Assembly : DevExpress.Xpf.Core.v25.2.dll

Declaration

C#
VB.NET

csharp

public class ItemMultiTrigger :
    ItemTriggerBase

Public Class ItemMultiTrigger
    Inherits ItemTriggerBase

Remarks

The ItemMultiTrigger allows you to set property values based on a condition collection. A condition is met when the ItemTriggerCondition.Value is equal to the ItemTriggerCondition.Property value or data returned by the ItemTriggerCondition.Binding.

The following code sample sets the BarButtonItem‘s Foreground to Red when the BarButtonItem is located in the MainMenu and the view model’s HighlightItemsInMenu property is true:
