I am using a RadGridView where the ItemsSource is bound to a QueryableCollectionView that contains a RadObservableCollection of data. The data is loaded asynchronously from a web service, so on return from the service, the collection is updated by calling Clear, then AddRange, and then Refresh is called on the QueryableCollectionView.
This was working great until we applied the hotfix from 9/27 which we needed to fix another issue in the rich text editor. Once we applied the hotfix, the grid would not display any data in the rows, but would recognize the correct amount of data rows. The grid also does not display any filter buttons in the headers, and there is no change to the header state when sort is applied. I can see my data in the collection, but the grid won't display the cell contents.
This is also not working in the 9/20 build, but works fine in the 7/12 build and previous.
I cannot reproduce the problem by making synchronous calls to load data. This only happens when the Refresh is applied after a callback.
Thanks for any help.
Edit: Any columns where we override CreateCellElement are working. GridViewDataColumn without the override is not working.
