Property Value

If you change the AutoCompleteSource property to a value which does not equal System.Windows.Forms.AutoCompleteSource.ListItems, when the AutoCompleteMode property is not System.Windows.Forms.AutoCompleteMode.None, the ComboBoxCell changes DropDownStyle to MultiRowComboBoxStyle.DropDown automatically.
