Most-Asked ASP.NET Interview Questions with Answers
1. What is ASP.NET ?
ASP.NET belongs to Microsoft and is used for creating web applications. ASP.NET is part of the .NET Framework. ASP.NET and web forms are used to build the frontend, and the C # language is used by the backend. ASP.NET runs on the webserver IIS.
Here are some points to understand the overview of ASP.NET.
- ASP.NET provides services to enable web applications and web services creation, deployment, and implementation.
- ASP.NET A is server-side technology like ASP.
- Web applications are created in web forms. ASP.NET comes with an integrated web form control responsible for generating a user interface.
- These reflect common HTML widgets such as text boxes and buttons. If these controls do not meet your needs, you can create your user controls.
- WebForms is designed to make building web-based applications as easy as building Visual Basic applications.
2. Tell me about the top 5 advantages of ASP.NET ?
HTML Separation of Code
You can also completely disconnect the layout and business logic to create a clean sweep in ASP.NET. This makes it much easier for us to work efficiently as programmers and designers. If table games are your thing, we recommend the https://www.siliconvalleycloudit.com/tortoise-rock-casino-twentynine-palms-ca/ desktop instant play client.
Support for ordered languages
Engineers can utilize VB.NET and get the right of passage to capacities including strong composing and item orientated programming. Utilizing ordered languages furthermore approach that ASP.NET pages in all actuality do now presently not go through the general execution results connected with deciphered code. ASP.NET pages are precompiled to byte-code and Just In Time (JIT) accumulated while first mentioned. Resulting demands are coordinated to the totally ordered code that is stored till the stock changes.
Utilize the administrations gave by the .NET Framework
The .NET Framework gives a class library that your application can utilize. A few significant classes are valuable for I/O, admittance to working framework administrations, information access, and in any event, investigating.
Realistic improvement climate
Visual Studio .NET gives web engineers an extremely rich advancement climate. Likewise with Visual Basic 6, you can relocate controls to set properties. It additionally completely upholds IntelliSense for HTML and XML as well as code.mpiling on a byte code and is aggregately arranged when made interestingly. Ensuing solicitations are shipped off the completely gathered code and stored until the source changes.
To resolve the issues referenced above, ASP.NET gives an answer for meeting and application state the executives. Status data can, for instance, be put away in the information base or the data set. It very well may be divided among web ranches and the state data can be reestablished regardless of whether the server goes down or the association is lost.
3. Tell me about the 2 different validators in ASP.NET ?
ASP.NET validation controls have a significant part in validating user input. Whenever a user provides input, it should be validated before sending it to different layers of the application. If you receive user input with validation, you may be sending incorrect data.
Therefore, we recommend that you always validate when you receive input from users.
- Client-side Validation is when the validation is performed by the client browser, this is called client-side validation.
- Server-Side Validation Performing validation on the server is called server-side validation. Server Side Validation is a secure form of validation, so the main benefit of server-side validation is that it can detect problems on the server-side, even if the user bypasses the client-side validation in any way.
4. What is client-side state management in ASP.NET ?
ASP.NET provides several ways to store state information on the client. These include:
ASP.NET uses view state to keep track of control values between page requests. It only works within the page. View state values are not available on the following pages.
You can store information about a control that is not part of the view state. When the view state is disabled for control or page, the state of the control continues to function.
Stores data without displaying its controls and data in the user’s browser. This data is returned to the server and is available when the form is processed. Hidden field data is only available within the page (page area data).
Cookies are small pieces of information that the server creates in your browser. Cookies store values in your browser that the browser sends with each page request to the webserver.
The query string stores the value at the end of the URL. This value is displayed to the user through the browser’s address bar. Query strings are not protected. Do not send secrets via query string.
5. What do you know about the Server-side management system?
The following objects are used to store information on the server:
This object stores data that can be used by all pages in this web application. The Application object contains global variables for ASP.NET applications.
Caching is the process of storing frequently used data by users. Caching improves the performance, scalability, and availability of applications. Data can be intercepted by either the server or the client.
Session objects store user data between individual requests. This object is similar to the Application object, but stores data about a specific user.
6. What are the Cookies?
A cookie is a small amount of data that the server generates on the client. When a web server creates a cookie, an additional HTTP header is sent to the browser when the page is served to the browser. The HTTP headers are:
- Set-Cookie: message=Hi.
After the cookie is created by the browser, whenever the browser requests a page from the same application in the future, the browser sends a header like this:
- Cookie: Message=Hi
Cookies are tiny segments of data in textual form. When using cookies, only string values can be stored. There are two types of cookies.
Session cookies only exist in memory, which are permanently deleted when the user closes the web browser.
Persistent cookies, on the other hand, can be used for months or years. When you create a persistent cookie, the cookie is permanently stored by your browser on your computer.
