Hello Devel,

The scenario described in this item was not related to accessing properties of DependencyObjects in a background thread.

It was related to modifying an ObservableCollection that is bound to the ItemsSource of the RadGridView in a background thread which is allowed.

Pardon me, but manipulating properties bound to WPF UI Thread should be done only from WPF UI Thread. 

 

This is basics for WPF and Telerik controls should not do anything with the threading, because it can lead to side effects and undesired behaviour.
