I am handling the xamDataGrid1_CellChanged in my code behind. When the user changes a combo selection I check the value and I attempt to reset it to another value but the text displayed in the combo cell still displays the old value not matter what I try. The value gets changed but the grid displays the old value until the user enters edit mode again. I have tried all of the following.

xamDataGrid1.ExecuteCommand(Infragistics.Windows.DataPresenter.DataPresenterCommands.EndEditModeAndDiscardChanges);
            CellValuePresenter cvp = CellValuePresenter.FromCell(e.Cell);
           

            ValueEditor editor = cvp.Editor;
            if (!editor.IsInEditMode)
            {
                editor.StartEditMode();
                ((XamComboEditor)e.Editor).SelectedIndex = 0;
                editor.Value = e.Editor.OriginalValue;
                editor.EndEditMode(true, false);
                // e.Handled = true;
            }
