Why UpdateProgress Not Showing?

In the following scenarios, the UpdateProgress control will not display automatically:

The UpdateProgress control is associated with a specific update panel, but the asynchronous postback results from a control that is not inside that update panel.

The UpdateProgress control is not associated with any UpdatePanel control, and the asynchronous postback does not result from a control that is not inside an UpdatePanel and is not a trigger. For example, the update is performed in code.

For making the ajax update progress to be working in the above senarion, follow as descibed below.

Underneath the "asp:ScriptManager" element, add the following script:
<script language="javascript" type="text/javascript"> <!-- var prm = Sys.WebForms.PageRequestManager.getInstance(); prm.add_initializeRequest(InitializeRequest); prm.add_endRequest(EndRequest); var postBackElement; function InitializeRequest(sender, args) { if (prm.get_isInAsyncPostBack()) { args.set_cancel(true); } postBackElement = args.get_postBackElement(); if (postBackElement.id == 'Button1') { $get('UpdateProgress1').style.display = 'block'; } } function EndRequest(sender, args) { if (postBackElement.id == 'Button1') { $get('UpdateProgress1').style.display = 'none'; } } // --> </script>
Replace 'UpdateProgress1' with your Udateprogressbar id and replace 'Button1' with your trigering control id.
