Hello Trey,
Thank you for writing.
I am glad that you have found a suitable solution for your specific case. However, note that when you programmatically add SortDescriptors, the SortChanging and SortChanged events are also fired. The SortChanging event is raised before the data is sorted. In the event handler the RadGridView.SortDescriptors collection is not updated yet as this is a cancelable event. If you need to clear the SortDescriptors collection, it is more suitable to use the SortChanged event when the sorting operation has already finished. Please refer to the following code snippet demonstrating how to manipulate the SortDescriptors collection avoiding an infinite loop and add programmatically a new SortDescriptor:
Feel free to modify the code snippet on a way to achieve the desired behavior.
I hope this information helps. Should you have further questions I would be glad to help.
Regards,
