OnBeforeObjectChanged Method
Summary
Raises the BeforeObjectChanged event.
Syntax
protected virtual void OnBeforeObjectChanged(Leadtools.Annotations.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.
