Silverlight with dynamic height

I have a silverlight app that I want to allow size like a regular HTML page. That is, I want the size of the silverlight plugin to expand and shrink in height to accommodate the dynamic data and controls with which I populate the silverlight application. So, let's say I have a page with a grid and a button. The user presses the button and the grid receives a bunch of lines with images making the natural size of the grid higher than the browser window. I would like to have something in place to resize the silverlight plugin to suit the desired mesh size. The following and several other attempts do not work:

// handler in my main page.
 void MainGrid_LayoutUpdated(object sender, EventArgs e)
 {
     HtmlPage.Window.Invoke("setSilverlightSize", this.MainGrid.DesiredSize.Height);
 }

<body style="height:100%;margin:0;">
    <form id="mainForm" runat="server" style="height:100%;">
        <asp:ScriptManager ID="ScriptManager" runat="server"></asp:ScriptManager>
        <div id="SilverlightContainer"  style="height:100%;">
            <asp:Silverlight ID="SLMain" runat="server" Source="~/ClientBin/My.Silverlight.Main.xap" Version="2.0" Width="100%" Height="100%" />
        </div>
    </form>
    <script type="text/javascript">
        function setSilverlightSize(val) {
            var host = document.getElementById("SilverlightContainer");
            host.style.height = val + "px";
        }
    </script>
</body>

Desired size MainGrid always wants to be the size of the window. Arg told the pirate.

, javascript HTML-:

/*
When Silverlight is loaded attach silverlight events
*/
function OnSilverlightLoaded(sender, args) {
    //Getting Silverlight object on page
    _silverlightControlHost = document.getElementById("SilverlightObject");
    //Subscribe to it events
    _silverlightControlHost.Content.SilverlightApp.SetHeightEvent = SetHeightEvent;
}

Silverlight:

[ScriptableType]
public partial class MainPage
{
    //Register the event to be as accessible from script
    [ScriptableMember]
    public event EventHandler<HeightEventHandler> SetHeightEvent;

    public MainPage()
    {
        InitializeComponent();

        //Register this instance to be accessible from script
        HtmlPage.RegisterScriptableObject("SilverlightApp", this);
    }

    public void SomeMethod()
    {
        if (this.SetHeightEvent != null)
            this.SetHeightEvent(this, new HeightEventHandler() { Altura = _heightSilverObj.ToString() });
    }
}

[ScriptableType]
public class HeightEventHandler : EventArgs
{
    public string Altura { get; set; }
}

void Page_Loaded(object sender, RoutedEventArgs e)
{
        SetupPage();
        this.ValidationSummary.SizeChanged += new SizeChangedEventHandler(ValidationSummary_SizeChanged);

EDIT: ​​ Javascript cs

    function ResizeObject(height) {
        var host = document.getElementById("uploaderHost");
        host.style.height = height + "px";
    }

public void ResizeSilverlightObject(double height)
    {
       HtmlPage.HtmlWindow.Invoke("ResizeObject", new object[] { height });
