Asp.Net Interview Question and Answer
1.What is ASP?
2. What is ASP.NET?
Ans - ASP.NET is a specification developed by Microsoft to create dynamic Web applications, Web sites, and Web services. It is a part of .NET Framework. You can create ASP.NET applications in most of the .NET compatible languages, such as Visual Basic, C#, and J#. The ASP.NET compiles the Web pages and provides much better performance than scripting languages, such as VBScript. The Web Forms support to create powerful forms-based Web pages. You can use ASP.NET Web server controls to create interactive Web applications. With the help of Web server controls, you can easily create a Web application.
3. What is the basic difference between ASP and ASP.NET?
Ans - The basic difference between ASP and ASP.NET is that ASP is interpreted; whereas, ASP.NET is compiled. This implies that since ASP uses VB Script; therefore, when an ASP page is executed, it is interpreted. On the other hand, ASP.NET uses .NET languages, such as C# and VB.NET, which are compiled to Microsoft Intermediate Language (MSIL).
4. In which event are the controls fully loaded?
Ans - Page load event guarantees that all controls are fully loaded. Controls are also accessed in Page_Init events but you will see that view state is not fully loaded during this event
5. How can we identify that the Page is Post Back?
Page object has an "Is Post Back" property, which can be checked to know that is the page posted back.
6. What is the lifespan for items stored in View State?
The items stored in View State live until the lifetime of the current page expires including the post backs to the same page.
7. How information about the user's locale can be accessed?
The information regarding a user's locale can be accessed by using the System. Web .UI. Page. Culture property.
8. What is the difference between SQL notification and SQL invalidation?
The SQL cache notification generates notifications when the data of a database changes, on which your cache item depends. The SQL cache invalidation makes a cached item invalid when the data stored in a SQL server database changes.
9. Which is the parent class of the Web server control?
The System. Web .Ul. Control class is the parent class for all Web server controls.
10. Can you set which type of comparison you want to perform by the Compare validate control?
Yes, by setting the Operator property of the Compare validate control.
11. What is the behavior of a Web browser when it receives an invalid element?
The behavior of a Web browser when it receives an invalid element depends on the browser that you use to browse your application. Most of the browsers ignore the invalid element; whereas, some of them display the invalid elements on the page.
12. What are the advantages of the code-behind feature?
The code-behind feature of ASP.NET offers a number of advantages:
Makes code easy to understand and debug by separating application logic from HTML tags
Provides the isolation of effort between graphic designers and software engineers
Removes the problems of browser incompatibility by providing code files to exist on the Web server and supporting Web pages to be compiled on demand.
13. How do you sign out from forms authentication?
The Forms Authentication. Signout ( ) method is used to sign out from the forms authentication.
14. What is Auto Post Back?
If you want a control to post back automatically when an event is raised, you need to set the Auto Post Back property of the control to True
15. What is the function of the View State property?
The ASP.NET 4.0 introduced a new property called View State Mode for the Control class. Now you can enable the view state to an individual control even if the view state for an ASP.NET page is disabled.
16. Why do you use the App_Code folder in ASP.NET?
The App_Code folder is automatically present in the project. It stores the files, such as classes, typed data set, text files, and reports. If this folder is not available in the application, you can add this folder. One of the important features of the App_Code folder is that only one dll is created for the complete folder, irrespective of how many files it contain.
17. Define a multilingual Web site.
A multilingual Web site serves content in a number of languages. It contains multiple copies for its content and other resources, such as date and time, in different languages.
18. What is an ASP.NET Web Form?
ASP.NET Web forms are designed to use controls and features that are almost as powerful as the ones used with Windows forms, and so they are called as Web forms. The Web form uses a server-side object model that allows you to create functional controls, which are executed on the server and are rendered as HTML on the client. The attribute, run-at "server", associated with a server control indicates that the Web form must be processed on the server.
19. What is the difference between a default skin and a named skin?
The default skin is applied to all the Web server controls in a Web form, which are of similar type, and it does not provide a Skin ID attribute. The named skin provides a Skin ID attribute and users have to set the Skin ID property to apply it.
