    I have a grid with dynamic column.

    When i change the display column and then set sorting by code. An exception is appeared:

    Object reference not set to an instance of an object.
       at Telerik.Windows.Controls.InternalWindow.WindowWithNoChromeWindowHost.<>c__DisplayClass5.<Open>b__2()
       at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs)
       at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

    Hello Vo,

    We're not currently aware of such an issue and without being able to reproduce it at my end it's hard for me to suggest a possible cause for it.

    May I kindly ask you to open a new support ticket (as our system only allows images being attached in the forums) and send over a small sample project where the exception is isolated so that I can further assist you? Thank you in advance for your cooperation on the matter.

    Regards,
