protected virtual void OnDropDownOpened( 
   EventArgs e
)

'Declaration
 
Protected Overridable Sub OnDropDownOpened( _
   ByVal e As EventArgs _
) 

'Usage
 
Dim instance As GcNumber
Dim e As EventArgs
 
instance.OnDropDownOpened(e)

Parameters

e

A System.EventArgs instance contains the event data.

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