In this article, we are going to learn how to insert a record into the database using ASP.NET MVC with Web API.


ASP.NET Web API (Application Programming Interface) is a framework for building Web APIs on top of the .NET Framework. In this article, we shall learn how to insert a record into database using ASP.NET MVC with Web API.


Here following assumptions are made
  1. Reader has good knowledge of jQuery and jQuery javascript file has been referenced on the page
  2. Reader has good knowledge of ASP.NET MVC

Using the code

My ASP.NET MVC model structure looks like below assuming the database table name is "PersonalDetails".

public class PersonalDetails
        public int AutoId { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public int Age { get; set; }
        public bool Active { get; set; }
Based on above mode, we have created a view ASP.NET MVC view and below is the code for that. In this we have created three textboxes, one dropdown and a button.
    <label>First Name</label>
    <label>Last Name</label>
    @Html.DropDownList("Active", new List<SelectListItem>
        new SelectListItem {Text = "Yes", Value = "true", Selected = true},
        new SelectListItem {Text = "No", Value = "false"},
    }, "Select ...")
    <button id="btnAdd">Add</button> 
    @Html.ActionLink("Back to List", "ListRecords")
Clicking on the button fires up a JavaScript function and below is the code for that.

<script type="text/javascript">

    $("#btnAdd").click(function () {

        var PersonalDetails = {
            "FirstName": $("#FirstName").val(),
            "LastName": $("#LastName").val(),
            "Age": $("#Age").val(),
            "Active": $("#Active").val()
            type: "POST",
            url: 'http://localhost:28206/api/PersonalDetails/PostPersonalDetails',
            data: JSON.stringify(PersonalDetails),
            contentType: "application/json;charset=utf-8",
            processData: true,
            success: function (data, status, xhr) {
                alert("The result is : " + status);
            error: function (xhr) {
In the above function, we are first creating a prototype (like a class object) of JavaScript and setting its properties values matching with the ASP.NET MVC model.

Then we are using $.ajax post method to submit the data on the API controller. Here is the code for the ASP.NET MVC API Controller. Please note that it is not normal ASP.NET MVC Controller but ApiController.

 public class PersonalDetailsController : ApiController
        private MVCWebAPIContext db = new MVCWebAPIContext();
        public IHttpActionResult PostPersonalDetails([FromBody] PersonalDetails personaldetails)
            if (!ModelState.IsValid)
                return BadRequest(ModelState);


            return CreatedAtRoute("DefaultApi", new { id = personaldetails.AutoId }, personaldetails);
When the Add button is clicked, ajax request goes to above PostPersonalDetails action method and the JavaScript prototype PersonalDetails object is converted to the ASP.NET MVC PersonalDetails model and record has been inserted into the database using Entity Framework.

After a record is inserted, user gets an alert box with success message otherwise $.ajax error function fires and gives error response.


Please note that $.ajax POST method doesn't work in the latest version of Internet Explorer (IE) browser. To make this work in IE, please visit Solution - jQuery post doesn't work in Internet Explorer (IE) post.

Hope this article will be helpful for someone.
