Asp.Net MVC Sending JSON As a String Always Truncated on Server

Question

I am sending json data as a string to the server in asp.net mvc as shown in the following;

var dto = JSON.stringify(transObj);
                    console.log(String(dto));
$.ajax({
                    url: "/home/activity",
                    dataType: 'html',
                    data: "obj=" + String(dto) + "&trackedFromEntityTypeId=" + trackedFromEntityTypeId + "&trackedFromEntityType=" + trackedFromEntityType,
                    type: 'POST',
                    success: function (data) {
                        var jsonResult = JSON.parse(data);
                        if (jsonResult.status) {
                            bootbox.alert(jsonResult.message, function () {
                                window.location.href = "/";
                            });
                        } else {
                            displayError('Something bad happend. ' + data.message);
                        }
                    },
                    error: function (error) {
                        displayError('Something bad happend. ' + error.statusText);
                    },
                    complete: function () {
                        $.unblockUI();
                    }

                });

As you can see before it goes to the server, iam writing the string to the console. When i open the console window, the data shown in json format as expected but on the server the string is truncated as shown the following picture; However, the orignal json data in console window is shown below (as expted). i also used the jsonformatter to format the data as json and its formating the data properly;

Answer 1

Just figured it out with the help of @Alexei Levenkov comment. The problem was, i was preparing data manually and sending the data to the server using query string format. Howerver, the method i choose is POST. So i just prepare a javascript object and then send it as an object to the server;

var dto = { "obj": JSON.stringify(transObj), "trackedFromEntityTypeId": trackedFromEntityTypeId, "trackedFromEntityType": trackedFromEntityType };
 $.ajax({
                        url: "/home/activity",
                        dataType: 'html',
                        data: dto,
                        type: 'POST',
                        success: function (data) {
                            var jsonResult = JSON.parse(data);
                            if (jsonResult.status) {
                                bootbox.alert(jsonResult.message, function () {
                                    window.location.href = "/";
                                });
                            } else {
                                displayError('Something bad happend. ' + data.message);
                            }
                        },
                        error: function (error) {
                            displayError('Something bad happend. ' + error.statusText);
                        },
                        complete: function () {
                            $.unblockUI();
                        }

                    });
