Form::OnHelpButtonClicked Method (CancelEventArgs^)

.NET Framework (current version)

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)

Syntax

protected:
virtual void OnHelpButtonClicked(
	CancelEventArgs^ e
)

Parameters

e: Type: System.ComponentModel::CancelEventArgs^
A CancelEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

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