How to do busy indicator

[DonFreeman]

Most of the Silverlight apps I have seen provide a busy indicator of some type while the map is loading. This is usually a sequence of circles like a chase light with percent complete in the center. I thought this was maybe a default Silverlight thing, but although my map takes a while to load, there is no indication anything is happening. So, how do I turn on or create this feature?
Thanks

I think you need to customize the existing ProgressBar control. http://msdn.microsoft.com/en-us/library/dd334413(VS.95).aspx. You can also check out SL Toolkit here: http://www.silverlight.net/content/samples/sl4/toolkitcontrolsamples/run/default.html.

As for map loading that shows progress bar or busy indicator, this is related thread: http://forums.arcgis.com/threads/23519-Issue-with-LayerCollection-LayersInitialized-event.
