In This Topic
OnDropDownOpened Method (GcTextBox)
In This Topic
Raises the DropDownOpened event.
Syntax
'Declaration
 
Protected Overridable Sub OnDropDownOpened( _
   ByVal e As EventArgs _
) 
 
'Usage
 
Dim instance As GcTextBox
Dim e As EventArgs
 
instance.OnDropDownOpened(e)

Parameters

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