Problem with scriptable objects

Question

 Hi,

I would like to send an event to my javascript when I'm done with a certain action within Silverlight code (like upload succeeded) .

For that purpose I would like to use a scriptable object.

In the onLoad function in javascript, I get this error "Trying to get unsupported property on scriptable plugin object!". And I can see in the Debugger that control.Content doesn't have a property SilverlightControl although this is the name I used when I call RegisterScriptableObject in my C# code.

Here is my java script:

       

        function uploadSuccess(sender, args)
        {
            alert('Upload succeeded!');
        }
       
        function onLoad()               // call the onLoad function on the body onLoad event.
        {
            control= document.getElementById('Xaml1');  //Xaml1 is the id of my silverlight object in html
            control.Content.SilverlightControl.OnUploadSuccedeed = uploadSuccess;
        }

 

Here is my code:

 [ScriptableType]
    public class UploadSuccessEvent
    {
        [ScriptableMember]
        public event EventHandler Event;

        public virtual void OnEvent(UploadSuccessEventArgs e)
        {
            Event(this, e);
        }
    }

    [ScriptableType]
    public class UploadSuccessEventArgs : EventArgs
    {
        private string value;

        [ScriptableMember]
        public string Value
        {
            get { return this.value; }
            set { this.value = value;  }
        }
    }

    public partial class Page : UserControl
    {

        public UploadSuccessEvent UploadSuccessEvent = new UploadSuccessEvent();
 

        public Page()
        {
            InitializeComponent();
            Loaded += new RoutedEventHandler(Page_Loaded);
        }
 

        void Page_Loaded(object sender, RoutedEventArgs e)
        {
            HtmlPage.RegisterScriptableObject("SilverlightControl", UploadSuccessEvent);
        }
 

        private void Button_Click(object sender, RoutedEventArgs e)

        {

           uploadSuccessEvent.OnEvent(null);                 //At that point I get a null reference exception because uploadSuccessEvent.Event is null.

            ...... 

        }
 

    } 

 

Does anybody have an idea?

Thank you 

Answer 1

if you have javascript function like

abc(a)

{

 alert(a);

} 

then call like below code

  HtmlPage.Window.Invoke("abc","sachin");

for using this add

using System.Windows.Browser; 

C# 

 HtmlPage.Window.Invoke("abc","sachin");

Answer 2

 Thanks, your solution is much easier than the scriptable objects.
