OnBeforeDrawingObjects Method

Show in webframe





An RasterCollection<AnnPaintEventArgs> that contains the event data.
Raises the BeforeDrawingObjects event.
Syntax
protected virtual void OnBeforeDrawingObjects( 
   AnnPaintEventArgs e
)
'Declaration
 
Protected Overridable Sub OnBeforeDrawingObjects( _
   ByVal e As AnnPaintEventArgs _
) 
'Usage
 
Dim instance As AnnContainer
Dim e As AnnPaintEventArgs
 
instance.OnBeforeDrawingObjects(e)

            

            
protected:
virtual void OnBeforeDrawingObjects( 
   AnnPaintEventArgs^ e
) 

Parameters

e
An RasterCollection<AnnPaintEventArgs> that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. The OnBeforeDrawingObjects 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 OnBeforeDrawingObjects in a derived class, be sure to call the base class's OnBeforeDrawingObjects method so that registered delegates receive the event.
Example
For an example, refer to BeforeDrawingObjects.
