Here is how you could simulate the click action on your login button:

webView.InvokeScript("eval", new[] { "document.getElementById(\"login\").click();" });

Here is the code if you want to get notified when the button is clicked: Register for LoadComplete and use the folowing code to add a click handler:

private void WebView_OnLoadCompleted(object sender, NavigationEventArgs e)
    {

        webView.InvokeScript("eval", new[]
        {
            "var loginButon=document.getElementById(\"login\");" +
            "if (loginButon.addEventListener) {" +
                "loginButon.addEventListener(\"click\", clickFunction, false);" +
            "} else {" +
                "loginButon.attachEvent('onclick', clickFunction);" +
            "}  " +
            "function clickFunction(){" +
                " window.external.notify('loginClick');"+
             "}"
        });

    }

In the page constructor enable web view notification, you should specify the uri of the page you are working on or you can enable all uri:

webView.AllowedScriptNotifyUris = WebView.AnyScriptNotifyUri;

Finally register for the ScriptNotify event and use the following handler :

private void WebView_OnScriptNotify(object sender, NotifyEventArgs e)
    {
        if (e.Value == "loginClick")
        {
            //Login button have been clicked
        }
    }
