could you let us know which server code you are executing for json serialization?

this is your responsibility to return data as json, first make json in GetRptDetails method and return that json string and you will get things working.

Member 10628913 27-Feb-14 5:52am

so wat should i do.kindly suggest.

Member 10628913 27-Feb-14 5:55am

Faisalabadians 27-Feb-14 6:30am

use newtson json or JavaScriptSerializer to make data as json, newtonsoft.json is pretty good and usefull. here is link and use nuget package and search for "newtonsoft.json" and install this package http://james.newtonking.com/json/help/index.html
