Question

I have an UpdateProgress control, that shows as an overlay (using CSS) for all async events for an update panel. Now, for certain EXPAND/COLLAPSE row command events, i just dont want to show that updateprogress.

Is there a way?

<script type="text/javascript">
    var prm = Sys.WebForms.PageRequestManager.getInstance();
    prm.add_initializeRequest(InitializeRequest);

    function InitializeRequest(sender, args) {
        var updateProgress = $get('UpdateProgress1');
        var postBackElement = args.get_postBackElement();
        if (postBackElement.id == '<%= Button1.ClientID %>') {
            updateProgress.control._associatedUpdatePanelId = 'dummyId';
        }
        else{
            updateProgress.control._associatedUpdatePanelId = null;
        }
    }

</script>
