Definition

Namespace:

System.Windows.Forms.Design

Assembly:

System.Windows.Forms.dll

Raises the HelpRequested event.

protected:
 override void OnHelpRequested(System::Windows::Forms::HelpEventArgs ^ e);

protected override void OnHelpRequested (System.Windows.Forms.HelpEventArgs e);

override this.OnHelpRequested : System.Windows.Forms.HelpEventArgs -> unit

Protected Overrides Sub OnHelpRequested (e As HelpEventArgs)

Parameters

e

HelpEventArgs

A HelpEventArgs that contains the event data.

Remarks

The OnHelpRequested method shows the Help page that is associated with the component editor page, if there is one.

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

The OnHelpRequested 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 OnHelpRequested(HelpEventArgs) in a derived class, be sure to call the base class' OnHelpRequested(HelpEventArgs) method so that registered delegates receive the event.
