• ASP.NET MVC is a design pattern that separates the UI and logic, providing better maintainability and testability.

• MVC allows for more control over the HTML, CSS, and JavaScript, making it easier to cre...read more

Partial is a method in MVC that renders a specific portion of a view, while render partial renders a partial view.

• Partial is used to render a specific portion of a view, while render partial is used to render a partial view.

• Partial is typically used within a view to render a reusable component, while render partial is used to render a separate partial view.

Different ways to send data view to controller

• Using form submission

• Using AJAX requests

• Using URL parameters

• Using cookies or local storage

• Using web sockets

jQuery post is a shorthand method for Ajax post in MVC.

• jQuery post is a shorthand method for Ajax post in MVC

• jQuery post uses the $.post() method while Ajax post uses $.ajax() method

• jQuery post is simpler and easier to use than Ajax post

• Both methods are used to send data to the server without reloading the page

Ajax is a technique used to send and receive data from a server without refreshing the entire web page.

• Ajax stands for Asynchronous JavaScript and XML.

• It allows for asynchronous communication between the client and server.

• With Ajax, form submission can be done without reloading the entire page.

• The data is sent to the server in the background and the response can be processed without interrupting the user's interaction ...read more

Different types of action result in MVC include ViewResult, PartialViewResult, JsonResult, and RedirectResult.

• ViewResult: Returns a complete HTML view to the client.

• PartialViewResult: Returns a partial HTML view to the client.

• JsonResult: Returns JSON data to the client.

• RedirectResult: Redirects the client to a different URL.

Routing in MVC is the process of mapping URLs to specific actions or controllers in an application.

• Routing determines how an incoming request is handled and which controller and action should be executed.

• It helps in creating clean and user-friendly URLs.

• Routes can be defined using attributes or in a route configuration file.

• Parameters can be passed in the URL and accessed in the controller action.

• Routing can also handl

Security in MVC involves implementing authentication, authorization, and secure communication to protect web and API resources.

• Implement authentication mechanisms like username/password, tokens, or OAuth.

• Use authorization to control access to resources based on user roles and permissions.

• Secure communication by using HTTPS and encrypting sensitive data.

• Implement input validation and sanitization to prevent common secur...read more

Validation technique in MVC is used to ensure that the data entered by the user is valid and meets the specified criteria.

• Validation can be performed at different levels in MVC, such as client-side validation using JavaScript or server-side validation using data annotations or custom validation logic.

• Client-side validation provides immediate feedback to the user without making a round trip to the server, while server-s...read more

Dependency injection is a design pattern where the dependencies of a class are provided externally rather than created internally.

• Dependency injection helps in achieving loose coupling and improves testability and maintainability.

• There are three types of dependency injection: constructor injection, setter injection, and interface injection.

• In constructor injection, dependencies are provided through the class constructo...read more

MVC filters are used in projects to handle cross-cutting concerns and provide a way to intercept and modify the behavior of MVC actions.

• MVC filters are attributes that can be applied to controllers or actions.

• They can be used to perform tasks like authentication, authorization, logging, exception handling, etc.

• Filters can be applied globally, at the controller level, or at the action level.

• There are different types of ...read more

Singleton design pattern restricts the instantiation of a class to one object.

• Used when only one instance of a class is required throughout the project

• Provides a global point of access to the instance

• Can be implemented using a private constructor and a static method

• Examples include database connections, configuration settings, and logger classes

Abstract classes are classes that cannot be instantiated and can have both abstract and non-abstract methods. Interfaces are contracts that define the methods that a class must implement.

• Abstract classes can have constructors while interfaces cannot

• A class can implement multiple interfaces but can only inherit from one abstract class

• Abstract classes can have instance variables while interfaces cannot

• Interfaces can have...read more

A cursor is used to retrieve and manipulate data from a database, while a while loop is a control structure used to repeat a block of code.

• Cursors are used in database operations, while while loops are used in programming logic.

• Cursors are typically used to iterate over a result set, while while loops can be used for any repetitive task.

• Cursors can be more efficient for large result sets, while while loops are generall...read more

Stored procedures and functions are both database objects used to encapsulate a set of SQL statements, but they have some differences.

• Stored procedures are used to perform an action or a series of actions, while functions are used to return a value.

• Stored procedures can have input and output parameters, while functions can only have input parameters.

• Stored procedures can modify data, while functions are read-only.

• Store...read more
