Introduction
This article will explain how to create bootstrap pagination dynamically in ASP.Net MVC. I will explain it with an example from an SQL database. Before understanding this article you should have a basic understanding of the following:
- Bootstrap 4
- MVC
- Entity Framework
- View Model
- SQL Server
Step 1. Open your favorite SQL server database, any version. It doesn’t matter. Create the table's frontend and backend technology.
CREATE TABLE [dbo].[Blog](
[Id] [int] IDENTITY(1,1) NOT NULL,
NULL,
[Url] [nvarchar](max) NULL,
[Date] [datetime] NULL,
CONSTRAINT [PK_Blog] PRIMARY KEY CLUSTERED
(
[Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
Step 2. Now open Visual Studio 2017 or any version you wish.
Step 3. Create an empty project in Visual Studio, and give it an appropriate name. Checked the MVC checkbox and clicked on OK.
Step 4. Right-click on the Models folder and add a database model. Add Entity Framework now. For that, right-click on the Models folder, select Add, then select New Item.
You will get a window; from there, select Data from the left panel and choose ADO.NET Entity Data Model, give it the name MyModel (this name is not mandatory, you can give any name), and click "Add"
After you click on "Add a window", the wizard will open. Choose EF Designer from the database and click "Next".
After clicking on "Next", a window will appear. Choose New Connection. Another window will appear. Add your server name - if it is local, then enter a dot (.). Choose your database and click "OK".
The connection will be added. If you wish, save the connection name as you want. You can change the name of your connection below. It will save the connection in the web config. Now, click "Next".
After clicking on NEXT, another window will appear. Choose the database table name as shown in the below screenshot and click "Finish".
Entity Framework gets added and the respective class gets generated under the Models folder.
Step 5. Right-click on the Controllers folder to add a controller.
A window will appear. Choose MVC5 Controller-Empty and click "Add".
After clicking on "Add", another window will appear with DefaultController. Change the name to HomeController and click "Add". The HomeController will be added under the Controllers folder. Don’t change the Controller suffix for all controllers, change only the highlight, and instead of Default, just change Home.
Step 6. Right, click on the project “Add Folder” and name it ViewModel. Now right-click on this folder and “Add Class” with the name BlogViewModel.
using MvcBootstrapPaginationDynamic_Demo.Models;
using System;
using System.Collections.Generic;
using System.Linq;
namespace MvcBootstrapPaginationDynamic_Demo.ViewModel
{
public class BlogViewModel
{
public IEnumerable<Blog> Blogs { get; set; }
public int BlogPerPage { get; set; }
public int CurrentPage { get; set; }
public int PageCount()
{
return Convert.ToInt32(Math.Ceiling(Blogs.Count() / (double)BlogPerPage));
}
public IEnumerable<Blog> PaginatedBlogs()
{
int start = (CurrentPage - 1) * BlogPerPage;
return Blogs.OrderBy(b => b.Id).Skip(start).Take(BlogPerPage);
}
}
}
Controller Class Code
using MvcBootstrapPaginationDynamic_Demo.Models;
using MvcBootstrapPaginationDynamic_Demo.ViewModel;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MvcBootstrapPaginationDynamic_Demo.Controllers
{
public class HomeController : Controller
{
private readonly MvcDemoContext db = new MvcDemoContext();
public ActionResult Index(int page = 1)
{
var blogsView = new BlogViewModel
{
BlogPerPage = 5,
Blogs = db.Blogs.OrderBy(d => d.Date),
CurrentPage = page
};
return View(blogsView);
}
}
}
Step 7. Right-click on the Index action method in the controller class “Add View”
Index View Code
@model MvcBootstrapPaginationDynamic_Demo.ViewModel.BlogViewModel
@{
ViewBag.Title = "Index";
}
<h3 class="text-uppercase">List of Blogs</h3>
@foreach (var blog in Model.PaginatedBlogs())
{
<div class="alert alert-secondary rounded-0">
<a href="@blog.Url" class="link" target="_blank">@blog.title</a>
<span class="pull-right text-primary"><i class="fa fa-calendar"></i> @blog.Date.Value.ToString("dd-MM-yyyy")</span>
</div>
}
<ul class="pagination">
@for (int i = 1; i <= Model.PageCount(); i++)
{
<li class="@(i == Model.CurrentPage ? "page-item active" : "page-item")">
<a class="page-link" href="@Url.Action("Index", new { page = i })">@i</a>
</li>
}
</ul>
Step 8. Install the latest version of Bootstrap and JQuery from the NuGet package manager under the tool in Visual Studio.
Step 9. Build your project and Run by pressing Ctrl+F5
