'Declaration
 
Protected Overridable Sub OnInvalidInput( _
   ByVal sender As Object, _
   ByVal e As EventArgs _
) 

'Usage
 
Dim instance As DropDownEditor
Dim sender As Object
Dim e As EventArgs
 
instance.OnInvalidInput(sender, e)

protected virtual void OnInvalidInput( 
   object sender,
   EventArgs e
)

Parameters

sender

An System.Object value that indicates the event sender.

e

The System.EventArgs instance that contains the event data.

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