Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
public delegate void WebBrowserNavigatingEventHandler( Object^ sender, WebBrowserNavigatingEventArgs^ e )
- Type: System::Object
The source of the event.
- Type: System.Windows.Forms::WebBrowserNavigatingEventArgs
A WebBrowserNavigatingEventArgs that contains the event data.
When you create a delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates.
The following code example demonstrates how to use a handler for the WebBrowser::Navigating event to cancel navigation when a Web page form has not been filled in. The WebBrowser::Document property is used to determine whether the form input field contains a value. This example requires that your form contains a WebBrowser control called webBrowser1.
