Hello,
I use XamDataGrid (XDG) in my project. Many XDDG are in the TabItemEx.
I have a NullReferenceException in PresentationFramework when i set the sorted description of the XDG (XAML or in code behind). The exception is thrown when i close the app.
I use PRISM and MVVM pattern in my project
The stackTrace:

The behavior is strange....
Any suggestion would be appreciated. Thanks.
I attach a sample project to describe this behavior.

Hi Stefan,
thanks you for you reply.
I have logged this with development under ID: 144134 and I have also created a support ticket on your behalf: CAS-117801-T4K7L1 and have linked the development issue to it, so that you can get automatically updated, when a Service Release containing the fix is available for download. You can get the new version from our website’s “My IG”, “My Keys & Downloads” tags: https://ko.infragistics.com/Membership/Default.aspx?panel=Downloads#Downloads
You can also monitor the support ticket’s progress through the “My Support Activity” tag: https://ko.infragistics.com/Membership/MySupport.aspx
i still need help.
Thanks.
