   ByVal e As AnnPaintEventArgs _
)

'Usage
 
Dim instance As AnnContainer
Dim e As AnnPaintEventArgs
 
instance.OnBeforeDrawingObjects(e)

protected virtual void OnBeforeDrawingObjects( 
   AnnPaintEventArgs e
)

 function Leadtools.Annotations.AnnContainer.OnBeforeDrawingObjects(

)

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.
