Please send us more details on the concrete scenario you have with RadDataGrid as well as some sample snippets and steps to reproduce the exception. Currently it is not possible to find out what went wrong having just the error.

Sorry, I don't know the exact scenario. But I have that type of exception in the App Center.

We will need more details on the exact scenario you have, in order to reproduce the issue and research it further. 
The provided stack trace is not enough. As my colleague explained we will need snippets, steps to reproduce the issue, or if you can send us a sample project. 

No answers yet. Maybe you can help?
