Question

i am developing a site using asp.net but for displaying graphs we are using silverlight technology.

last but not least i have a back button on silverlight .xmal page if user click on that back button i need to redirect him to aspx page, how can i achieve that?

Answer 1

this is how you can get query string in silverlight

 public static string GetQueryStringValue(this System.Windows.Controls.Page page, string p)
        {

            var values = HtmlPage.Document.QueryString
            .Where(w => w.Key.Trim().Equals(p))
            .Select(s => s.Value).SingleOrDefault();
            return values;
        }

        public static string GetQueryStringValueFromNavigationContext(this System.Windows.Controls.Page p, string key)
        {
            var values = p.NavigationContext.QueryString
            .Where(w => w.Key.Trim().Equals(key))
            .Select(s => s.Value).SingleOrDefault();
            return values;
        }
