Actions are the methods in Controller class which is responsible for returning the view or json data. This is introduced in MVC5. In this type of routing, attributes are being used to define the routes. This type of routing gives more control over classic URI Routing. This is useful in Ajax scenarios like client templates and data binding that need to post data back to the server.
Dependency Resolver again has been introduced in MVC3 and it is greatly simplified the use of dependency injection in your applications. This turn to be easier and useful for decoupling the application components and making them easier to test and more configurable.
Config in MVC4? Many bundles are added by default including jQuery libraries like - jquery. Below are the important namespaces used in MVC - System. What is Routing in ASP. In the case of a typical ASP. NET application, incoming requests are mapped to physical files such as an. The ASP. We can define routing rules for the engine, so that it can map incoming request URLs to the appropriate Controller.
But this communication is only for the server call, it becomes null if the redirect occurs. So, in short, it's a mechanism to maintain state between Controller and corresponding View.
ViewData is a dictionary object while ViewBag is a dynamic property a new C 4. On the other hand, ViewBag doesn't have typecasting and null checks. So, Tempdata can be used to maintain data between redirects, in other words from one Controller to another Controller. As previously stated about request flows in the ASP. Actually the MVC application determines the corresponding Controller using routing rules defined in Global.
And Controllers have specific methods for each user actions. Each request coming to the Controller is for a specific Action Method. As per Microsoft razor is more preferred because its light weight and has simple syntaxes. You can use windows or forms authentication for MVC.
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. 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. 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: 1. 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 Implement post-processinglogicbeforethe action happens. Cancel a current execution. Inspect the returned value. Provide extra data to the action. You can create action filters by two ways:- 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.
So we can convert the inline action filter to an action filter attribute.
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. Step We need to create a class which implements IView interface. In this class we should write the logic of how the view will be rendered in the render function. Below is a simple code snippet for the same. For instance for razor the extension is cshtml , for aspx the view extension is.
Below is how the code looks like. You can see the ViewLocationFormats is set to the Views folder and the extension is.
The best place to register the custom view engine in the ViewEngines collection is the global. Figure:-customviewengineusingMVC If you invoke this view you should see the following output.
