NET Framework provides a run-time environment called the Common Language Runtime, which manages the execution of code and provides services that make the development process easier. Code that you develop with a language compiler that targets the runtime is called managed code; it benefits from features such as cross-language integration, cross-language exception handling, enhanced security, versioning and deployment support, a simplified model for component interaction, and debugging and profiling services. Memory-mapped files are used to map the content of a file to the logical address of an application. It makes you able to run multiple process on the same machine to share data with each other. To obtain a memory mapped file object, you can use the method MemoryMappedFile. It represents a persistent memory-mapped file from a file on disk. The GridView control displays the values of a data source in a table.

NET is a. NET web technology or Server side technology. To develop a web application by using. Net we have to use a. Net web technology called Asp. Net and a. Net language called C.

When we will use Not Ispostback? A IsPostBack: It is the property of the Page class which is used to determine whether the page is posted back from the client.

Whenever we dont want to execute the code within the load event, when the page load event fires then we will use! A Autopostback is the property of the control. If you want a control to postback automatically when an event is raised, you need to set the AutoPostBackproperty of the control to True.

It will provide services to single web 1. It will provide services to multiple applications. If we want to develop a web user 3. If we want to develop a custom control we have to add a pre-defined control we have to use a class library template called web user control to the project. Web user control we have to drag 4. Custom control we have to drag from from solution explorer window to web toolbox window to web page. A TextBox1. ToString ;. A By using div tag and panel control.

A Rendering is a process of converting complete server side code into client understable code. It will happen before page is submitting to the client. A ASP 1. Asp is a classic server side technology before. NET 2. Net is a. Net advanced server side technology. Net will support 2 programming techniques i. In Asp, its file extension is.

A Whenever we want to have common header and common footer within multiple pages of a website then we can go for a Master Page. A Whenever we want to display the collection of images in a rotation manner one by one then we will go for Adrotator control. A View and multiview are container controls.

Multiview control: It can contain collection of view controls but not a normal control. View Control: It can contain normal controls, but view control should be placed within the multiview.

By implementing view and multiview control we can reduce the no. A In ASP. NET we have 2 types of Configuration files. Config and 2. How many web. Config is one of the configuration files.

It is a XML file. This file we can use to define the ASP. NET application configuration settings. Config files within a single application. A YES. But the connection string names must be different. A Whenever we want to define some separate settings for couple of web pages, we will create a new folder and we will add that couple of web pages to that folder and we will add a new Web. How many machine.

A The Machine. Config file, which specifies the settings that are global to a particular machine. That is, configuration done in machine. Usually, this file is not altered.

Custom session. A Within the Web. A Using Abondon. Abondon will destroy the session. Accessing the inproc session data will be faster.

It we restart the web server or if any crashes to the web server there is a chance of losing the session data. If the session data is increased there is a burden on the web server, it will affect the performance of web server and web application. It is not suitable for large web application models like webgarden and webfarm. State server session will provide more security because sessions are creating separately within the windows service.

If we restart the web server or if any crashes to the web server but still session data will be safe. It is suitable for large web applications like webgarden and webfarm model. Accessing the state server session will be slower compare with inproc session. It is not that much suitable for small web applications because maintaining the windows service is expensive.

Application state: It will be available to all users of the application. Application state variables are cleared, when the process hosting the application is restarted. Session state: It will only be available to a specific user of the ASP. Session state variable are cleared, when the user session times out.

The default is 20 minutes. This is configurable in Web. This file will contain all the application session related events. A Cookie is a variable which we can use to store the user data. It will create within the client machine due to that reason which is called as client side state management. Cookies can be broadly classified into 2 types 1. Persistent cookies: Remain on the client computer, even after the browser is closed.

You can configure how long the cookies remain using the expires property of the Http Cookie object. Non-Persistent cookies: If you don't set the Expires property, then the cookie is called as a Non-Persistent cookie.

Non-Persistent cookies only remain in memory until the browser is closed. Cookie is a client side state management technique. Cookie is a variable which will create within the client machine. Default timeout of a cookie is 30 minutes. Session is a server side state management technique. Session is also a variable which will create within the Web server. Default life time of session variable is 20 minutes. What is the draw back?

QueryString is a way to forward the data from one web page to another. QueryString is attached to the URL with "? All the attributes and values are visible to the end user. Therefore, they are not secure. There is a limit to URL length of characters. What is the scope of view state? Viewstate will maintain the users data among multiple postbacks requests.

A ConfigurationManager class.

