Best "Loading" feedback for ASP.Net?

So, we have an ASP.Net application - fairly standard - and in there are lots of updatepanels, and postbacks.

On some pages we have 

<ajax:UpdatePanelAnimationExtender ID="ae" runat="server" TargetControlID="updatePanel" BehaviorID="UpdateAnimation">
    <Animations>
        <OnUpdating>
            <FadeOut Duration="0.1" minimumOpacity=".3"  />
        </OnUpdating>
        <OnUpdated>
            <FadeIn minimumOpacity=".5" Duration="0" />
        </OnUpdated>
    </Animations>
</ajax:UpdatePanelAnimationExtender>

Which basically whites out the page when a postback is going on (but this clashes with modal dialog grey backgrounds). In some cases we have a progressupdate control which just has a spinny icon in the middle of the page.

But none of them seem particularly nice and all a bit clunky. They also require a lot of code in various places around the app.

What methods do other people use and find effective?

Solution

  • Like the others, I suggest to use the UpdateProgress in a modal popup.

    I will add this twist, put the popup, UpdateProgress and this code in a masterpage, so whenever you need it, just plug the masterpage to the content page.

     <script type="text/javascript">
 var ModalProgress ='<%= ModalProgress.ClientID %>';
  Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(beginReq); 
  Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endReq);    
  function beginReq(sender, args){     
  // shows the Popup     
  $find(ModalProgress).show();        
  }  
  function endReq(sender, args) 
  {     
  //  hide the Popup     
  $find(ModalProgress).hide(); 
  }

</script>
