Hello, I am getting the following exception when using grouping in RadGridView. The problem is that the exception seems to happen not inside my code, 
but entirely inside Telerik RadGridView control, so I cannot catch the exception. Any tips how to catch this exception or better - avoid the exception from occuring?  I using the Telerik version 2016.1.217.40. My twitter handle is @Tore_Aurstad. Nice if you got any tips, we are closing in on our release date for our client which is using the Telerik WPF library heavily. 

Thanks,

 Telerik.Windows.Controls.GridView.GridViewDataControl.NestedLayoutStrategy.GenerateScrollingStack

StackTrace:
   ved Telerik.Windows.Data.FuncExtensions.<>c__DisplayClass1`2.<ToUntypedFunc>b__0(Object item)
   ved Telerik.Windows.Controls.GridView.GridViewDataControl.NestedLayoutStrategy.GenerateScrollingStack(Object dataItem)
   ved Telerik.Windows.Controls.GridView.GridViewDataControl.NestedLayoutStrategy.ScrollRowIntoView(Object dataItem, Action`1 scrollFinishedCallback, Action scrollFailedCallback)
   ved Telerik.Windows.Controls.GridView.GridViewDataControl.ScrollRowIntoViewInternal(Object dataItem, Action`1 scrollFinishedCallback, Action scrollFailedCallback)

Hello,

Generally, it would be great if you can isolate the problem in a sample project. In this way, we will be able to debug it on our side. Please check this blog post for a reference.

As a workaround, you can try setting RadGridView's GroupRenderMode to Flat.

Hello, thanks for the help. We have to render the groups in the RadGridView as non-flat as we think the look and feel is too flat. Sadly, the solution I am working on is a bit too complex and large to find out how we can extract a sample project. I have at least reported to you an exception I have found, but for now I do not see a solution. Thanks for the help, anyways. Telerik controls are beautiful and great -  mostly of the time :)

Hi,

Actually the GroupRenderMode.Flat does not affect the look and feel of RadGridView's groups. It represents our new virtualization mechanism with a completely new item container generator. You can check this help article for a reference.
