Amdocs Most Frequently Asked ASP.NET MVC Interview Questions Answers
Do You Know About The New Features In Asp.net Mvc 5?
Following are features added newly : Mobile templates Added ASP.NET Web API template for creating REST based services. Asynchronous controller task support. Bundling of the java scripts. Segregating the configs for ASP.Net MVC routing, Web API, Bundle etc.
What Is The Use Of View Model In Asp.net Mvc?
View Model is a plain class with properties, which is used to bind it to strongly typed view. View Model can have the validation rules defined for its properties using data annotations.
What You Mean By Routing In Asp.net Mvc?
Routing is a pattern matching mechanism of incoming requests to the URL patterns which are registered in route table. Class : "UrlRoutingModule" is used for the same process.
What Are Actions In Asp.net Mvc?
Actions are the methods in Controller class which is responsible for returning the view or json data. Action will mainly have return type : "ActionResult" and it will be invoked from method : "InvokeAction()" called by controller.
What Is Attribute Routing In Asp.net Mvc?
ASP.NET Web API supports this type routing. This is introduced in ASP.Net 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.
Attribute Routing can be defined at controller level or at Action level like
[Route("{action = TestCategoryList}")] - Controller Level
[Route("customers/{TestCategoryId:int:min(10)}")] - Action Level
How To Enable Attribute Routing?
Just add @Model.CustomerName the method : "MapASP.Net MVCAttributeRoutes()" to enable attribute routing as shown below
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
//enabling attribute routing
routes.MapASP.Net MVCAttributeRoutes();
//convention-based routing
routes.MapRoute
(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Customer", action = "GetCustomerList", id = UrlParameter.Optional }
);
}
What Are The Options Can Be Configured In Ajax Helpers?
Below are the options in AJAX helpers
Url : This is the request URL.
Confirm : This is used to specify the message which is to be displayed in confirm box.
OnBegin : Javascript method name to be given here and this will be called before the AJAX request.
OnComplete : Javascript method name to be given here and this will be called at the end of AJAX request.
OnSuccess - Javascript method name to be given here and this will be called when AJAX request is successful.
OnFailure - Javascript method name to be given here and this will be called when AJAX request is failed.
UpdateTargetId : Target element which is populated from the action returning HTML.
What Is Layout In Asp.net Mvc?
Layout pages are similar to master pages in traditional web forms. This is used to set the common look across multiple pages. In each child page we can find : /p>
@{
Layout = "~/Views/Shared/TestLayout1.cshtml";
} This indicates child page uses TestLayout page as it's master page.
Explain Json Binding?
JavaScript Object Notation (JSON) binding support started from ASP.Net MVC3 onwards via the new JsonValueProviderFactory, which allows the action methods to accept and model-bind data in JSON format. This is useful in Ajax scenarios like client templates and data binding that need to post data back to the server.
Explain Dependency Resolution?
Dependency Resolver again has been introduced in ASP.Net 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.
Explain Bundle.config In Asp.net Mvc5?
"BundleConfig.cs" in ASP.Net MVC5 is used to register the bundles by the bundling and minification system. Many bundles are added by default including jQuery libraries like - jquery.validate, Modernizr, and default CSS references.
