I wan't to set this.Cursor = Cursor.Wait in the SelectionChanged event of a DataGrid, then when a (sometimes lengthy) process of loading the RowDetails is finished, set this.Cursor = Cursor.Arrow.
Problem is that the LoadingRowDetails event is only called the first time the row is loaded.
So I have 2 questions:
1. How can I know if LoadingRowDetails will be called or not?
2. Why does is take so long to load the row details if I put the a DataGrid inside of an Expander (see XAML below)?
