There's an exception that occurs with the UXGridView when dealing with a UXGridViewExpanderColumn and BusyIndicator (both the Silverlight Toolkit BusyIndicator and UXBusyIndicator behave the same way) when binding to a items source. Taking away either component seems to make the exception go away, which is an unacceptable solution as I need to have busy indicator in place and would like an UXGridView with row details. The exception occurance also seems very finicky as using a different data source seems to make it behave better (also unacceptable).

It probably took me 3-4 hours to figure out the source of this bug, and another 2-3 hours to create a an app in its simpliest form to re-create the exception so you could see it. The sample app I created is here (only dependency it has is Silverlight 4 Toolkit and Client UI v5):

In the above app there's a "Submit" button, the exception occurs on the second submit. Thanks for looking into this.

The exception that occurs is :

Cannot resolve TargetName StylishLabel.
