What is ScriptObject?

Simply,this is the managed code representation of complex javascript objects.

Confused?? Here is one scenario.Suppose there is a method in Javascript which returns a string value.We will call that method by simply executing HtmlPage.Invoke() method and process the return value as needed in silverlight.

This is possible because the javascipt function returns string.There is a proper mapping in silverlight to accept the value.What to do if javascript has to return the following object.

function GetDetails()
var me={Name:'joy',Company:'identitymine'};
return me;

How can silverlight recognize the object type?In this case we have to use ScriptObject.See more details about the class here in msdn

Below is the solution which solves the said scenario

private void btn_Click(object sender, RoutedEventArgs e){
ScriptObject obj = HtmlPage.Window.Invoke("GetDetails", "");
txtName.Text = (string)obj.GetProperty("Name");
