You can convert you control to pages and can load them Asynchronously with javascript easily. You can also use loading images for more effective UI.

Hi:)

Without seeing your codes, It's very hard for me to tell...

I think if you've got so many data to load with your Custom Controls, maybe you can use something like AJAX's Update Panel or JQuery's Ajax technology to deal with your problem.

Maybe you can create an ascx Customized control, put a ScriptManger as well as an Update Panel there, and throw your other things together inside, and with an UpdataProgressBar. When the data is loading, it will fetch data from db or something else, which can let you wait for a while.

Thx

About more UpdateProgress with UpdatePanel, please refer to this: http://www.codeproject.com/KB/ajax/UpdateProgress.aspx

Something codes like this:

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
  </ContentTemplate>
</asp:UpdatePanel>
<asp:UpdateProgress ID="UpdateProgress1"
     AssociatedUpdatePanelID="UpdatePanel1" runat="server">
<ProgressTemplate>Update in Progress…….. </ProgressTemplate>       <!--Well, you can put explaination words as well as flash image to show the progress for loading……-->
</asp:UpdateProgress>

Hi,

You can create handler files(.ashx) also. See this http://forums.asp.net/t/1166701.aspx/1

You can call them asynchronously using simple jquery call $.get(). See this http://api.jquery.com/jQuery.get/
