Assembly: System.Windows (in System.Windows.dll)
public delegate void DependencyPropertyChangedEventHandler( Object sender, DependencyPropertyChangedEventArgs e )
This delegate is the handler signature for particular events that report dependency property changes. One event in Silverlight that uses this delegate is IsEnabledChanged.
An event that uses this handler is exposed as a common language runtime (CLR) event, not as a routed event. Typically these events follow the naming pattern IsPropertyNameChanged, where PropertyName is the name of the property that changed. The event data of the event is used to query the old and new value of the property, as reported by the particular event occurence. Typically there is a direct correspondence between properties that change and a particular event that reports the change. It is also possible, though uncommon, to have the same event report changes to more than one property. In this case, DependencyPropertyChangedEventArgs as reported by e should be checked to determine the property that changed.
