i not try use editable combobox.  have done in 1 of projects , difficult use.  wouldn't recommend editing text box in datagridview.  better bind comboxboxes , text boxes in dgv regular text boxes , comboboxes.  dgv designed view data , not edit data.  better make form 1 textboxes/comboboxes each column of dgv.  user selected row of dgv automatically fill individual textboxes/comboboxes.  have button when user modified textboxes/comboboxes dgv gets updated.
