Passing parameters in Silverlight URL

Passing parameters in Silverlight URL

I have developed a Silverlight RIA Application. Assume the site link is http://MySilverlightApp In my main.xaml page I navigate to a different view (e.g Page1). So when I go to http://MySilverlightApp I get routed to http://MySilverlightApp/#/Page1

In this Page1.xaml I display a list of radio buttons. Each radio button has an ID and upon selecting a radio button I display further things on the page.

I want to pass that ID from url itself, like http://MySilverlightApp/#/Page1?ID=13

Then when my page loads I can grab that ID and select the radio button (with ID 13) and display the material right there.

How can I accomplish this ? I want to grab the string not in code behind but in Page1 view model. (not binding, just want to retrieve value)

Ok this is what I did.

In my code behind I introduced a property to query and find out if any parameters are passed or not.

private string ParamValue         {             get             {                 string paramValue = "";                 const string paramName = "ID";                  if (NavigationContext.QueryString.ContainsKey(paramName))                     paramValue = NavigationContext.QueryString[paramName];                  return paramValue;             }         } 

In my Loaded Event handler I invoke the view model's public method and pass in the ID. Something like

private void Page1_Loaded(object sender, RoutedEventArgs e)         {             if (!String.IsNullOrEmpty(ParamValue))             {                 Page1iewModel page1ViewModel = this.DataContext as Page1ViewModel ;                 page1ViewModel.SetID(ParamValue);             }         }
