If your ComboBox column does not display values until you edit one of the values, check to make sure you populated the DataSource of the ComboBox before populating the DataSource of the Grid.
// BAD 
gridBindingSource.DataSource = _Repository.GetGridData(); 
comboBindingSource.DataSource = _Repository.GetComboData(); 
 
// GOOD 
comboBindingSource.DataSource = _Repository.GetComboData(); 
gridBindingSource.DataSource = _Repository.GetGridData();

Hi Jon Masters,

Please explain your issue in more details as I could not understand what is wrong. Currently, the GridViewComboBoxColumn can only be added manually, it has no default relation to the data source of RadGridView.
I am looking forward to your reply.

Best wishes,

My problem was that when I had my bindings in the wrong order, when the grid was initially displayed all the of values in the dropdown column where blank until I put my cursor into the column and changed one of the values and then the entire column of values suddenly appeared. 

Took me an hour to figure out what was going on, so I thought I'd put a posting here so that if any other dev made the same mistake that I did, they could more quickly diagnose the error and move along.  Think of it as an FYI.
