protected override void OnDropDownOpening(DropDownOpeningEventArgs e)
Protected Overrides Sub OnDropDownOpening(e As DropDownOpeningEventArgs)
Type | Name | Description |
---|---|---|
DropDownOpeningEventArgs | e | A DropDownOpeningEventArgs instance that contains the event data. |
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.
