I would think this would be fairly straightforward but can't seem to find a solution. I need to intercept the GridViewGroupRow_Loaded event and change the header text based on some condition. Style selectors, Converters, and Header Templates are not able to achieve what i want. Also, the example using EventSetter does not work in Silverlight. Where and how can i get the GridViewGroupRow_Loaded event to fire? thx.
