Hi,
I encountered a problem while filtering or even performing Clear() on a collection that is binded to a GridView.

Steps to reproduce:
1. Loaded so many items to grid, that it show a scroll bar;
2. Scroll somewhere to the end of the list;
3. Apply a filter, that cuts let's say a half of the rows;
4. You should get a Visual Studio Just-In-Time Debugger Exception with message:
        System.IndexOutOfRangeException: Index was outside the bounds of the array.

The problem seems to occur also with your DataGridView->Performance example.
When selecting any of the last items, and applying the filter - everything disappears.

Thank for you help in advance,

Hi,
I've tried the online demo once again using both IE and Firefox. Steps I did:
1. Open the Grid -> Performance example
2. Scroll down the grid and click on the last element
3. Select filter on the Name column and select the first on the list
4. The result of above steps is in the attached file.

Below also the detailed message from the IE exception window (as not everthing is visible on the screenshot).

Exactly same error I got in my application. I got it also yesterday on the treeView control.
