                            if (data == 1 || data == -1) {
                                if (btnevent == "Save")
                                {

                                        fadeOut: 1500,
                                        onHidden: function () {
                                            window.location.reload();
                                        }
                                    });
                                } else {
                                    toastr.success('', 'TC Updated Successfully!!', {
                                        timeOut: 1500,
                                        fadeOut: 1500,

                            }
                            else {
                                toastr.error("Something went to wrong");
                            }
                        },
                        //error: function () { alertify.alert('Error. Please try again.'); }
                    });

an array is passed from ajax but doesn't get on the controller side. here I upload of ajax passed value and controller get value

here JSON response in the console

can anyone have a solution then please help me. thank you in advance

I just realized, looking at your print screen, that each item of you array is another array. And not a object. Can you share a plain text json that is sent on your request? — Lutti Coelho

@Lutti Coelho Ya Sure, I update my question with JSON screenshot — Niharika

Could you try updating controller action signature to public ActionResult GenerateTC(TCMain tm, List<List<object>> tcval) — sam

I think you need to define a complex object Like this :

public class MyModel
{
  public TCMain tm {get;set;}
  public List<MyArray> tcval{get;set;} 
}

And the MyArray object should be like this :

public class MyArray
 {
   public string PONO{get;set;}
   public string Dieno{get;set;}
   // and other properties

 }

And here your action :

[HttpPost]
Public ActionResult GenerateTC(MyModel model)

And your JSON setting data section :

var rawData = {"tm" : sendingValue, "tcval" : customers};
data : JSON.stringify({"model":rawData}),

. . . .

I checked the code again, and finally I got value in the action by changing the below part :

$("#detailtbl TBODY TR:not(:last-child)").each(function (index) {
             if (index > 3) {
                var row = $(this);
                var customer = []; // ================> var customer ={};
                var hd = tblHeader[0];
                for (var i = 0; i < row.find("TD").length; i++) {
                    var hrd = hd[i];
                    customer[hrd] = row.find("TD").eq(i).html();
                }
                customers.push(customer);
             }
        });

Now, to cast the parameter value to your model you need to use specific ModelBinder or do it manually for this specific action

but my properties are dynamic (no specific property in MyArray)

Matt Ghafouri Over a year ago

So just change this property like this : public List<object> tcval{get;set;} because of this, you need to cast it to the MyArray after you get the value in the action

Niharika Over a year ago

still not getting the value in the controller :(

Matt Ghafouri Over a year ago

As @Lutti said, try this = > data : {"model":rawData}

Niharika Over a year ago

I tried but not working... if I remove JSON.stringify my control not pass to the controller

You don't need to stringfy your json data.

You can replace this:

JSON.stringify({ "tm": sendingvalue,"tcval":customers}),

to this:

{tm: sendingvalue, tcval: customers}),

if I do so my control not pass to the controller :(

Lutti Coelho Over a year ago

Do you look the difference between each approach on request tab of developers tools? Both should send a json on the request.
