Navigation from an application that is running in partial trust:

  • To a Uri that is not located at the site of origin, or

  • targetFrameName name is not null or empty.

Use the Navigate(String, String, Byte[], String) method to navigate to a URL that may include escape characters. Use the Navigate(Uri, String, Byte[], String) method to navigate to a Uri that does not include escape characters.

The following example shows how to navigate to a document and open it in a new browser window by specifying the "about:blank" target.

    <StackPanel Orientation="Horizontal">
        <TextBox x:Name="addressTextBox" Width="200" />
        <Button Click="goNavigateButton_Click">Go</Button>
    <WebBrowser x:Name="myWebBrowser" />
private void goNavigateButton_Click(object sender, RoutedEventArgs e)
    // Get URI to navigate to
    Uri uri = new Uri(this.addressTextBox.Text, UriKind.RelativeOrAbsolute);

    // Only absolute URIs can be navigated to
    if (!uri.IsAbsoluteUri)
        MessageBox.Show("The Address URI must be absolute eg 'http://www.microsoft.com'");

    // Navigate to the desired URL by calling the .Navigate method
    this.myWebBrowser.Navigate(uri, "_blank", null, null);