A Security is a process of allowing the authenticated users and denying the unauthorized users when user is requested for restricted web page. A Authorization is a process of verifying the authentication ticket and supplying the web page based on authentication ticket. A Authentication is a process of accepting the user credentials, when user will request for a restricted web page and generating the authentication ticket for the valid user.

A It will support 3 types of authentications. Forms authentication 2. Passport authentication 3. Windows authentication. A FormsAuthentication 96 When we will go for forms authentication? A Forms authentication is used for normal web applications. A A group of websites which will allow the user with single user id and password will go for the passport authentication. If we have Gmail id with that we can access Gmail, Facebook, Youtube etc. A Whenever users are part of the same Windows domain as the server then the Windows Authentication is the preferred approach to authentication.

In other words, whenever we have intranet web applications it is better to go with Windows Authentication. Row deleting and Row deleted 2. Row editing 3. Row updating and Row updated 4. Row Cancelling edit 5. Row command 6. Row created 7. Row DataBound 8. Page index changing and page index changed 9. Sorted and sorting.

It will allow the user to select one item or multiple items. It will allow the user to select only one item. ControlToValidate and 2. A It informs the compiler of any custom server control added to the page.

A To avoid full page postback,to implement partial page postback 1. A when ever user will interact the part of the page then sending postback request for only that part of the page.

A Synchronous Request Model: In this model, every client request has to communicate the web server and every request has to process by the web server then only that request, response will be getting by the client.

Asynchronous Request Model: It is a part of web browser. The role of AJAX engine is to process the part of the web page or partial web page within the client side. A AJAX will support 2 programming models. They are: Server Centric programming model: In this model every client request will be processing by the web server that can be first request or postback request.

Client Centric programming model: In this model, first request will be processing by the web server and postback request will be processing by the client. While developing an AJAX web page we can implement only server centric programming model or client centric programming model or both within single web page. And non extender controls?

Extender controls are not individual controls i. Extender controls will extend the functionalities of existing ASP. NET controls. Autocomplete extender, calendar extender, dropdown extender and so on.. Non Extender controls are individual controls i. Non Extender controls provides the extra controls in ASP. In Ajax, Script Manager is the main important parent control. Update panel is one of the Ajax Container control. By default Asp. Whenever we want to make Asp. Net controls to follow Client Centric Programming Model.

We can drag and drop update panel, in that we can add Asp. Net controls and Ajax controls. What is ADO. Why Ado. A ADO. It is an integral component in. NET framework, which was introduced by the Microsoft with. NET Framework 1. It is a Data Access Object, which allows communication between.

NET application and Databases. NET application wants to communicate Databases it has to take the help of Ado.

Net application and Database. A COA 1. NET validation controls define an important role in validating the user input data. Whenever the user gives the input, it must always be validated before sending it across to various layers of an application. If we get the user input with validation, then chances are that we are sending the wrong data. So, validation is a good idea to do whenever we are taking input from the user.

When validation is done on the client browser, then it is known as Client-Side Validation. When validation occurs on the server, then it is known as Server-Side Validation. Server-Side Validation is a secure form of validation.

The main advantage of Server-Side Validation is if the user somehow bypasses the Client-Side Validation, we can still catch the problem on server-side. There must be multiple processes to share the same connection describing the same parameters and security settings. The connection string must be identical. Cookie can store only string value. Cookies are browser dependent.

Cookies are not secure. Cookies can store only small amount of data. IL stands for Intermediate Language. NET source codes are first compiled to IL. View State is the method to preserve the Value of the Page and Controls between round trips.

It is a Page-Level State Management technique. View State is turned on by default and normally serializes the data in every control on the page regardless of whether it is actually used during a post-back. A web application is stateless. That means that a new instance of a page is created every time when we make a request to the server to get the page and after the round trip our page has been lost immediately.

These are the main features of view state: Retains the value of the Control after post-back without using a session. Stores the value of Pages and Control Properties defined in the page. Advantages of View State. Easy to Implement. No server resources are required: The View State is contained in a structure within the page load.

Enhanced security features: It can be encoded and compressed or Unicode implementation. What are the different Session state management options available in ASP.

In traditional Web programming, all information that is associated with the page, along with the controls on the page, would be lost with each roundtrip. The Microsoft ASP. NET framework includes several options to help you preserve data on both a per-page basis and an application-wide basis. These options can be broadly divided into the following two categories:.

Server-side state management enables you to manage application-related and session-related information on the server. When a class type is derived from another class type such that it inherits all the members of the base type it is Implementation Inheritance. When a type class or a struct inherits only the signatures of the functions from another type it is Interface Inheritance.
