What do you mean by IsBusy can't be updated from the ViewModel? Do you mean that when you set it the View doesn't change? Is this because you are doing some resource intesive work on the UI thread? If that is the case what you want to do is use a BackgroundWorker to do your actually work. Here is a good article on it. You can then set the IsBusy property and it will show up in your view because the long running code will be on the worker thread.

If you have a ViewModel i would bind the IsBusy to a respective property, then you just need to change that.

e.g.

<extToolkit:BusyIndicator IsBusy="{Binding IsProcessing}" />
