WebBrowser.DocumentCompleted Event

Occurs when the WebBrowser control finishes loading a document.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public event WebBrowserDocumentCompletedEventHandler DocumentCompleted

The WebBrowser control navigates to a new document whenever one of the following properties is set or methods is called:

Handle the DocumentCompleted event to receive notification when the new document finishes loading. When the DocumentCompleted event occurs, the new document is fully loaded, which means you can access its contents through the Document, DocumentText, or DocumentStream property.

To receive notification before navigation begins, handle the Navigating event. Handling this event lets you cancel navigation if certain conditions have not been met, for example, when the user has not completely filled out a form. Handle the Navigated event to receive notification when the WebBrowser control finishes navigation and has begun loading the document at the new location.

For more information about handling events, see Consuming Events.

The following code example demonstrates the use of this event to print a document after it has fully loaded.


private void PrintHelpPage()
{
    // Create a WebBrowser instance. 
    WebBrowser webBrowserForPrinting = new WebBrowser();

    // Add an event handler that prints the document after it loads.
    webBrowserForPrinting.DocumentCompleted +=
        new WebBrowserDocumentCompletedEventHandler(PrintDocument);

    // Set the Url property to load the document.
    webBrowserForPrinting.Url = new Uri(@"\\myshare\help.html");
}

private void PrintDocument(object sender,
    WebBrowserDocumentCompletedEventArgs e)
{
    // Print the document now that it is fully loaded.
    ((WebBrowser)sender).Print();

    // Dispose the WebBrowser now that the task is complete. 
    ((WebBrowser)sender).Dispose();
}
