Step 1: We need to add a custom global route usually in Startup. This is also a good decision if you have specific requirements for a URL scheme.
MVC is one of the most popular development frameworks for Web applications. MVC is the framework used to build Web applications for. NET and C. In this article, I list the top 50 MVC questions and their answers.
The answers are code examples written by authors of C Corner. Model—view—controller MVC is a software architectural pattern for implementing user interfaces. It divides a given software application into three interconnected parts, so as to separate internal representation of information from the way that information is presented to or accepted from the user. The View displays the data the database records. The Controller handles the input to the database records. The MVC model defines web applications with 3 logic layers, The business layer Model logic The display layer View logic The input control Controller logic The Model is the part of the application that handles the logic for the application data.
Often model objects retrieve data and store data from a database. The View is the part of the application that handles the display of the data. Most often the views are created from the model data. The Controller is the part of the application that handles user interaction.
Typically controllers read data from a view, control user input, and send input data to the model. The MVC separation helps you manage complex applications because you can focus on one aspect a time. For example, you can focus on the view without depending on the business logic. It also makes it easier to test an application.
The MVC separation also simplifies group development. Different developers can work on the view, the controller logic, and the business logic in parallel.
Learn more about ASP. What are the advantages of MVC? As a result, the scope of change is confined to the view. Full features of ASP. NET like membership providers, roles, etc can still be used. Explain MVC application life cycle? Any web application has two main execution steps, first understanding the request and depending on the type of the request sending out an appropriate response. MVC application life cycle is not different it has two main phases, first creating the request object and second sending our response to the browser.
The following is a detailed explanation of the same. So if the request is the first request the first thing is to fill the rout table with routes collection. This filling of the route table happens the global. List out different return types of a controller action method? There are total of nine return types we can use to return results from the controller to view.
The base type of all these result types is ActionResult. What are the Filters in MVC? In MVC, controllers define action methods and these action methods generally have a one-to-one relationship with UI controls such as clicking a button or a link, etc. But many times we would like to perform some action before or after a particular operation. For achieving this functionality, ASP. We will look at Action Filters in detail in this chapter.
For example, you might want to modify a view result right before the view is rendered to the browser. You can use an exception filter to handle errors raised by either your controller actions or controller action results. Action filters are one of the most commonly used filters to perform additional data processing, or manipulating the return values or canceling the execution of an action or modifying the view structure at run time.
These attributes are special. NET classes derived from System. Attribute which can be attached to classes, methods, properties, and fields. Now we will see the code example to apply these filters on an example controller ActionFilterDemoController.
ActionFilterDemoController is just used as an example. You can use these filters on any of your controllers. Explain what is routing in MVC? What are the three segments for routing important? Routing is a mechanism to process the incoming URL that is more descriptive and gives the desired response. In this case, URL is not mapped to specific files or folder as was the case of earlier days web sites.
There are two types of routing after the introduction of ASP. Routing is the URL pattern that is mapped together to a handler,routing is responsible for incoming browser request for particular MVC controller. What is Route in MVC? A route is a URL pattern that is mapped to a handler. The handler can be a physical file, such as a. A handler can also be a class that processes the request, such as a controller in an MVC application.
To define a route, you create an instance of the Route class by specifying the URL pattern, the handler, and optionally a name for the route. You add the route to the application by adding the Route object to the static Routes property of the RouteTable class.
The Routesproperty is a RouteCollection object that stores all the routes for the application. You typically do not have to write code to add routes in an MVC application. Mention what is the difference between Temp data, View, and View Bag? In ASP. ViewData ViewData is used to pass data from controller to view. It is derived from ViewDataDictionary class. It is available for the current request only.
Requires typecasting for complex data types and checks for null values to avoid an error. If redirection occurs, then its value becomes null. ViewBag ViewBag is also used to pass data from the controller to the respective view. ViewBag is a dynamic property that takes advantage of the new dynamic features in C 4. This means only from one page to another. It helps to maintain the data when we move from one controller to another controller or from one action to another action It requires typecasting for complex data types and checks for null values to avoid an error.
Most commonly, partial views are used to componentize Razor views and make them easier to build and update. Partial views can also be returned directly from controller methods.
As a result, if a URL that returns a partial view is directly invoked from the address bar of a browser, an incomplete page may be displayed. This may be something like a page that misses title, script and style sheets. Partial view is a reusable view like a user control which can be embedded inside another view. Explain what is the difference between View and Partial View?
View It contains the layout page. Before any view is rendered, viewstart page is rendered. A view might have markup tags like body, HTML, head, title, meta etc. The view is not lightweight as compare to Partial View.
Partial View It does not contain the layout page. Partial view does not verify for a viewstart. We cannot put common code for a partial view within the viewStart. Partial view is designed specially to render within the view and just because of that it does not consist any mark up. We can pass a regular view to the RenderPartial method. NET Web Form controls. Just like web form controls in ASP.
But HTML helpers are more lightweight. In most cases, an HTML helper is just a method that returns a string. ActionLink helper. With MVC, the Html. ActionLink does not link to a view. It creates a link to a controller action. The Html. ActionLink helper has several properties: Property Description. Explain attribute based routing in MVC?

In this pattern, the model represents the shape of the data and business logic. It maintains and preserves the data of the application. Model objects retrieve and store model state in a database. The view is basically and technically a user interface. The view segment displays the data-using model to the user and also enables them to modify the data.

MVC is a software architecture pattern for developing web application. It is handled by three objects Model-View-Controller. In other words applications business logic is contained within the model and is responsible for maintaining data View - It represents the user interface, with which the end users communicates. In short all the user interface logic is contained within the VIEW Controller - It is the controller that answers to user actions. Based on the user actions, the respective controller responds within the model and choose a view to render that display the user interface. The user input logic is contained with-in the controller 3 Explain in which assembly is the MVC framework is defined? The MVC framework is defined in System.
Проснувшись утром в своей постели, Беккер заканчивал день тем, что ломился в гостиничный номер незнакомого человека в Испании в поисках какого-то магического кольца. Суровый голос Стратмора вернул его к действительности. Вы должны найти это кольцо. Беккер глубоко вздохнул и перестал жаловаться на судьбу. Ему хотелось домой. Он посмотрел на дверь с номером 301. Там, за ней, его обратный билет.
Росио подошла еще ближе и изучающе смотрела на. - Хорошо, - вздохнул он, всем своим видом признавая поражение.
Беккер нахмурился. Слова Стратмора эхом звучали в его ушах. Мне нужно все, что было у Танкадо при. Все.
Милый, - глухо прошептала. - Позволь, я переберусь наверх. - Но немец даже не шевельнулся.
Поликарбонатная крыша еще была цела, но под ее прозрачной оболочкой бушевало пламя. Внутри клубились тучи черного дыма. Все трое как завороженные смотрели на это зрелище, не лишенное какой-то потусторонней величественности. Фонтейн словно окаменел. Когда же он пришел в себя, его голос был едва слышен, но исполнен решимости: - Мидж, вызовите аварийную команду.
Понятно. Она получит ваше письмо утром. - Спасибо, - улыбнулся Беккер и повернулся, собираясь уходить.
