How to Post JSON Data to an MVC5 Controller via Ajax

It's just a simple form where you enter your first name and last name, and then use a multiselect dropdown to pick your favorite bands.


and enter your First name, Last name and select your favorite Car.

Step 1: First Create PersonController.css

        public ActionResult Index()
            return View(new PersonModel());

        public JsonResult BadSave(string first, string last, List<string> favoriteBands)
            Console.WriteLine(String.Join(" ",favoriteBands));

            return Json(new { result = "saved the bad way" });

        public JsonResult GoodSave(PersonModel model)
            Console.WriteLine(String.Join(" ", model.FavoriteBands));

            return Json(new { result = "saved the good way" });


Step 2 : Create PersonModel.css Model

public class PersonModel
        [DisplayName("First Name")]
        public string First { get; set; }

        [DisplayName("Last Name ")]
        public string Last { get; set; }

        [DisplayName("Favorite Car")]
        public List<string> FavoriteBands { get; set; }

Step 3 : Create the View ie Index.cshtml

@model MVCJsonPost.Models.PersonModel
    ViewBag.Title = "Home";
    Layout = "~/Views/Shared/_Layout.cshtml";


    @Html.LabelFor(m => m.First)
    @Html.EditorFor(m => m.First)

    @Html.LabelFor(m => m.Last)
    @Html.EditorFor(m => m.Last)

    @Html.LabelFor(m => m.FavoriteBands)
    @Html.DropDownListFor(m => m.FavoriteBands, new SelectList(
                  new List<Object>{ 
                       new { value = 0 , text = "Honda City"  },
                       new { value = 1 , text = "Renault fluence" },
                       new { value = 2 , text = "Hyundai xcent"}
                    new { multiple = "multiple" })


    <input type="button" value="Bad Submit" id="bad" />
    <input type="button" value="Good Submit" id="good" />

<label id="result"></label>

Step 4: Create the js file i.e person.js in Script Folder

$(document).ready(function () {
    $('#good').click(function () {
        var request = new PersonModel();
            url: "Person/GoodSave",
            dataType: 'json',
            contentType: "application/json",
            type: "POST",
            data: JSON.stringify(request), //Ahhh, much better
            success: function (response) {

    $('#bad').click(function () {
        var request = new PersonModel();
            url: "Person/BadSave",
            dataType: 'json',
            type: "POST",
            data: "first=" + request.First + "&last=" + request.Last + "&favoriteBands=" + request.FavoriteBands, //How do you encode an array?? This doesn't even work right
            success: function (response) {

function PersonModel() {
    var self = this;
    self.First = $("#First").val();
    self.Last = $("#Last").val();

    self.FavoriteBands = $.map($('#FavoriteBands option:selected'),
                      function (e) { return $(e).val(); });

Run The Application  and fill the form and place some breakpoint to test and debug line by line

Done :)

How to Integrate Payzippy Payment gateway in Asp.net3.5 ?

Payzippy is one of the latest and Fast growing  payment gateway providing service in India(fom flipkart.com). They are providing SDK for PHP and Java but still no SDK for .NET platform. But Using Payzippy Rest API (support for JSON) , We can create Payment Integration in ASP.NET .

            this.EnableViewState = false;
       private static string secretKey = "KEY_KEY_KEY_KEY_KEY";
        private static string generateSHA256(String input)
            SHA256Managed crypt = new SHA256Managed();
            string hash = String.Empty;
            byte[] crypto = crypt.ComputeHash(Encoding.ASCII.GetBytes(input), 0, Encoding.ASCII.GetByteCount(input));
            foreach (byte bit in crypto)
                hash += bit.ToString("x2");
            return hash;
        static string GenHash(Dictionary<string, string> chargingParams)
            // Acquire keys and sort them.
            List<string> list = new List<string>(chargingParams.Keys);
            StringBuilder stringForHash = new StringBuilder();
            // Loop through keys.
            foreach (var key in list)
                stringForHash.Append(chargingParams[key] + '|');
            return generateSHA256(stringForHash.ToString());
        public Dictionary<string, string> chargingParams;
        private void Main()
            var currentTime = DateTime.Now.Ticks / TimeSpan.TicksPerMillisecond;

