RadWindow show error

[Anooshiravan]

Hi

To create a modal popup in my aspx page I have put a RadWindow in the page like this:

    <telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
          <script src="scripts.js" type="text/javascript"></script>
          <link href="styles.css" rel="stylesheet" />
          <telerik:RadWindow RenderMode="Lightweight" ID="modalPopup" runat="server" Width="360px" Height="365px" Modal="true"                           OffsetElementID="main" Style="z-index: 100001;">
          <ContentTemplate>
               <div style="padding: 10px; text-align: center;">
               </div>
               <p style="text-align: center;">
                   RadWindow
               </p>
          </ContentTemplate>
    </telerik:RadWindow>

and inside the scripts.js file I have this code:

function showDialogInitially() {
    var wnd = $find("main_Content_Placeholder_modalPopup");
    wnd.show();
    Sys.Application.remove_load(showDialogInitially);
}
Sys.Application.add_load(showDialogInitially);

which works perfectly. but if I use this code instead:

    var wnd = $find("main_Content_Placeholder_modalPopup");
    wnd.show();

and put it at the end of the aspx file it won't show the window anymore.

so I suspect that has to do with the methods .add_load() and .remove_load() but I don't event know what they do.

can see what's going wrong?
