In This Topic
OnPopUpOpening Method (GcNumber)
In This Topic
Raises the PopUpOpening event.
Syntax
'Declaration
 
Protected Overridable Sub OnPopUpOpening( _
   ByVal e As PopUpOpeningEventArgs _
) 
 
'Usage
 
Dim instance As GcNumber
Dim e As PopUpOpeningEventArgs
 
instance.OnPopUpOpening(e)

Parameters

e
A PopUpOpeningEventArgs instance contains the event data.
Remarks
Raising an event invokes the event handler through a delegate.

The OnPopUpOpening 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 OnPopUpOpening in a derived class, be sure to call the base class's OnPopUpOpening method so that registered delegates receive the event.
