    When an iFrame is used to load RadWindow content, the status bar shows a loading indicator until the content is displayed. Is there any way to manually show this GIF in the for custom operations... like an AJAX transaction? There are times I auto-load data at intervals and don't want to lock down the entire RadWindow, but I do want a nice common place to show some operation is going on (and the status bar seems like a great place to do this). Any help would be appreciated.

    You can get a reference to the RadWindow from the page inside and call its _onWindowUrlChanging() and _onWindowUrlChanged() to show and hide the loading sign. If a full postback occurs the iframe's load event will fire and the loading sign will hide automatically. Otherwise you would need to hide it with your own code. You can find attached a simple example that uses buttons, in your actual case you should use the appropriate events (e.g. the PageRequestManager's beginRequest and endRequest).
