Inheritance

System.Object

DomainUpDown

Namespace: Syncfusion.Windows.Shared

Assembly: Syncfusion.Shared.Wpf.dll

Syntax

public class DomainUpDown : Control

Remarks

Represents an up-down control that displays string values.

A DomainUpDown control displays a single string value that is selected from the collection of items by pressing the up or down buttons on keyboard or scrolling the mouse wheel. The user can also enter text in the control.

To create a collection of items to display in the DomainUpDown control, user can add or remove the items individually by using the Add(String) and Remove(String) methods. This can be called in an event handler, such as the DomainUpDown event of a button.
