OnKeyDown Method (DropDownEditor)


GrapeCity.Win.PluginInputMan Assembly > GrapeCity.Win.Spread.InputMan.CellType Namespace > DropDownEditor Class : OnKeyDown Method
An System.Object value that indicates the event sender.
The System.Windows.Forms.KeyEventArgs instance that contains the event data.
Raises the KeyDown event.
Syntax
'Declaration
 
Protected Overridable Sub OnKeyDown( _
   ByVal sender As Object, _
   ByVal e As KeyEventArgs _
) 
'Usage
 
Dim instance As DropDownEditor
Dim sender As Object
Dim e As KeyEventArgs
 
instance.OnKeyDown(sender, e)
protected virtual void OnKeyDown( 
   object sender,
   KeyEventArgs e
)

Parameters

sender
An System.Object value that indicates the event sender.
e
The System.Windows.Forms.KeyEventArgs instance that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate.

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