Hello, I would like to enquire on a solution of the problem as per title.
To elaborate, let's have 2 column as example: Serial and Status, where Serial is a regular data column, while Status is a ComboBox column.
If I sort the GridView by Status column (clicking the Status header), and I tried to edit a Status cell, I will get NullReferenceException. Debugging shows that RadGridView.SelectedItem is null.
I have no problem with other scenarios, such as sorting by Status column and edit a Serial cell, or sorting by Serial column and edit a Status cell, or sorting by Serial column and edit a Serial cell.
Thanks a lot for your attention.
