'Declaration
 
Protected Overridable Sub OnDropDownOpening( _
   ByVal e As DropDownOpeningEventArgs _
) 

'Usage
 
Dim instance As GcComboBox
Dim e As DropDownOpeningEventArgs
 
instance.OnDropDownOpening(e)

protected virtual void OnDropDownOpening( 
   DropDownOpeningEventArgs e
)

Parameters

e

A DropDownOpeningEventArgs instance contains the event data.

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