Answer 1

First make sure that the page is finalized; most probably by detaching all the event handlers you manually attached before. Then (sooner or later) the page will be finalized which in turns disposes of the webview.

A similar effect would be achieved by forward navigating the webview to an empty html page.

Here is the solution: Invoke the UnLoaded event of WebView - webView.Unloaded += webView_UnLoaded;

Then change the source of the webview in webView_UnLoaded event handler: Here is my code:

private void webView_UnLoaded(object sender, RoutedEventArgs e)
    {
        WebView webView = (WebView)sender;
        webView.Source = new Uri(" ");
    }
