OnDropDownOpening Method (GcDateTimeEditingControl)


GrapeCity.Win.PluginInputMan Assembly > GrapeCity.Win.Spread.InputMan.CellType Namespace > GcDateTimeEditingControl Class : OnDropDownOpening Method
A DropDownOpeningEventArgs instance that contains the event data.
Raises the GcDateTime.DropDownOpening event.
Syntax
'Declaration
 
Protected Overrides Sub OnDropDownOpening( _
   ByVal e As DropDownOpeningEventArgs _
) 
'Usage
 
Dim instance As GcDateTimeEditingControl
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.
