Hi, all.

I have the next problem:

1. Load GridView and data
2. Click on column filter
3. Click on check box "Select All"
4. Click on check box "Select All" again
and got this exception and application crashes
   о System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)
   о System.Collections.Generic.List`1.Enumerator.MoveNextRare()
   о System.Collections.Generic.List`1.Enumerator.MoveNext()
   о Telerik.Windows.Data.EnumerableExtensions.ElementAt(IEnumerable source, Int32 index)
   о Telerik.Windows.Data.QueryableCollectionView.InternalGetItemAt(Int32 index)
   о Telerik.Windows.Data.QueryableCollectionView.GetItemAt(Int32 index)
   о Telerik.Windows.Data.DataItemCollection.get_Item(Int32 index)
   о Telerik.Windows.Controls.GridView.GridViewItemContainerGenerator.Generator.GenerateNext(Boolean stopAtRealized, Boolean& isNewlyRealized)
   о Telerik.Windows.Controls.GridView.GridViewItemContainerGenerator.System.Windows.Controls.Primitives.IItemContainerGenerator.GenerateNext(Boolean& isNewlyRealized)
   о Telerik.Windows.Controls.GridView.GridViewVirtualizingPanel.MeasureOverride(Size constraint)
   о System.Windows.FrameworkElement.MeasureOverride(IntPtr nativeTarget, Single inWidth, Single inHeight, Single& outWidth, Single& outHeight)

please see screenshots

P.S. But in other cases filter works fine

And another one important question:
why the radgrid becames busy after RowEditEnded ??

Many thanks for the help.

Hello Vyacheslav Diliger,

That is weird.

Can you please attach a sample project that reproduces both this exception and the busy grid after RowEditEnded? We will debug it to see what is going on.

Thanks in advance.
