Sometimes it is necessary to see i.e. the full result you will get inside the asynchronous callback function to see all properties. The AjaxPro JavaScript includes a method to convert a JavaScript object into a JSON string.

<script type="text/javascript">

function myInvoke() {
    MyNamespace.MyClass.MyMethod(1, 2, 3, myCallback);   
}
   
function myCallback(res) {
   // The following line will display a message box
   // with the JSON serialized string of the result.
    alert(AjaxPro.toJSON(res.value));
   
   // To see all properties in the res object simple
   // use following command:
   alert(AjaxPro.toJSON(res));
}

</script>

For debugging this is very useful. Note: you should always check the res.Error property to see if there is any excption during your request.

On the server-side code you could use following line to get the JavaScript JSON representation of the .NET object:

List<string> list = new List<string> ();
list.Add ("Michael");
list.Add ("Tanja");
list.Add ("Marc Julian");
list.Add ("Jan Oliver");

string json = AjaxPro.JavaScriptSerializer.Serialize (list);

The output of the json string will be:

["Michael","Tanja","Marc Julian","Jan Oliver"]

You can use this feature to embedd any data structure already in the Page_Load event to your HTML output (JavaScript variable i.e.).
