Busy indicator for WCF async calls in Silverlight 4?

Question

Hi Guys,

I have a SL4 app consuming WCF services. The client make async call to the services, during this time I would like to show some sort information or busy indicator on the screen which tells the users that the app is doing something.

Now I am pretty sure SL4 has something like this, but I am drawing a blank....

Can someone please point me to the right direction?

Thanks,

Voodoo

You need an animation storyboard and then use code like this:

wcfProxyClass.DoMethodAsync()
loadingStoryboard.Begin();

Then in the Completed event handler

loadingStoryboard.End(); // not sure on this syntax
