I get this error while trying to group a column in the RadGridView:
Layout cycle detected. Layout could not complete.
The RadGridView is bound to a QueryableDomainServiceCollectionView using MVVM and uses a RadDataPager to implement paging. We are using SL5 and RadControls from Q1 2012.
Dragging any column on to the group panel, groups the grid and the grouped section appears collapsed as expected. Expanding the grouped section works fine too. But when I try to collapse the grouped section again, this error occurs. Any assistance here would be greatly appreciated. Also, let me know if you need any additional information.