20. What is IIS? Why is it used?
Internet Information Services (IIS) is created by Microsoft to provide Internet-based services to ASP.NET Web applications. It makes your computer to work as a Web server and provides the functionality to develop and deploy Web applications on the server. IIS handles the request and response cycle on the Web server. It also offers the services of SMTP and FrontPage server extensions. The SMTP is used to send emails and use FrontPage server extensions to get the dynamic features of IIS, such as form handler.
21. What is Query String? What are its advantages and limitations?
The Query String helps in sending the page information to the server.
The Query String has the following advantage
Every browser works with Query Strings
It does not require server resources and so does not exert any kind of burden on the server.
The following are the limitations of Query String:
Information must be within the limit because URL does not support many characters.
Information is clearly visible to the user, which leads to security threats.
22. What is actually returned from server to the browser when a browser requests an .aspx file and the file is displayed?
When a browser requests an .aspx file then the server returns a response, which is rendered into a HTML string.
23. How can you display all validation messages in one control?
The Validation Summary control displays all validation messages in one control.
24. Which two new properties are added in ASP.NET 4.0 Page class?
The two new properties added in the Page class are Meta Keyword and Meta Description.
25. What is tracing? Where is it used?
Tracing displays the details about how the code was executed. It refers to collecting information about the application while it is running. Tracing information can help you to troubleshoot an application. It enables you to record information in various log files about the errors that might occur at run time. You can analyze these log files to find the cause of the errors.
In .NET, we have objects called Trace Listeners. A listener is an object that gets the trace output and stores it to different places, such as a window, a file on your locale drive, or a SQL Server.
The System.Diagnostics namespace contains the predefined interfaces, classes, and structures that are used for tracing. It supplies two classes, Trace and Debug, which allow you to write errors and logs related to the application execution. Trace listeners are objects that collect the output of tracing processes.
26. What is the difference between authentication and authorization?
Authentication verifies the identity of a user and authorization is a process where you can check whether or not the identity has access rights to the system. In other words, you can say that authentication is a procedure of getting some credentials from the users and verify the user's identity against those credentials. Authorization is a procedure of granting access of particular resources to an authenticated user. You should note that authentication always takes place before authorization.
27. How can you register a custom server control to a Web page?
You can register a custom server control to a Web page using the @Register directive.
28. Which ASP.NET objects encapsulate the state of the client and the browser?
The Session object encapsulates the state of the client and browser.
29. Differentiate globalization and localization.
The globalization is a technique to identify the specific part of a Web application that is different for different languages and make separate that portion from the core of the Web application. The localization is a procedure of configuring a Web application to be supported for a specific language or locale.
30. What is View State?
The View State is a feature used by ASP.NET Web page to store the value of a page and its controls just before posting the page. Once the page is posted, the first task by the page processing is to restore the View State to get the values of the controls.
31. Which method is used to force all the validation controls to run?
The Page.Validate() method is used to force all the validation controls to run and to perform validation.
32. Which method has been introduced in ASP.NET 4.0 to redirect a page permanently?

33. How can you send an email message from an ASP.NET Web page?
You can use the System. Net.Mail. Mail Message and the System. Net .Mail. SMPTS Mail classes to send an email in your Web pages. In order to send an email through your mail server, you need to create an object of the Smtp Client class and set the server name, port, and credentials.
34. What is the difference between the Response.Write() and Response.Output.Write() methods?
The Response.Write() method allows you to write the normal output; whereas, the Response.Output.Write() method allows you to write the formatted output.
35. What does the Orientation property do in a Menu control?
Orientation property of the Menu control sets the horizontal or vertical display of a menu on a Web page. By default, the orientation is vertical.

37. How does a content page differ from a master page?
A content page does not have complete HTML source code; whereas a master page has complete HTML source code inside its source file.
38. Suppose you want an ASP.NET function (client side) executed on the Mouse Over event of a button. Where do you add an event handler?
The event handler is added to the Add() method of the Attributes property.
