[quads id=RndAds] ASP.NET CORE Mvc - View ModelAs of now we have discussed different data passing techniques between controllers to view that is  ViewData, ViewBag and Strongly typed model In this tutorial will discuss about the ViewModel.ViewmodelViewmodel is a class which works similar to the Strongly Typed Model.A ViewModel in ASP.NET CORE MVC application is a model which has more than one model data required for a particular view and this is called a ViewModel in  MVC.Let's take an example, as of now we have displayed the student information and in our application and now we want to display the address details of the particular. In this case we require the Student model and Address Model where the student model stores the student data and address model holds the address…

[quads id=RndAds] ASP.NET CORE Mvc Strongly Typed ViewIn this tutorial will discuss strongly typed view in asp.net core mvc. strongly typed view in mvc is another data passing technique from controller to view.Strongly Type ViewThe view which binds to a specific type of ViewModel is called as Strongly Typed View. By specifying  the model, once we define the  the Visual studio provides the intellisense and compile time checking of type.Strongly Type View ConfigurationThe strongly typed Views are created using the @model directive and we need to pass the model object as a parameter to the View() extension method.  The Controller base class provides us the following two overloaded versions of View()  extension method which we can use to pass the model object from the controller action method to a view.public virtual ViewResult…

[quads id=RndAds] ASP.NET CORE MVC ViewBag and ViewDataIn this tutorial we will discuss how to pass data from the Controller to the view using ViewData and ViewBag. we will also discuss the difference between ViewData and ViewBag.ViewDataThe ViewData in MVC is a dictionary of weakly typed objects which is derived from the ViewDataDictionary class.public ViewDataDictionary ViewData { get; set; }ViewData does not provide compile time error checking. For example, if you mis-spell the key names you wouldn't get any compile time error. You get to know about the error only at runtime.The ViewData only transfers the data from the controller action method to a view, but not vice-versa. That means it is valid only during the current request.In our example, we want to pass student information to the view from…

[quads id=RndAds] ASP.NET CORE Mvc ViewsIn this tutorial will discuss on views in asp.net core mvc and understand different ways of returning view.Views in MVCA view is an HTML template with embedded Razor markup which use to represent data.A view is used to display data using the model class object.A view file has .cshtml extension as we using the programming language is C# in our ASP.NET Core MVC applicationView Files Location.In MVC view files are located in the Views folder.View files of the specific controller are stored under a sub-folder in the Views folder and that sub-folder has the same name as the controller.In our application, We have two controllers HomeController and StudentController. We have one action on each controller as of now. We will be modifying going forward as…

[quads id=RndAds] ASP.NET CORE Mvc ControllersIn this tutorial will discuss what is a controller in asp.net core mvc and role of controller in asp.net core mvc The Controllers in ASP.NET Core MVC application are the classes and its derived from the base class  System.Web.Mvc.ControllerController class having a variety of public methods. These public methods are called as actions (action methods) in the Controller class.These action methods are the methods of a Controller which is actually going to handle the incoming HTTP Requests.The controller class name must be suffixed with word "Controller". For example HomeController, StudentController. If you have not gave suffix then it will throw error of resource not found.A controller is used to define and group a set of actions. An action (or action method) is a method on a…

[quads id=RndAds] ASP.NET CORE MVC ModelIn this tutorial will discuss and understand models in asp.net core mvc. what is purpose of model and how to add models in asp.net core mvc.The Model in asp.net core MVC nothing but the class. The model does NOT depend on the controller or the view.The Model  is the representation of the data being posted to the Controller, the data being worked on in a View or the representation of the domain specific entities operating in the business tier.The Model contains core application information. It includes data, validation rules, data access, and aggregation logic.The Model is known as domain object or domain entity which implements domain logic. In simple terms, this logic is used to handle the data passed between the database and the user…

[quads id=RndAds] ASP.NET CORE AddMVC Vs AddMVCCore (Bootrapping ways)In this tutorial we will discuss the difference between AddMvc() and AddMvcCore() vs AddControllersWithViews() vs AddControllers() vs AddRazorPages() While working on empty asp.net core web application template the first question comes to mind is Which method should we use to configure our application in ConfigureServices method of startup classThere are several ways of bootstrapping your MVC applications on top of ASP.NET Core 3.x.  Depending on your requirement is your choice to choose the correct one such as  controllers, views, pages and expose them as HTTP endpoints.In .NET Core 2.x and earlier, you could register the MVC framework in the ASP.NET Core dependency injection container in two ways:services.AddMvc()services.AddMvcCore()In ASP.NET Core 3.x and above version added another three additional ways: services.AddControllers()services.AddControllersWithViews()services.AddRazorPages()AddMvcCore()The AddMvcCore() method adds only…

[quads id=RndAds] ASP.NET CORE Setup MVCIn this tutorials we will discuss, setting up MVC in ASP.NET Core application. Will see demonstration from creating empty project and setup MVC into the request pipeline.Setup mvc in asp.net core 3.1 with empty project.Open visual studio 2019 and select Create new project.2. On the Create new project window select asp.net core web application and click on the next button.3.On next click you will get the configure project screen to provide project name and path.4. On the next screen choose the version of project and from below option choose empty and click. 5. Lets add dependency in to ConfigureService method in Startup.cs class file to enable mvc as services.AddMVC()6. Let's modify the Configure method and make changes in app.UseEndpoints as below.app.UseEndpoints(endpoints =>  {          endpoints.MapControllerRoute(                     name: "default",  …

[quads id=RndAds] ASP.NET CORE MVC ArchitectureIn this tutorial will discuss what is mvc and architecture of mvc.MVCThe Model-View-Controller (MVC) architectural pattern separates an application into three main components: Models, Views, and Controllers. This pattern helps to achieve separation of concerns. Almost all the languages use MVC with slight variation, but conceptually it remains the same.Using this pattern, user requests are routed to a Controller which is responsible for working with the Model to perform user actions and/or retrieve results of queries. The Controller chooses the View to display to the user, and provides it with any Model data it requires.ModelThe Model in an MVC application represents the state of the application and any business logic or operations that should be performed by it. A model can also contain the logic…
