public string SourceName { get; set; }

member this.SourceName : string with get, set

Public Property SourceName As String

Property Value

String

The default value is null. If this property value is null, then the element being monitored for the raising of the event is the templated parent or the logical tree root.

Exceptions

InvalidOperationException

Remarks

You can set this property to the name of any element within the scope of where the trigger collection (the collection that this EventTrigger is part of) is applied. This is typically a named element that is within the template that contains this EventTrigger. If you are setting the Triggers property on an element directly, then it is a named element within the scope of that parent element.

You can name an object using the x:Name Directive syntax.