39. What is the default timeout for a Cookie?
The default time duration for a Cookie is 30 minutes.
40. What are HTTP handlers in ASP.NET?
HTTP handlers, as the name suggests, are used to handle user requests for Web application resources. They are the backbone of the request-response model of Web applications. There is a specific event handler to handle the request for each user request type and send back the corresponding response object.
Each user requests to the IIS Web server flows through the HTTP pipeline, which refers to a series of components (HTTP modules and HTTP handlers) to process the request. HTTP modules act as filters to process the request as it passes through the HTTP pipeline. The request, after passing through the HTTP modules, is assigned to an HTTP handler that determines the response of the server to the user request. The response then passes through the HTTP modules once again and is then sent back to the user.
You can define HTTP handlers in the <http Handlers> element of a configuration file. The <add> element tag is used to add new handlers and the <remove> element tag is used to remove existing handlers. To create an HTTP handler, you need to define a class that implements the Http Handler interface.
41. What are the events that happen when a client requests an ASP.NET page from IIS server?
The following events happen when a client requests an ASP.NET page from the IIS server:
User requests for an application resource.
The integrated request-processing pipeline receives the first user request.
Response objects are created for each user request.
An object of the Http Application class is created and allocated to the Request object.
The Http Application class processes the user request.
42. Explain file-based dependency and key-based dependency.
In file-based dependency, you have to depend on a file that is saved in a disk. In key-based dependency, you have to depend on another cached item.
43. How can you implement the post back property of an ASP.NET control?
You need to set the Auto Post Back property to True to implement the Post Back property of controls.
44. Explain how Cookies work. Give an example of Cookie abuse.
The server tells the browser to put some files in a cookie, and the client then sends all the cookies for the domain in each request. An example of cookie abuse is large cookies affecting the network traffic.
45. Explain lo gin controls.
Login controls are built-in controls in ASP.Net for providing a login solution to ASP.NET application. The login controls use the membership system to authenticate a user credentials for a Web site.
There are many controls in login controls
Change Password control - Allows users to change their password.
Create User Wizard control - Provides an interface to the user to register for that Web site.
Login control - Provides an interface for user authentication. It consists of a set of controls, such as Text Box, Label, Button, Check Box, Hyper Link
Login View control - Displays appropriate information to different users according to the user's status.
Login Status control - Shows a login link to users, who are not authenticated and logout link, who are authenticated
Login Name control - Displays a user name, if the user logs in.
Password Recovery control - Allows users to get back the password through an e-mail, if they forget.
46. What is the use of Place Holder control? Can we see it at run time?
The Place Holder control acts as a container for those controls that are dynamically generated at runtime. We cannot see it at run time because it does not produce any visible output. It used only as a container.
47. What setting must be added in the configuration file to deny a particular user from accessing the secured resources?
To deny a particular user form accessing the secured resources, the web.config file must contain the following code:
<deny users="username" />
48. What are the event handlers that can be included in the Global. asax file?
The Global .asax file contains some of the following important event handlers:
49. What is the difference between page-level caching and fragment caching?
In the page-level caching, an entire Web page is cached; whereas, in the fragment caching, a part of the Web page, such as a user control added to the Web page, is cached.
50. Make a list of all templates of the Repeater control.
The Repeater control contains the following templates:
51. Describe the complete life cycle of a Web page.
When we execute a Web page, it passes from the following stages, which are collectively known as Web page life cycle:
Page request - During this stage, ASP.NET makes sure the page either parsed or compiled and a cached version of the page can be sent in response
Start - During this stage sets the Request and Response page properties and the page check the page request is either a post back or a new request
Page Initialization - During this stage, the page initialize and the control's Unique Id property are set
Load - During this stage, if the request is post back, the control properties are loaded without loading the view state and control state otherwise loads the view stat
Validation - During this stage, the controls are validated
Post back event handling - During this stage, if the request is a pos tback, handles the event
Rendering - During this stage, the page invokes the Render method to each control for return the output
Unload - During this stage, when the page is completely rendered and sent to the client, the page is unloaded.
