1. OnInit (Init) Initializes each child control of the current
2. LoadControlState: Loads the ControlState of the control. To use this method, the control must call the Page.RegisterRequiresControlState method in the OnInit method of the control.
3. LoadViewState: Loads the ViewState of the control.
4. LoadPostData: Is defined on interface IPostBackDataHandler. Controls that implement this interface use this method to retrieve the incoming form data and update the controls properties accordingly.
5. Load (OnLoad): Allows actions that are common to every request to be placed here. Note that the control is stable at this time; it has been initialized and its state has been reconstructed.
6. RaisePostDataChangedEvent: Is defined on the interface IPostBackData-Handler. Controls that implement this interface use this event to raise change events in response to the Postback data changing between the current Postback and the previous Postback. For example, if a TextBox has a TextChanged event and AutoPostback is turned off, clicking a button causes the Text-Changed event to execute in this stage before handling the click event of the button, which is raised in the next stage.
7. RaisePostbackEvent: Handles the client-side event that caused the Postback to occur
8. PreRender (OnPreRender): Allows last-minute changes to the control. This event takes place after all regular Post-back events have taken place. This event takes place before saving ViewState, so any changes made here are saved.
9. SaveControlState: Saves the current control state to ViewState. After this stage, any changes to the control state are lost. To use this method, the control must call the Page.RegisterRequiresControlState method in the OnInit method of the control.
10. SaveViewState: Saves the current data state of the control to ViewState. After this stage, any changes to the control data are lost.
11. Render: Generates the client-side HTML, Dynamic Hypertext Markup Language (DHTML), and script that are necessary to properly display this control at the browser. In this stage, any changes to the control are not persisted into ViewState.
12. Dispose: Accepts cleanup code. Releases any unman-aged resources in this stage. Unmanaged resources are resources that are not handled by the .NET common language runtime, such as file handles and database connections.
13. UnLoad

Authentication Levels
How we can set Different levels of Authentication in .Net?What are the difference between Windows Authenticatin, Passport Authentication and Form Authentication?
Read Best Answer
Editorial / Best Answer
aanand_agrawal- Member Since Apr-2009 | Apr 30th, 2009
Windows authentication enables you to identify users without creating a custom page. Credentials are stored in the Web servers local user database or an Active Directory domain. Once identified, you can use the users credentials to gain access to resources that are protected by Windows authorization.
Forms authentication enables you to identify users with a custom database, such as an ASP.NET membership database. Alternatively, you can implement your own custom database. Once authenticated, you can reference the roles the user is in to restrict access to portions of your Web site.
Passport authentication relies on a centralized service provided by Microsoft. Passport authentication identifies a user with using his or her e-mail address and a password, and a single Passport account can be used with many different Web sites. Passport authentication is primarily used for public Web sites with thousands of users.

Virtual function in c#
Explain virtual function in c# with an example

bb.geetha- Member Since May-2008 | Jun 6th, 2008
Virtual functions implement the concept of polymorphism are the same as in C#, except that you use the override keyword with the virtual function implementaion in the child class. The parent class uses the same virtual keyword. Every class that overrides the virtual method will use the override keyword.
class Shape
{
public virtual void Draw()
{
Console.WriteLine("Shape.Draw") ;
}
}
class Rectangle : Shape
{
public override void Draw()
{
Console.WriteLine("Rectangle.Draw");
}
}

Prabhat Chauhan- Member Since Jul-2008 | Jul 23rd, 2008
we know Http is an state-less protocol which is required for interaction between clinet and server .
so there is an need to remeber state of request raised by an web browser so that
web server can recognize you have already previously visited or not.
There are two types of state management techniques:
a) Client side state management
b) Server - side statemanagement
Using cookies comes under clinet side statemanagement .In HttpResponse we write
Cookie containing sessionId and other information within it.
when a browser made a request to the web server the same cookie is sent to the server where server recognize the session id and get other information stored to it previously.
Cons:
1)Cookie should contain non sensitive data as one can easily read cookies and they result of which your security may be tampered .
2) Cookie should not contain large amount of information as they are sent back and forth with request and response in between client and server which may cause your
Performance degradation
