    We have a tab control with a lot of children controls. As many others have experienced, there is a few second delay while the tab control loads the first time.

    I would like to give the user some sort of visual clue that work is being done during those few seconds. As it is now, the "dead-air" makes for a very bad user experience. I've tried every trick I can think of with the busy indicator (threading, set IsBusy=True in different events, etc) but can not get it to fire. I realize this is due to the UI thread being blocked.

    Is there any way to show the busy indicator or change the mouse pointer while a tab control is loading? I was hoping the speed improvements in Silverlight 5 would solve this problem but it has not.

    Thank you,

    Hi Brian ,

     We don't believe there is a way to use BusyIndicator to indicate that the controls in your RadTabItems are loading. You could use it when portions of data are loaded in GridViews, SheduleView for example , like demonstrated in this demo. But multiple UserControls loading among with animation processing ( the RadBusyindicator's animation) - we don't believe this is possible in Silverlight.
    However, this is more like a general SL question, not a "telerik controls specific" one, so I believe you could also search in other SL forums.

    Kind regards,
