Hello,
I am trying to work with the RadGridView and implement the external filter example in your How To section. I have been getting this error that I cannot seem to figure out. It happens when I type in the search to box and it occurs with a column header click event. At first I thought it had to do with saving and loading the state of the grid, but now I am not so sure. The error is being thrown in the CustomFilterDescription Class on the property FilterValue() and on the line:
Me.OnPropertyChanged("FilterValue")
Here is the error I am getting with the search for. (any suggestions would be appreciated)

I believe I have solved my own issue. The LINQ Expression was trying to evaluate the type on an anonymous typed collection. It couldn't determine the type and that is when it crashed. By adding "ToList" the the query returned solved my problem.
