javascript - DropDown is not populating in KENDO Grid -

-

i not able populating data in kendo dropdown data coming form database. here code kendo dropdown:

function positiondropdowneditor(container, options) {     $('<input name="size" required data-bind="value:' + options.field + '"/>')         .appendto(container)         .kendodropdownlist({          autobind: false,          datatextfield: "name",          datavaluefield: "id",            datasource: {                         transport: {                             read: {                                 datatype: "json",                                 url: "/employee/allposition",                             }                         }                     }          }); }

and controller data coming from:

public jsonresult allposition() {     employeeservice employeeservice = new employeeservice();     list<position> positions= employeeservice.getallposition();     return json(positions); }

whats wrong here data not populating inside dropdown? plz explain including "container, options" , value contain , why need use?

thank you

after concerning whole day , try, solved problem. hope others. silly, took whole day. found problem in allposition(). here return type sting. code be:

public string allposition()     {         employeeservice employeeservice = new employeeservice();         list<position> positions= employeeservice.getallposition();         var x = jsonconvert.serializeobject(positions);               return x;     }

dont ask me why return "jsonconvert.serializeobject(positions)" not return "json(positions)". had convert return type jsonresult string.

thanks concern , tried help.
