DomainUpDown.UpButton Method

Definition

Displays the previous item in the collection.

public:
 override void UpButton();
public override void UpButton ();
override this.UpButton : unit -> unit
Public Overrides Sub UpButton ()

Remarks

As you move through the collection of items in the DomainUpDown control using the up button, you will eventually reach the first item in the collection. If you continue, and Wrap is set to true, the list will start over with the last item in the collection and appear to be continuous. This behavior also occurs when you move through the collection using the down button.
