jquery - Asp.net MVC deserialize Kendo Grid data in the controller -

-

i have asp.net mvc 4 application. have view kendo.grid , want send ajax (json.stringify) data of grid @ controller.

my problem controller receives list of string , don't know how deserialize json data.

code

this object contained in rows of grid:

public class coursedto {     public string codcourse { get; set; }     public string descourse { get; set; } }

this definition of grid in view:

@(html.kendo().grid<coursedto>()     .name("gridcourses")     .columns(columns =>     {         columns.bound(c => c.codcourse);         columns.bound(c => c.descourse);     })     .datasource(datasource => datasource         .ajax()         .serveroperation(false)         .read("getallcourses", "controllercourses")     ) )

this ajax call controller jquery:

function passthegrid() {     $.ajax({         url: "@url.action("showcourses")",         type: "post",         data: {             courses : json.stringify($("#gridcourses").data("kendogrid").datasource.data());        },         success: function (response) {             $("#coursesdiv").html(response);         }     }); }

this controller:

[httppost] public partialviewresult showcourses(list<string> courses) {     javascriptserializer js = new javascriptserializer();     list<string> temp= new list<string>();     foreach (var singlecourse in courses)     {         temp.add(js.deserialize<string>(singlecourse));     }     ...     return partialview("_viewcourses"); }

in example have cource in grid , when pass data ajax @ controller, parameter "courses" contains string:

[{"codcourse":"privsic0102006","descourse":"multimedia - privacy , security"}]

but error when try deserialize:

type 'system.string' not supported deserialization of matrix

question

how deserialize json data in controller correctly?

i resolved changing code:

call ajax

function passthegrid() {     var o = kendo.observable({         mycourses: $("#gridcourses").data("kendogrid").datasource.data()     });     var courses = json.stringify(o);     $.ajax({         url: "@url.action("showcourses")",         type: "post",         data: {             courses : courses ,         success: function (response) {             $("#coursesdiv").html(response);         }     }); }

the ajax call pass data:

{"mycourses":[{"codcourse":"privsic0102006","descourse":"multimedia - privacy , security"}]}

the controller

[httppost] public partialviewresult showcourses(string courses) {     var coursesjson = jobject.parse(courses).selecttoken("mycourses").tostring();      var courseslist = jsonconvert.deserializeobject<list<coursedto>>(coursesjson);     ...     return partialview("_viewcourses"); }

and course list contains object coursedto.