7. Tell me about Session Object in ASP.NET ?
HTTP is a stateless protocol. The web page cannot store user information. If the user pastes some information and moves to the next page, this data is lost and the user cannot retrieve the information.
To access this information, you must save it. Sessions provide the ability to store information in the server’s memory. It can support all kinds of objects to save. Session data is stored individually for each user. That is, the session is user-specific.
8. Describe the Pros and Cons of Session Object?
Here are the main pros and cons of using sessions in ASP. The time span is usually between one and four https://www.fontdload.com/a-que-edad-entras-al-casino-de-baltimore/ weeks. NET:
- It stores user states and data that can be used throughout the application.
- It’s an easy-to-implement mechanism and can store any object. Be sure to fully understand the deal on offer before moving forward https://www.fontdload.com/the-pearl-palms-casino-resort-las-vegas/ so the right steps are taken to access the promotion.
- We store each user’s data separately.
- Because the session object is stored on the server, the session is secure and transparent to the user.
- Performance overhead for large numbers of users because session data is stored in server memory.
- The overhead associated with serializing and deserializing session data. This is because the
- StateServer and SQLServer session modes require the object to be serialized before saving
9. Tell me in detail about the View State?
View state is a way to maintain values on the page and control between round trips, How to manage page-level state. View state is enabled by default and typically serializes data in all controls on the page, whether or not they are used during a postback.
Web applications are stateless. This means that whenever you send a page fetch request to the server, a new page instance is created and the page is lost immediately after a round trip.
View state Characteristics
These are the main characteristics of view states.
- Preserves the control’s value after postback without using a session
- Stores page values and control properties defined on the page.
- Create a custom view state provider that you can use to store view state information in a SQL Server database or other data stores.
View state benefits
- Easy to implement
- No server resources required
- The view state is contained in the structure within the page loading process
Advanced security features:
- Encoding and compression or Unicode implementation are possible.
10. Explain AJAX in detail ?
Instead of posting the entire page back, the page is partially rendered on the server. Use AJAX to build faster, better, and more interactive web applications. The cookie is used to store the user consent for the cookies in the https://teyasilk.com/what-time-ddes-hugo-at-rivets-casino-open-todau/ category “Performance”. AJAX uses HTTP requests between your web server and your browser.
11. What is garbage collection in ASP.NET?
This is the system where the run-time component is responsible for managing the lifetime of the object and the heap memory it occupies.
12. Describe Caching in details?
Caching is a technique for storing frequently used items in memory for faster access. Recommendations of hundreds of online pokies slots , blackjack, https://starlitenewsng.com/no-me-deja-jugar-en-el-casino-gta-v/ roulette, and video poker games. By caching the response, the request is processed by the response already stored in memory. Caching introduces overhead, so it is important to carefully choose the items you want to cache.
Web forms that do not contain frequently used and frequently changed data are good candidates for caching. The cached web form freezes the server-side content of the form, and changes to that content are not reflected until the cache is refreshed.
13. Tell me about the Assembly in ASP.NET?
The assembly exists as .dll or .exe containing the MSIL code executed by the CLR. Assemblies contain interfaces and classes, and can also contain other resources such as bitmaps and files. It contains details of the version used by the CLR during execution.
You can run two assemblies with the same name but different versions side by side, so you can use that version of the assembly in an application that depends on a particular version.
An assembly is a unit to which permissions are granted. It can be private or global. Private assemblies are only used by the application to which they belong, while global assemblies can be used by any application on the system.
14. Tell about different Data Controls in ASP.NET?
Controls that have a DataSource property are called data controls in ASP.NET. ASP.NET enables powerful data binding features and allows you to bind any server control to simple properties, collections, expressions, and/or methods. Data binding gives you more flexibility when working with data such as databases. Data binding controls are container controls.
Control> Child Control Data Binding binds a control to database data. Data binding allows you to bind controls from the database to specific columns in a table, or to bind an entire table to a data grid. Data binding provides a simple, convenient and powerful way to create read / write connections between form controls and application data.
Data binding allows you to integrate the results of properties, collections, method calls, and database queries into your ASP.NET code. You can combine data binding with web control rendering to reduce much of the programming effort involved in creating web controls. You can also use data binding with ADO.NET and web controls to set control content from SQLselect statements or stored procedures.
15. What do you know about the Login Controls in ASP.NET?
Login controls provide a user interface for users to log in to a website. The login control uses the membership service to authenticate the user with the membership system. The default membership service in the configuration file is automatically used, but you can also specify the membership provider to use as a property of the control.
16. What is Repeater Control?
Repeaters are data-bound controls. Data binding controls are container controls. Create a link between the data source and the presentation UI to display the data. Repeater controls are used to display a repeating list of items.
The main use of repeater controls is to display a repeating list of items bound to the control. Repeater controls are faster and lighter for displaying data than GridView or DataGrid. Repeater controls allow you to view your data in a custom format. The main drawback of repeater controllers is that they do not support paging and sorting.
