Adding a comboBox to a gridview in WinForms

Question

I am trying to create a gridview with a string column, a checkbox column, and a dropdownlist/combobox column. The first two are finished (all code behind), just need help with the last one.

DataTable dt = new DataTable("tblAir");
            dt.Columns.Add("Flight Details", typeof(string));
            dt.Columns.Add("Prefered Seating", typeof(bool));
            //doesn't work 
            dt.Columns.Add("Add Remark", typeof(ComboBox));

The data for the combobox is being supplied on load as we cannot work with a database.

Peter Bromberg has a detailed article on creating a Winforms gridview with comboboxes:
