  • Model deals with the business layer that is classes and the properties.
  • View is the part that deals with the display of data on the screen.
  • Controller interacts with the view and gets the user inputs from view.
  • Controller sends input to the model and in return, model sends output to the controller after performing actions.
  • Controller then displays the output on screen.
  • In traditional webform pattern code and design file is same and if we place the control on the design page that reflects in the code file also.
  • In Mvc design this file system is replaced.Here we put all the logic in one file called controller.From one controller we can call different UI.
  • In controller there is ActionResult that returns action against the ActionResult.
  • There is a view created against the ActionResult with the same name as the action result.
  • If we created the view against an ActionResult then in the Views folder a folder is created with the same name as of controller containing the views of that controller only.
Start by creating the project
  • Open the VS create new project,find ASP.NET MVC 4 Web Application.
     
    Open
     
  • After that a window appears select Internet Application and click OK.
     
    Internet Application
     
  • Mvc project will be created.
  • SolutionExplorer shows many folders.
     
    folders
     
  • Here in the solution explorer every folder has unique meaning.
  • Properties folder contains the version information and some other information about the project.
  • References store the refrence dlls required in the project.
  • App_Start contains the configuration files.
  • Content folder contain the css files.
  • Controllers folder contain the controllers for code.
  • Models folder contain the classes for buisness logics.
  • Scripts contain the javascript files.
  • Views folder contains views for the controllers.
Download CSS and JS files for bootstrap.
  • Go to the References folder right click on the folder >Find>Manage NuGet Packages>Click on the option.
  • Install bootstrap package.
     
    boostrap
     
  • Bootstrap is installed automatically and css files are saved in content folder and js files are saved in script folder.
Now register css and scripts for entire project.
  • Go to the App_Start folder > Open BundleConfig.cs,
  • Delete the code in the RegisterBundles method and replace with the given code.
    1. public class BundleConfig    
    2.    {    
    3.        public static void RegisterBundles(BundleCollection bundles)    
    4.        {    
    5.            StyleBundle(bundles);    
    6.            ScriptBundle(bundles);    
    7.        }    
    8.     
    9.        public static void StyleBundle(BundleCollection bundles)    
    10.        {    
    11.            bundles.Add(new StyleBundle("~/css")    
    12.                     .Include("~/Content/bootstrap.css"));    
    13.        }    
    14.     
    15.        public static void ScriptBundle(BundleCollection bundles)    
    16.        {    
    17.            bundles.Add(new ScriptBundle("~/js")    
    18.                     .Include("~/Scripts/jquery-{version}.js")    
    19.                     .Include("~/Scripts/bootstrap.js"));    
    20.        }    
    21.    }    
  • StyleBundle method register the css files.
  • ScriptBundle method register the js files.
  • Check the path of the files.
  • ~/css and ~/js are the root path for css and js files.
  • Call the both methods in the RegisterBundle method.
  • Check the path of the files carefully.
Now create the layout page for the entire project.
  • Go to the views folder find shared folder inside views folder.
  • Open _Layout.cshtml present in shared folder.
  • Write below given code,
    1. <!DOCTYPE html>

    65.     
    66.     @Scripts.Render("~/js")    
    67.     @RenderSection("scripts", required: false)    
    68. </body>

  • In the code given above we define the layout for entire project.
  • @Styles.Render("~/css") this is used to render the css files that included in the bundleConfig.cs file.
  • In the body tag nav bar is placed that is used to place the links for the page redirection.
  • This layout of bootstrap is fully responsive.
  • @RenderBody() is used to render the content on the page.
  • @Scripts.Render("~/js") include all the js files that included in the BundleConfig.cs file.
  • Now HomeController is created automatically inside the controllers folder.
  • View against the ActionResult is also created automatically.
  • Now inside the views folder find folder named Home ,find Index.cshtml view inside the Home folder.