            this.chargingParams = new Dictionary<string, string>();
            chargingParams.Add("merchant_id", "test"); //Your MID issued by PayZippy.
            chargingParams.Add("buyer_email_address", "email@gmail.com"); // Email Address
            chargingParams.Add("merchant_transaction_id", "PAY_" + currentTime); //Your Transaction Id
            chargingParams.Add("transaction_type", "SALE"); //This is the default Value.
            chargingParams.Add("transaction_amount", "10000"); //Amount must be in paise. So, 1 Rupee= 100.
            chargingParams.Add("payment_method", "CREDIT"); // CREDIT,DEBIT,EMI,NET
            chargingParams.Add("bank_name", ""); //Bank Name required in case of EMI/NET.
            chargingParams.Add("emi_months", "0"); // Emi Months in case of EMI.
            chargingParams.Add("currency", "INR"); //INR is default.
            chargingParams.Add("ui_mode", "IFRAME"); //REDIRECT/IFRAME.
            chargingParams.Add("hash_method", "SHA256"); //MD5, SHA256
            chargingParams.Add("merchant_key_id", "payment"); //This is the default value.
            chargingParams.Add("timegmt", currentTime.ToString());
            chargingParams.Add("callback_url", "http://busnow.in/bus/default.aspx");
            chargingParams.Add("hash", GenHash(chargingParams));

            StringBuilder builder = new StringBuilder();
            foreach (var entry in chargingParams)
                builder.AppendFormat("{0}={1}&", entry.Key, entry.Value);

                <input type="submit" />
            <iframe width="500" height="500" src="<%=url %>"></iframe>
        var x = document.getElementById("__VIEWSTATE");


When you will Run you will get error message.

So first you have to register with PayZippy and get 

1. MID (merchant_id)
2. Secure key (used to determine hash)

3. Secure key id (merchant_key_id)

Then  place the value in the code and test :)

Enable PayPal IPN (Instant Payment Notifications)

Enable PayPal IPN (Instant Payment Notifications)

PayPal has many mechanism for making your site’s checkout experience more secure and a better experience for your users. Instant Payment Notifications helps by increasing both the security and usability of your checkout experience. IPN works by sending messages directly between PayPal and your site. Using this channel of communication, your site can automatically update when orders complete. Without IPN, orders can get lost due to user error. By enabling IPN, you give PayPal the ability to directly communicate with your site, making the checkout process easy and secure.
PayPal IPN is required for some features such as recurring payments.
Below are the instructions on how to enable IPN for your Vantage install:
Note: In order to use IPN, you will need a PayPal business account. Upgrading is easy and free. Just log into your PayPal account and click Upgrade.
  1. Log into your PayPal account
  2. Click My Account > Profile
  3. Click Selling Tools
  4. Under Selling Preferences, look for Instant Payment Notification Preferences
  5. Click Choose IPN Settings
  6. In another tab, open up your Vantage install and go to the PayPal Gateway Settings under the Payments > Setting page.
  7. Copy and Paste the Listener URL from the PayPal Gateway Settings into the Notification URL field on the Instant Payment Notification Preferences page on PayPal.com
  8. Press Save on PayPal.com
  9. Go back to your PayPal Gateway Settings, and check the Enable IPN box.
  10. Press Save. PayPal IPN is now enabled.
Notes for Return URL:
  • If any of your payment plans use recurring payments, this option must be checked. PayPal will be unable to communicate with your site otherwise.
  • If you have no other sites that use PDT, you can enter any URL into Return URL. Vantage controls the return URL and overrides any URL entered into Return URL. Regardless, we recommend entering your site’s root URL (IE: www.yoursite.com)
  • If you have another site that uses PDT, you should enter the return URL that you prefer for that site. Again, Vantage controls the return URL for your Vantage site and does not use the return URL provided on your PayPal account.
  • When PayPal IPN or PDT is enabled, the low-security validation mechanism used to validate non-IPN or non-PDT purchases will be disabled.
