I am working on RadTreeListView which comes with default sorting on Control Column. I have a requirement to disable the default on RadTreeListView and enable the custom sorting on RadTreeListView. I had used the CollectionViewSource and also subscribed to OnSorting event handle and able to sort the binded item source. But view is not getting refreshed.
Using Comparer to sort the items in the itemsource and MVVM pattern.
Even thought binded item source is sorted as expected, the UI is not getting refreshed with expected sorted view. The control is getting sorted using the default control sorting mechanism.
