Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Adds an event handler for a named event on the HTML Document Object Model (DOM).

public:
 void AttachEventHandler(System::String ^ eventName, EventHandler ^ eventHandler);

public void AttachEventHandler (string eventName, EventHandler eventHandler);

member this.AttachEventHandler : string * EventHandler -> unit

Public Sub AttachEventHandler (eventName As String, eventHandler As EventHandler)

Parameters

eventName

String

The name of the event you want to handle.

eventHandler

EventHandler

The managed code that handles the event.

Remarks

The Managed Document Object Model (DOM) exposes only a select number of events. Most of the unexposed events are only defined for specific types of elements; such as the submit event, which is valid only on FORM elements. Use AttachEventHandler to add an event handler to these unexposed events.

You should not attach an event to the document or one of its objects until the document has completed loading. The earliest you should call this method is in the DocumentCompleted event of the WebBrowser control.

For more information about the available unmanaged events, see Accessing Unexposed Members on the Managed HTML Document Object Model and the IHTMLElement interfaces: IHTMLElement, IHTMLElement2, IHTMLElement3, IHTMLElement4.
