I've submitted the following already as a pre-sales question, but I really need support fast so I'm also submitting it to the users. Please let me know if anyone knows how to fix this bug, or if it's truly something with the Telerik GridView control.
Here's a link (http://1drv.ms/1hm6fJs) to my compressed solution on my OneDrive which I've shared. The following steps will cause the test program to crash.
1. Run the application.
2. Scroll to the right so the WorldSeriesWins column is visible.
3. Click the filter icon button and set the filter to be "> 27" in the pop-up window
4. Click the "Filter" button and all rows will disappear (as expected) and the grid will scroll the whole way back to the left.
The Filter pop-up windows will still be visible and at this point click the "Clear Filter" button which causes the application to crash.
The bug seems to occur if the column is not visible. If you were to scroll the scroll bar back to the right so the WorldSeriesWins col was visible and click the "Clear Filter" button it would not crash.
