We're experiencing a rather difficult to reproduce issue with the RadGridView.
One of our users is working on a Windows 8 machine with the latest version of Silverlight. When performing a drop action in our application 9/10 times he encounters the exception listed below.
The drop action is rather basic, this is the scenario:
- There's an ObservableCollection<T> bound (two-way) to the RadGridView.
- There's a button in each row that triggers a command.
- The command executes Remove(T) on the ObservableCollection<T>.
We're still using version 2013.2.0724.1050 of the controls, however, as I mentioned reproducing the problem is next to impossible for us (the developers) so we see little point in upgrading to the latest version currently.
Has anyone ever came across this problem? Or has it maybe been fixed already in subsequent releases?
