NET MVC is one of the most popular development frameworks for Web applications. In this article, I'll list top MVC Interview Questions. MVC Interview questions and answers PDF - Free download as PDF File .pdf), Why razor when we already had ASPX? So which is a better fit Razor or ASPX?. NET MVC Interview Questions have been designed specially to get and what you answer: Breifly explain us what is MVC? MVC is a pattern.

TempData is again a key, value pair as ViewData. TempData is used when the data is to be used in two consecutive requests, this could be between the actions or between the controllers. This requires typecasting in view. This method is used to render the specified partial view as an HTML string. This method does not depend on any action methods.

Will it affect the app? You will face performance problems and unless you already know this, it will be difficult to track down the reason. How would you achieve that? NET session state and support running across several servers. What additional configuration can you perform without writing custom code?

What are your steps? NET Core is a new platform and supports several approaches. The candidate has to stress that, in the project, we need to use some kind of distributed cache—for example, Redis.

What are the different types of results in MVC? Can we create our custom view engine using MVC? What is WebAPI? What is MVC Model view controller? MVC is architectural pattern which separates the representation and the user interaction. Its divided in three broader sections, Model, View and Controller.

Below is how each one of them handles the task. The View is responsible for look and feel. Model represents the real world object and provides data to the View.

The Controller is responsible to take the end user request and load the appropriate Model and View. Below are the steps how control flows in MVC Model, view and controller architecture:- All end user requests are first sent to the controller.

The controller depending on the request decides which model to load. The controller loads the model and attaches the model with the appropriate view. The final view is then attached with the model data and sent as a response to the end user on the browser. MVC architecture is suited for web application than windows. For window application MVP i.

Model view presenter is more applicable. There are two big benefits of MVC:Separation of concerns is achieved as we are moving the code behind to a separate class file. By moving the binding code to a separate class file we can reuse the code to a great extent. Automated UI testing is possible because now the behind code UI interaction code has moved to a simple.

NET class. This gives us opportunity to write unit tests and automate manual testing. MVC is an evolution of a 3 layered traditional architecture. Many components of 3 layered architecture are part of MVC.

So below is how the mapping goes. User interface. Middle layer User interface Data access layer. Model view controller architecture View. Controller Model. Data access layer.

So I have highlighted important differences which you can run through before the interviewer. This is defined by adding an entry in to the routes collection using the maproute function. For windows authentication you need to go and modify the web. Below is the code snippet for the same. Now only the users specified in the controller and action can access the same.

Forms authentication is implemented the same way as we do in ASP. So the first step is to set authentication mode equal to forms. The loginUrl points to a controller here rather than page. If the user is proper we will set the cookie value. Ajax libraries Jquery Below is a simple sample of how to implement Ajax by using Ajax helper library. In the below code you can see we have a simple form which is created by using Ajax.

BeginForm syntax. This form calls a controller action called as getCustomer. So now the submit action click will be an asynchronous ajax call. ActionLink function as shown in the below code. So if you want to create Ajax asynchronous hyperlink by name GetDate which calls the GetDate function on the controller , below is the code for the same.

You can see how GetDate function has a pause of 10 seconds. Sleep ; returnDateTime. All this logic is put in to a function called as GetData and you can make a call to the GetData function on a button or a hyper link click event as you want.

ActionResult can be used to exploit polymorphism and dynamism. So if you are returning different types of view dynamically ActionResult is the best thing.

For example in the below code snippet you can see we have a simple action called as DynamicView. Belowisadetailedlist foryourinterest. There 12 kinds of results in MVC, at the top is ActionResultclass which is a base class that canhave11subtypessas listed below: ContentResult - Writes content to the response stream without requiring a view 9.

FileContentResult - Returns a file to the client FileStreamResult - Returns a file to the client, which is provided by a Stream FilePathResult - Returns a file to the client. Implement post-processinglogicbeforethe action happens.

Cancel a current execution. Inspect the returned value. Provide extra data to the action. Inline action filter. Creating an ActionFilter attribute. To create a inline action attribute we need to implement IActionFilter interface. We can implement pre-processing logic or cancellation logic in these methods.

To create an action filter attribute we need to inherit from ActionFilterAttribute and implement IActionFilter interface as shown in the below code.

You can see in the below code I have decorated the Default1Controller with MyActionAttribute class which was created in the previous code.

Yes, we can create our own custom view engine in MVC. To create our own custom view engine we need to follow 3 steps: Step 1: In this class we should write the logic of how the view will be rendered in the render function.
