OnBeforeObjectChanged Method

Summary

Raises the BeforeObjectChanged event.

Syntax

C#
VB
C++
protected virtual void OnBeforeObjectChanged( 
   AnnBeforeObjectChangedEventArgs e 
) 
  
Protected Overridable Sub OnBeforeObjectChanged( _ 
   ByVal e As Leadtools.Annotations.AnnBeforeObjectChangedEventArgs _ 
)  
protected: 
virtual void OnBeforeObjectChanged(  
   Leadtools.Annotations.AnnBeforeObjectChangedEventArgs^ e 
)  

Parameters

e
An AnnBeforeObjectChangedEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. The OnBeforeObjectChanged 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 OnBeforeObjectChanged in a derived class, be sure to call the base class's OnBeforeObjectChanged method so that registered delegates receive the event.

Example

For an example, refer to BeforeObjectChanged.
