ButtonBase.OnMouseMove Method

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Raises the OnMouseMove event.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
'Declaration
Protected Overrides Sub OnMouseMove ( _
	mevent As MouseEventArgs _
)

Parameters

mevent
Type: System.Windows.Forms.MouseEventArgs

A MouseEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnMouseMove 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.

NoteNote

Do not call OnMouseMove if the button is disabled (this includes calls to the base class's OnMouseMove method when you override OnMouseMove in a derived class). When disabling the button in an override of OnMouseMove, call the base class's OnMouseMove method before disabling the button, or do not call it at all.

Notes to Inheritors

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