'Declaration Public Property DropDownButtonDisplayStyle As ButtonDisplayStyle
public ButtonDisplayStyle DropDownButtonDisplayStyle {get; set;}
The column provides the ability to control whether the dropdown button is displayed.
When set to Always (default), the dropdown button is always displayed, as is the case with an intrinsic ComboBox control.
When set to Never, the dropdown button is never displayed. Note that this does not affect whether the list portion of the control can be displayed.
When set to OnMouseEnter, the dropdown button is displayed when the cursor passes into the boundaries of the cell, and hidden when it passes outside.
