    From my aspx code behind page I would like to pass a param, in my case threadID, to the UploadHandler.

    Something like this


    How can I accomplish this, could I also pass multiple params?

     public MainPage()  
                Loaded += new RoutedEventHandler(Page_Loaded);  
            public void Page_Loaded(object sender, RoutedEventArgs e)  
                if (!String.IsNullOrEmpty(Request.QueryString["threadID"]) && !String.IsNullOrEmpty(Request.QueryString["threadTypeID"]))  
                    string threadID = Request.QueryString["threadID"];  
                    string threadTypeID = Request.QueryString["threadTypeID"];  
                    RadUploadSilverlightControl.AdditionalPostFields.Add("threadID", threadID);  
                    RadUploadSilverlightControl.AdditionalPostFields.Add("threadTypeID", threadTypeID);  

    I am still struggling to understand exactly what I am supposed to do.
    I need the threadID and threadTypeID in my UploadHandler. I put this code into the  MainPaige.xaml code behind (.xaml.cs) file
    but I am not sure if I am going about it the right way. If this is the way to do it then I guess I just have to add
    the System.Web.dll to my References in the Silverlight app so that it would find Request.Querystring.
    The way it is right now I am getting red lines under Request.Querystring. Could somebody
    confirm that what I am doing is correct or wrong, please!

    Hi Patrick,

    Sending parameters from the Html page to the Silverlight object is discussed in the Passing Parameters Into Silverlight Applications. There is a pretty good explanation plus a link to the video.

    In order to get familiar with custom parameters please preview the Passing custom params to the server side handler article.
