I have the following class which is used to serialize an IDictionary
object to either XML or JSON.
When serializing to JSON, it seems the AjaxNonSerializable attribute is
ignored, so both the
Table and Items[] properties get serialized.
Am I do something wrong or is this a bug?
Tried this with AjaxPro.dll 6.9.22.2 and 6.10.6.2
<snip psuedocode>
Hashtable obj = new Hashtable(); // or ListDictionary..
// populate hashtable
if xml
string output = ((SimpleDictionary)obj).Serialize();
else
string output = AjaxPro.JavaScriptSerializer.Serialize(obj);
