Syntax

   RoutedPropertyChangedEventArgs<Point> e
)
'Declaration
 
Protected Overridable Sub OnStartChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Point) _
) 
'Usage
 
Dim instance As AnnLineObject
Dim e As RoutedPropertyChangedEventArgs(Of Point)
 
instance.OnStartChanged(e)

            

            
protected:
virtual void OnStartChanged( 
   RoutedPropertyChangedEventArgs<Point>^ e
) 

Parameters

e
A RoutedPropertyChangedEventArgs that contains the event data.
Remarks

Raising an event invokes the event handler through a delegate.

The OnStartChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors: When overriding OnStartChanged in a derived class, be sure to call the base class's OnStartChanged method so that registered delegates receive the event.
