Question

Hosting and interacting with a webpage inside a WPF App.

Answer 1

+1 A:

You can host a web page in a WPF application using the WebBrowser controls that was added in .NET 3.5 SP1:

<Grid>
 <WebBrowser Name="browser" />
</Grid>

And in the code-behind you have to set the Uri to your page and an object (which should be com-visible) that is to be called from the java script:

public partial class Window1 : Window
{
 public Window1()
 {
  InitializeComponent();

  string uri = AppDomain.CurrentDomain.BaseDirectory + "TestPage.html";
  this.browser.Navigate(new Uri(uri, UriKind.Absolute));
  this.browser.ObjectForScripting = new ScriptingHelper();
 }

 [ComVisible(true)]
 public class ScriptingHelper
 {
  public void ShowMessage(string message)
  {
   MessageBox.Show(message);
  }
 }
}

And finally in your page you must call the code using window.external like below:

<head>
 <title></title>

 <script type="text/javascript">
  function OnClick()
  {
   var message = "Hello!";
   window.external.ShowMessage(message);
  }
 </script>
</head>
<body>
 <a href="#" onclick="OnClick()">Click me</a>
</body>
