<asp:UpdateProgress runat="server" AssociatedUpdatePanelID="UpdatePanel1" >  
  <ProgressTemplate>           
    <asp:Image ImageUrl="/images/progress.gif"/>
  </ProgressTemplate>
</asp:UpdateProgress>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
     //gridview, textbox and button controls            
</asp:UpdatePanel>

When testing this page on a local machine, the database tasks complete in a second. Maybe that's the reason the progress image doesnt show up. So I tried this..

btnSave_Click()
{
  System.Threading.Thread.Sleep(3000);
   //Code to save record to DB , bring back some data and bind to grid
}

Now, after clicking on btnSave, the image appears for 3 seconds and the DB task is done.

Here is the Question. When hosted on a server, the tasks might take 5-10 sec. So, in this case, will the image stay until the task is done or will it just stay for 3 secs, irrespective of the status of task.

I actually want to show the image until the tasks are done.

0	You code is perfect. It will show image until the server or db task is done. You can try to see your self. Just increase the System.Threading.Thread.Sleep(10000); to some more the it will show till the task finished. See the below example:- <body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1"> <ProgressTemplate> <asp:Image ImageUrl="/images/progress.gif" runat="server" /> </ProgressTemplate> </asp:UpdateProgress> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <asp:Button ID="btnSubmit" runat="server" Text="Submit" onclick="btnSubmit_Click" /> </ContentTemplate> </asp:UpdatePanel> </div> </form> </body> public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void btnSubmit_Click(object sender, EventArgs e) { System.Threading.Thread.Sleep(5000); } } Hope you understand.
