Learn 📖 Modal Popup Using MVC And Entity Framework In Depth

Introduction

In this article, we will learn to implement modal popup for CRUD operations using MVC and Entity Framework. This is a single page for multiple operations using jQuery AJAX.

Prerequisites

Visual Studio 2017
SQL Server

Note

Before going through this session, please visit my previous articles related to Angular 7 applications.

Step 1

Create three tables with the script as mentioned below.

USE [SatyaDB]
GO
/****** Object: Table [dbo].[Contacts] Script Date: 15-08-2019 21:35:17 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Contacts](
[ContactID] [int] IDENTITY(1,1) NOT NULL,
[ContactPerson] [varchar](100) NOT NULL,
[ContactNo] [varchar](20) NOT NULL,
[CountryID] [int] NOT NULL,
[StateID] [int] NOT NULL,
PRIMARY KEY CLUSTERED
(
[ContactID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
/****** Object: Table [dbo].[Country] Script Date: 15-08-2019 21:35:19 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[Country](
[CountryID] [int] IDENTITY(1,1) NOT NULL,
[CountryName] [varchar](100) NOT NULL,
PRIMARY KEY CLUSTERED
(
[CountryID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
/****** Object: Table [dbo].[State] Script Date: 15-08-2019 21:35:19 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[State](
[StateID] [int] IDENTITY(1,1) NOT NULL,
[CountryID] [int] NOT NULL,
[StateName] [varchar](100) NOT NULL,
PRIMARY KEY CLUSTERED
(
[StateID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

Step 2

Enter some records to test it in the browser including the country and state table. I have implemented cascading dropdown method using country and state table in this application.

INSERT [dbo].[State] ([StateID], [CountryID], [StateName]) VALUES (165, 4, N'Nagaland')
GO
SET IDENTITY_INSERT [dbo].[State] OFF
GO

Step 3

In this step, I have added an entity data model named "SatyaModalEntity.edmx". Follow the steps,

Go to Solution Explorer > right-click on the project name from Solution Explorer.

Go to Add > New item > select ADO.NET Entity Data Model under data.

Enter the model name > Add.

A popup window will appear (Entity Data Model Wizard).

Select "Generate from database" > Next.

Chose your data connection > select your database > Next.

Select tables > enter Model Namespace > Finish.

Step 4

In this step, I have created a partial class for implementing two fields - CountryName and StateName. Here, I have also added a Metadata class for applying validation on the Contact model.

Code

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;
namespace MVCModalApp
{
[MetadataType(typeof(ContactMetaData))]
public partial class Contact
{
public string CountryName { get; set; }
public string StateName { get; set; }
}
public class ContactMetaData
{
[Required(ErrorMessage = "Contact Name required", AllowEmptyStrings = false)]
[Display(Name = "Contact Person")]
public string ContactPerson { get; set; }
[Required(ErrorMessage = "Contact No required", AllowEmptyStrings = false)]
[Display(Name = "Contact No")]
public string ContactNo { get; set; }
[Required(ErrorMessage = "Country required")]
[Display(Name = "Country")]
public int CountryID { get; set; }
[Required(ErrorMessage = "State required")]
[Display(Name = "State")]
public int StateID { get; set; }
}
}

Step 5

In this step, I have added a JavaScript file named "Satya.CRUDContacts.js" under scripts folder for opening the popup to create a new contact and to read, update, and delete existing records.

Code Ref

var $dialog;
$(document).ready(function () {
//Populate Contact
LoadContacts();
//Open popup
$('body').on("click", "a.popup", function (e) {
e.preventDefault();
var page = $(this).attr('href');
OpenPopup(page);
});
$('body').on('change', '#CountryID', function () {
var countryID = $(this).val();
LoadStates(countryID);
});
//Save Contacts
$("body").on('submit', '#saveForm', function (e) {
e.preventDefault();
SaveContacts();
});
//Update Contacts
$("body").on('submit', '#updateForm', function (e) {
e.preventDefault();
UpdateContacts();
});
//Delete Contact
$('body').on('submit', '#deleteForm', function (e) {
e.preventDefault();
DeleteContact();
});
});
function LoadContacts() {
$('#update_panel').html('Loading Data...');
$.ajax({
url: '/home/GetContacts',
type: 'GET',
dataType: 'json',
success: function (d) {
if (d.length > 0) {
var $data = $('<table></table>').addClass('table table-responsive table-striped');
var header = "<thead><tr><th style='background-color: Yellow; color: blue'>Contact Person</th><th style='background-color: Yellow; color: blue'>Contact No</th><th style='background-color: Yellow; color: blue'>Country</th><th style='background-color: Yellow; color: blue'>State</th><th style='background-color: Yellow; color: blue'>Action</th></tr></thead>";
$data.append(header);
$.each(d, function (i, row) {
var $row = $('<tr/>');
$row.append($('<td/>').html(row.ContactPerson));

Step 7

Here, I have added the code inside index.cshtml for showing employee details.

Code

@{
ViewBag.Title = "List Of Employees";

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css" />
<style>
/*This is optional, I have added this for make looks good*/
table {

text-align: left;
padding: 8px;
}
tr:nth-child(even) {

Step 8

In this step, I added a partial view named "Save.cshtml" for the "Save" Action & design.

Right-click on Shared folder (under Views) > Add > View... > Enter View Name > Select Template as Edit > Select your model class "Contact (MVCModalApp)" > Check "Create as a Partial View" > Add.

Code

@model MVCModalApp.Contact
<h2>Save Employee Details</h2>
@using (Html.BeginForm("Save", "Home", FormMethod.Post, new { role = "form", id = "saveForm" }))
{
@*here role = "form" for bootstrap design (optional) *@
@Html.ValidationSummary(true)
@Html.AntiForgeryToken()
@*here the field for person name *@
<div class="form-group">
@Html.HiddenFor(model => model.ContactID)
@Html.LabelFor(model => model.ContactPerson)
@Html.TextBoxFor(model => model.ContactPerson, new { @class = "form-control" })
</div>
@*here the field for person number *@
<div class="form-group">
@Html.LabelFor(model => model.ContactNo)
@Html.TextBoxFor(model => model.ContactNo, new { @class = "form-control" })

<div id="msg"></div>
}

Step 9

In this step, I added a partial view named "Update.cshtml" for the "Update" Action & design.

Right Click on Shared folder (under Views) > Add > View... > Enter View Name > Select Template as Edit > Select your model class "Contact (MVCModalApp)" > Check "Create as a Partial View" > Add.

Code

@model MVCModalApp.Contact
<h2>Update Employee Details</h2>
@using (Html.BeginForm("Update", "Home", FormMethod.Post, new { role = "form", id = "updateForm" }))
{
@*here role = "form" for bootstrap design (optional) *@
@Html.ValidationSummary(true)
@Html.AntiForgeryToken()
@*here the field for person name *@

OK, I see, it appends Entities to your db name that's where SatyaDBEntities come from. Table is generated. Excellent. But when I click Edit or Delete nothing happens, no popup. Debugging produces Object doesn't support property or method 'dialog' in the OpenPopup function in Satya.CRUDContacts.js. Thank You.
