QueryAccessibilityHelpEventArgs

QueryAccessibilityHelpEventArgs

---

System. Windows .Forms (system. windows .forms.dll)

class

When an accessibility client (such as a screen reader) requires help information from a Control , it raises the QueryAccessibilityHelp event, to allow you to provide custom help information. This class encapsulates the data for this event.

You should set the HelpNamespace (the URI of the help file), the HelpKeyword (the topic ID within that file, as a string), and the HelpString (the What's This? help information) for the control on which help is requested .

 public class  QueryAccessibilityHelpEventArgs  : EventArgs {  // Public Constructors  public  QueryAccessibilityHelpEventArgs  ();    public  QueryAccessibilityHelpEventArgs  (string  helpNamespace  , string  helpString  , string  helpKeyword  );  // Public Instance Properties  public string  HelpKeyword  {set; get; }    public string  HelpNamespace  {set; get; }    public string  HelpString  {set; get; } }
