I have a RadGridView that can be loaded with various different business objects, primarily containing double, int and string members for editing. The columns of some of these objects can be sorted, but on others, no column in the grid will sort. This is despite setting CanUserSortColumns and IsSortable to true. Strangely, grouping and filtering works on these objects. I have removed any custom CellTemplates in case that was the issue.
To figure this out, I attempted to listen to the Sorting event on the grid, but it never fires. Any hint as to what direction I should look? How does the RadGrid determine whether data can be sorted, aside from the xaml input?
