OnDropDownOpening Method (GcNumberEditingControl)

Raises the GcNumber.DropDownOpening event.

Syntax

Visual Basic
C#

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

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

protected override void OnDropDownOpening( 
   DropDownOpeningEventArgs e
)

Parameters

e: A DropDownOpeningEventArgs instance that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. 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.
