Hello Claude,
Thank you for the question. Actually, the GridViewComboBoxColumn does not support adding items in design time, because the way it works is different compared to RadComboBox control. It inherits GridViewDataColumn and uses a combo box only as editor. Actually, the combo box editor is the element that handles the items but it is created on the first entering in edit mode, and it is not accessible in design time. Moreover, if you want your data in grid to be consistent you have to determine value and display member for ComboBox column which is not possible in the standard items editor.
Write me back if you have any additional questions.
Kind regards,
