event: imgView_OnCommand.

The fact you call this "event" is maybe the source of your confusion.

No wonder you deny you fire twice, but the facts show you do something twice. Maybe, this is not firing the event write but calling an event handler twice. It's relatively easy to resolve: put a break point inside the handler's body, run under debugger and examine the call stack. You will see where the redundant call came from.

You are firing the event twice.
The CommandName is being used by the grid to fire it's OnItemCommand event, while your ImageButton is firing the onClick handler as well, so if the same code is being executed for both events then you would get your popup twice.
