.NET Windows Forms in a Nutshell

Name

HelpEventArgs

Synopsis

This class encapsulates the event arguments for the Control.HelpRequested event. It includes a Handled property, which you should set to true if you do handle the event, or the framework will pass the event on for further processing.

You can also retrieve the current MousePos if you need to use this to resolve the help item.

You can display help using the Help class, or use the HelpProvider component to provide automated help support.

public class HelpEventArgs : EventArgs {

// Public Constructors
