Awesomium - Return Javascript Result to C#

Question

Javascript / HTML Code

<script type="text/javascript">
function configurator(clicked) { 
return clicked.name;   
} 
</script>

<a name="link1" href="#" onclick="configurator(this)">Link 1</a>
<a name="link2" href="#" onclick="configurator(this)">Link 2</a>

I want to return the "clicked.name" value to let's say "result" variable in C# when onclick event on the link triggered. I don't know how to do that. Could someone help me...

Note: I'm still very new to Awesomium :)

Update:

I follow @JonnyReeves method with a little modified:

using (JSObject myGlobalObject = webControl1.CreateGlobalJavascriptObject("myGlobalObject"))
{
    myGlobalObject.Bind("onLinkClicked", true, (sen, eve) =>
    {
        MessageBox.Show(Convert.ToString(sen));
    });
}

but I got "Awesomium.Windows.Controls.WebControl" as result not the clicked link's name.

Ajax. It is not possible to simply return data to the server, but you can make a separate request and pass the data along with it. — Jonathan Lonowski

I'm not using any web server. I'm just using Awesomium (WebControl) as browser. I still learning how to exchanging data between C# and html (Awesomium). — Reyn

It looks like you you could make use of Awesomium's JSObject.bind method to invoke a C# method from JavaScript. A typical approach would be to expose a JavaScript global object which includes all your 'bridge' methods (ie: those that pass data between C# and JavaScript).

// Create and acquire a Global Javascript object.
// These object persist for the lifetime of the web-view.
using ( JSObject myGlobalObject = webView.CreateGlobalJavascriptObject( "myGlobalObject" ) )
{
    // The handler is of type JavascriptMethodEventHandler. Here we define it
    // using a lambda expression.
    myGlobalObject.Bind( "onLinkClicked", false, ( name ) =>
    {
        Debug.Print( String.Format( "User clicked: {0}", name ) );
    } );
}

You can now invoke this method from your JavaScript code:

<script type="text/javascript">
    function configurator(clicked) 
    { 
           myGlobalObject.onLinkClicked(clicked.name);
    } 
</script>

I tried your code but got error on "Delegate 'Awesomium.Core.JavascriptMethodEventHandler' does not take 1 arguments" so I changed your code a little (see OP). But I can't get the clicked link's name (<a name="link1">).
