Unhandled Exception when filtering columns

[Ryan]

Trying to use the Radgrid to do server-side data filtering.  

I'm binding a dataset to a RadGrid, and setting the AutoPostBackOnFilter='true' for each column.  Clicking on the filter button throws this unhandled exception.

I've tried setting EnableLinqExpressions="false"

Hello,

I tried to reproduce the unwanted behavior, but to no avail. Attached, you can find the project, which I used for testing. Could you review it and let me know what I am missing in replicating the issue? In case, you have some comments on this matter, please let me know about them in the support ticket, you have opened about the same issue.

Thank you in advance for your cooperation.

All the best,
Milena
