ArgumentOutOfRangeException sometimes when grouping and sorting columns

[Mat]

This is quite hard to reproduce, but by clicking around on the column headers to group and sort them quickly enough I can generate an exception similar to this:

System.ArgumentOutOfRangeException was unhandled
  Message=Index must be within the bounds of the List.
Parameter name: index
  Source=mscorlib
  ParamName=index

  InnerException:

I've made a small example project with a simple grid and can reproduce it there as well
(I can't see how I can attach it to this thread?)

The grid simply has 5 columns and 5000 rows

All I do is rapidly drag any column header into the grouping bar, remove it and change the sorting on it by clicking round like a mad man! It's quite random and sometimes takes as much as a minute to reproduce

Here's the XAML in case it helps:

If anyone has any suggestions as to how I can improve the scrolling speed as well I'd be very grateful!

Hello,

Can you post more info about your grid version? Please remove temporary this setting and let me know how it goes:
<Setter Property="DataLoadMode" Value="Asynchronous" /> 

Best wishes,
Vlad

Telerik.Windows.Controls.GridView version 2011.1.315.35

I can still reproduce when using Asynchronous DataLoadMode

Is there no way I can upload my example project to this post?

Hello Mat,

You could possibly upload the application on a third party site and then send us the link to the zip file.

Greetings,

I have the same bug when trying to drag column header into the grouping bar (see screenshot). Telerik.Windows.Controls.GridView version 2011.1.0419.35

Do you have any updates for this issue?
