ASP.NET 3.5 –Main features:
1) AJAX integration
2) LINQ
3) Auto Properties
4) Lambda expressions

There is no direct method to access data from client side
We use these method to access..
1) Pagemethods of script manager
2) ICallbackEventHandler interface
3) XMLHttphanlder component

Enableviewstate-- property has two values "True" or "false"

We have to use ClientID property to find out the id which is dynamically generated

ASP.NET 4.0: In this framework there is an inbuilt feature for this. Following are the methods to implement them.

1) Client data controls
2) Client templates
3) Client data context

Enableviewstate --ViewStateMode property takes an enumeration that has three values: Enabled, Disabled, and Inherit.

The new ClientIDMode property is introduced to minimize the issues of earlier versions of ASP.NET.
