Today, we will learn about integrating a theme in ASP.NET MVC application. As every developer prefer to use a theme for the frontend for his/her application. Themes are available at free of cost or paid which depends on the feature for the theme.Here, we will see how can we integrate the AdminLTE theme in our MVC application. It is a free theme and very popular among developers due to its outstanding layouts. You can see the documentation of AdminLTE from here

Download the theme and put the bower_component and plugins in one folder as it contains the JS files so we will put them in one folder in Script -> adminlte

Make another folder in Content -> adminlte and put the files of dist folder in it.

Add the Helpers folders and make a cs file named HTMLHelperExtensions.cs and add the code in it. This will be used in our _SideBar.cshtml which will we make later

using System;
using System.Web.Mvc;

namespace adminlte
{
    public static class HTMLHelperExtensions
    {
        public static string IsSelected(this HtmlHelper html, string controller = null, string action = null, string cssClass = null)
        {

            if (String.IsNullOrEmpty(cssClass))
                cssClass = "active";

            string currentAction = (string)html.ViewContext.RouteData.Values["action"];
            string currentController = (string)html.ViewContext.RouteData.Values["controller"];

            if (String.IsNullOrEmpty(controller))
                controller = currentController;

            if (String.IsNullOrEmpty(action))
                action = currentAction;

            return controller == currentController && action == currentAction ?
                cssClass : String.Empty;
        }

        public static string PageClass(this HtmlHelper html)
        {
            string currentAction = (string)html.ViewContext.RouteData.Values["action"];
            return currentAction;
        }

    }
}

So our folder structure will look like this.

Open the RouteConfig.cs file and change the routing configurations.

public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Dashboard", action = "Dashboardv1", id = UrlParameter.Optional }
            );
        }
    }

Now we will make the basic structure for the theme like Sidebar, Header, Footer, etc.

Navigate to View -> Shared and add the following files in it. Remember all the files in Shared folder are partial view. If you do not have an idea about partial view then you can refer our article on Partial View from here

Open the _Aside.cshtml file and add the code in it.

    <!-- Control Sidebar -->
<aside class="control-sidebar control-sidebar-dark">
    <!-- Create the tabs -->
    <ul class="nav nav-tabs nav-justified control-sidebar-tabs">
        <li><a href="#control-sidebar-home-tab" data-toggle="tab"><i class="fa fa-home"></i></a></li>
        <li><a href="#control-sidebar-settings-tab" data-toggle="tab"><i class="fa fa-gears"></i></a></li>
    </ul>
    <!-- Tab panes -->

Now finally the _Layout.cshtml file

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <!-- Tell the browser to be responsive to screen width -->
    <meta content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" name="viewport">

    @Styles.Render("~/Content/css")

    <!-- Google Font -->
    <link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Source+Sans+Pro:300,400,600,700,300italic,400italic,600italic">
    @if (IsSectionDefined("Styles"))
    {@RenderSection("Styles", required: false)}
</head>
<body class="hold-transition skin-blue sidebar-mini">

    <div class="wrapper">

        @Html.Partial("_Header")

        @Html.Partial("_Sidebar")

                @RenderBody()

        @Html.Partial("_Footer")

        @Html.Partial("_Aside")
        <!-- Add the sidebar's background. This div must be placed
        immediately after the control sidebar -->
        <div class="control-sidebar-bg"></div>
    </div>




    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/lib")
    @RenderSection("scripts", required: false)
</body>
</html>

Now when we run it our theme will look like this.

theme-integration-in-asp-net-3

Now I will only show you one Controller and one cshtml file and for rest of you can follow the same procedure.

Add the Tables controller and add the code in it.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace adminlte.Controllers
{
    public class TablesController : Controller
    {
        // GET: Tables
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult Data()
        {
            return View();
        }

        public ActionResult Simple()
        {
            return View();
        }
    }
}

Generate the View for each ActionMethod.

Navigate to View -> tables -> Simple.cshtml and add the code in it.

@{
    ViewBag.Title = "Simple";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

  <!-- Content Wrapper. Contains page content -->
<div class="content-wrapper">
    <!-- Content Header (Page header) -->
    <section class="content-header">
