I'm populating the combo box items in the GetEditorType event which has worked fine up until now.
In that event I clear the combobox items, then add in the required ones.
I just tried setting ControlLook.DropDownAlwaysVisible true for the same grid, but now the downdown list contains 2 sets of those items.
If I populate the combo list in the FormCreate event the list is correct. Any ideas?
