How to insert multiple row to database using asp.net MVC

Step - 1: Create New Project.

Go to File > New > Project > Select asp.net MVC4 web application > Entry Application Name > Click OK > Select Internet Application > Select view engine Razor > OK

Step-2: Add a Database.

Go to Solution Explorer > Right Click on App_Data folder > Add > New item > Select SQL Server Database Under Data > Enter Database name > Add.

Step-3: Create table for save data.

Open Database > Right Click on Table > Add New Table > Add Columns > Save > Enter table name > Ok.

In this example, I have used one table as below

Step-4: Add Entity Data Model.

Go to Solution Explorer > Right Click on Project name form Solution Explorer > Add > New item > Select ADO.net Entity Data Model under data > Enter model name > Add.
A popup window will come (Entity Data Model Wizard) > Select Generate from database > Next >

Chose your data connection > select your database > next > Select tables > enter Model Namespace > Finish.

Step-5: Apply Validation On Model.

Open your model and add validation. Please follow below code

namespace MVCAjaxSave
{
    using System;
    using System.Collections.Generic;
    using System.ComponentModel.DataAnnotations;
    public partial class ContactInfo
    {
        public int ID { get; set; }
        [Required(ErrorMessage = "Contact Name required!", AllowEmptyStrings = false)]
        public string ContactName { get; set; }
        [Required(ErrorMessage = "Contact No required!", AllowEmptyStrings = false)]
        public string ContactNo { get; set; }
    }
}

Step-6: Add a new Controller.

Go to Solution Explorer > Right Click on Controllers folder form Solution Explorer > Add > Controller > Enter Controller name > Select Templete "empty MVC Controller"> Add.

Step-7: Add new action into your controller for save data.

Here I have added "BulkData" Action into "Save" Controller. Please write this following code

public ActionResult BulkData()
{
    // This is only for show by default one row for insert data to the database
    List<ContactInfo> ci = new List<ContactInfo> {new ContactInfo{ ID = 0, ContactName = "", ContactNo=""} };
    return View(ci);
}

Step-8: Add view for the Action & design.

Right Click on Action Method (here right click on form action) > Add View... > Enter View Name > Select View Engine (Razor) > Check "Create a strong-typed view" > Select your model class > Add.
[N:B:Please Rebuild solution before add view.] 

Step-9: Add jquery code for save data to the server.

Jquery Code 

@section Scripts{
    @Scripts.Render("~/bundles/jqueryval")
    <script language="javascript">
        $(document).ready(function () {
 
            //1. Add new row
            $("#addNew").click(function (e) {
                e.preventDefault();
                var $tableBody = $("#dataTable");
                var $trLast = $tableBody.find("tr:last");
                var $trNew = $trLast.clone();
 
                var suffix = $trNew.find(':input:first').attr('name').match(/\d+/);
                $trNew.find("td:last").html('<a href="#" class="remove">Remove</a>');
                $.each($trNew.find(':input'), function (i, val) {
                    // Replaced Name
                    var oldN = $(this).attr('name');
                    var newN = oldN.replace('[' + suffix + ']', '[' + (parseInt(suffix) + 1) + ']');
                    $(this).attr('name', newN);
                    //Replaced value
                    var type = $(this).attr('type');
                    if (type.toLowerCase() == "text") {
                        $(this).attr('value', '');
                    }
 
                    // If you have another Type then replace with default value
                    $(this).removeClass("input-validation-error");
 
                });
                $trLast.after($trNew);
 
                // Re-assign Validation 
                var form = $("form")
                    .removeData("validator")
                    .removeData("unobtrusiveValidation");
                $.validator.unobtrusive.parse(form);
            });
 
            // 2. Remove 
            $('a.remove').live("click", function (e) {
                e.preventDefault();
                $(this).parent().parent().remove();
            });
 
        });
    </script>
}

Complete View 

@model List<MVCBulkInsert.ContactInfo>
@{
    ViewBag.Title = "Insert Bulk Data";
}
<style>
    td {
    padding:5px;
}
</style>
<div style="width:700px; padding:5px; background-color:white;">
    @using (Html.BeginForm("BulkData","Save", FormMethod.Post))
    {
        @Html.AntiForgeryToken()
        @Html.ValidationSummary(true)
        
        if (ViewBag.Message != null)
        {
            <div style="border:solid 1px green">
                @ViewBag.Message
            </div>
        }
        
        <div><a href="#" id="addNew">Add New</a></div>
        <table id="dataTable" border="0" cellpadding="0" cellspacing="0">
            <tr>
                <th>Contact Name</th>
                <th>Contact No</th>
                <th></th>
            </tr>
            @if (Model != null && Model.Count > 0)
            {
                int j = 0;
                foreach (var i in Model)
                {
                    <tr style="border:1px solid black">
                        <td>@Html.TextBoxFor(a=>a[j].ContactName)</td>
                        <td>@Html.TextBoxFor(a=>a[j].ContactNo)</td>
                        <td>
                            @if (j > 0)
                            {
                                <a href="#" class="remove">Remove</a>
                            }
                        </td>
                    </tr>
                    j++;
                }
            }
        </table>
        <input type="submit" value="Save Bulk Data" />
    }
</div>
 
@* Here I will add Jquery Code for validation / dynamically add new rows / Remove rows etc *@
 
@section Scripts{
    @Scripts.Render("~/bundles/jqueryval")
    <script language="javascript">
        $(document).ready(function () {
 
            //1. Add new row
            $("#addNew").click(function (e) {
                e.preventDefault();
                var $tableBody = $("#dataTable");
                var $trLast = $tableBody.find("tr:last");
                var $trNew = $trLast.clone();
 
                var suffix = $trNew.find(':input:first').attr('name').match(/\d+/);
                $trNew.find("td:last").html('<a href="#" class="remove">Remove</a>');
                $.each($trNew.find(':input'), function (i, val) {
                    // Replaced Name
                    var oldN = $(this).attr('name');
                    var newN = oldN.replace('[' + suffix + ']', '[' + (parseInt(suffix) + 1) + ']');
                    $(this).attr('name', newN);
                    //Replaced value
                    var type = $(this).attr('type');
                    if (type.toLowerCase() == "text") {
                        $(this).attr('value', '');
                    }
 
                    // If you have another Type then replace with default value
                    $(this).removeClass("input-validation-error");
 
                });
                $trLast.after($trNew);
 
                // Re-assign Validation 
                var form = $("form")
                    .removeData("validator")
                    .removeData("unobtrusiveValidation");
                $.validator.unobtrusive.parse(form);
            });
 
            // 2. Remove 
            $('a.remove').live("click", function (e) {
                e.preventDefault();
                $(this).parent().parent().remove();
            });
 
        });
    </script>
}

Step-10: Add another action into your controller for Save Data to the server.

Here I have added "BulkData" Action into "Save" Controller for POST Action. Please write this following code

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult BulkData(List<ContactInfo> ci)
{
    if (ModelState.IsValid)
    {
        using (MyDatabaseEntities dc = new MyDatabaseEntities())
        {
            foreach (var i in ci)
            {
                dc.ContactInfoes.Add(i);
            }
            dc.SaveChanges();
            ViewBag.Message = "Data successfully saved!";
            ModelState.Clear();
            ci = new List<ContactInfo> { new ContactInfo{ ID = 0, ContactName = "", ContactNo= ""} };
        }
    }
    return View(ci);
}

Step-11: Run Application.
