RadGridView ItemsSource being updated in ViewModel (Using Dispatch) but Grid is still not updating.

[J.W.]

I'm using MVVM and I'm trying to show a grid that has an ItemsSource of an IList<object>. THe IList object does ... eventually ... empoly a base model that uses INotifyPropertyChanged so any change SHOULD be bubbling to the surface.

This IList is updated and modified in the ViewModel and I guessed it was on a different Thread, after some research, so I tried using the Dispatcher in order to have it trigger any updates. But still nothign in the GUI is changing.

The list is updating async but then the Grid is never showing the changes. 

Any ideas would be greatly appreciated.

Hello Jon McKInley,

I have prepared a sample project following the MVVM pattern, but I could not reproduce the mentioned behavior. The data grid gets updated, as well as the collection inside the ViewModel.

That said, I have attached the mentioned project, so could you edit it to match the behavior present on your side?

Hi Stenly, same answer as in the ticket. Had a bug way down deep of one of the async methods. Figured it out so TY very much!
