The View component supports as a user interface that helps in displaying the segment in the data using the model and enables data modification.
The Controller component handles the request made by the user at different intervals.
In this article, you can go through the set of MVC interview questions most frequently asked in the interview panel. This will help you crack the interview as the topmost industry experts curate these at HKR training.
Let us have a quick review of the MVC interview questions.
Ans: The following are the steps which must be applied for creating the request object.
Ans: The MVC Routing uses URL in ASP.NET MVC framework which maps action methods and controllers instead of applying physical files into the system. The routing engine is used for developing appropriate routes for the movement of information and to handle different kinds of requests, which later passes through Routing Engines, Routes, and reaches Controller.
Ans: MVC routes are accountable for governing which controller method will be executed for a given URL. The URL comprises the following properties.
Ans: The various return types of a controller action in MVC are.
Ans: There are three possible ways of maintaining a session in MVC.
Ans: Action filters are used where there is a scenario where you need to implement some logic prior to the execution of an action method or right after it. These filters are used in determining the logic necessary for executing before or after the execution methods gets executed. The action filters are used as attributes by action methods. Different types of MVC action filters are.
Ans: The errors are handled by the concept of exception handling either it is a windows form or even a web application. The HandlerError attribute helps in providing the built-in exception filters. The HandleError attribute of ASP.NET is functional over the action method as well as Controller at its global level.
public static void RegGlobalFilters(Global_FilterCollection filt)
protected void Application_Start()
Ans: It is a java framework used for creating web applications. Spring MVC follows the MVC design patterns which use the basic features of a core spring framework including the dependency injection, inversion of control etc.
Ans: It is a framework for a web application which is testable and is light weighted. ASP.NET MVC helps in separating different components of MVC application into Model, View, and Controller.
Ans: Razor is a new view engine introduced by MVC3. It acts as pluggable modules and applies different template syntax options.
Ans: ViewStart is a new layout introduced by the razor engine which is automatically applied for all views. It is executed at the very beginning followed by the start rendering as well as other views.
Layout = "~/ Views/ Shared/ _
<meta name="viewport" />
<title> InitialView </title> </head>
Ans: The different file extensions used for razor views are
Ans: The partial view in MVC is referred to as the chunk of HTML that is applied in the current DOM used to componentize Razor views and create and update them at regular intervals. If a URL returns from the partial view gets invoked from the address bar, then, in such case, an incomplete page is displayed with a missing title, style sheets, and script.
Ans: It is the action link that helps in navigating from one view to another by using a hyperlink. It creates a simple URL and navigates to the “Home” controller and also generates the “Gotohome” action.
Ans: The different stages are of MVC Page life cycle are.
Ans: The primary rules for creating Razor are.
Ans: The two different approaches of adding constraints to an MVC route are.
Ans: In order to include a security layer to access the user for a specific service the authentication forms are added. This authentication verifies the user’s identity through the credentials such as username with password or email with a password.
The sample code snippet:
<authentication mode = "Forms" >

Ans: It is defined as an ASP.NET’s code-generation framework used in web applications to develop the MVC applications for those who want to rapidly enhance the code that intermingles with the application’s data model. Scaffolding can also reduce the quantity of time to develop a standard data operation in the application.
Ans: The scaffold templates include page templates, field page templates, filter templates, and entity page templates. These templates support the building of a functional data-driven website.
Ans: With the use of validators you can able to implement the validation in MVC. The validators are well defined in the System.ComponentModel.DataAnnotations namespace.
Ans: The different validators available in ASP.NET are.
