GrapeCity.Win.PluginInputMan Assembly > GrapeCity.Win.Spread.InputMan.CellType Namespace > DropDownEditor Class : OnKeyUp Method |
'Declaration Protected Overridable Sub OnKeyUp( _ ByVal sender As Object, _ ByVal e As KeyEventArgs _ )
'Usage Dim instance As DropDownEditor Dim sender As Object Dim e As KeyEventArgs instance.OnKeyUp(sender, e)
protected virtual void OnKeyUp( object sender, KeyEventArgs e )
The OnKeyUp 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 OnKeyUp in a derived class, be sure to call the base class's OnKeyUp method so that registered delegates receive the event.
