ASP.NET 2.0 Training : Customizing the Session State Mechanism
http://www.exforsys.com/content/view/1640/354/
The stateless HTTP protocol treats each page request independently and the server is unaware of the variable values of the earlier request. The session state is a dictionary based API that is used by developers to store user specific data for the duration of the session. The session state is enabled by default for all ASP.NET applications. In ASP.NET 2.0

I initially turned to ADO.NET's DataRelation and DataSet objects so that they could handle the relationship management for me. The DataRelation object's capabilities are dead on for single tables with self-referencing keys or multi-table relationships without self-referencing keys. If your current situation falls into either of these categories, you'll want to use the DataRelation object scenario to recursively build your hierarchical structure rather than the solution described in this article. In fact, most tutorials you'll find in books or on the web deal with either of these two situations. However, I have found that the DataRelation object is a little flaky when it comes to combinations of self-referencing tables and multi-table nested relationships, particularly with those that run more than 2 levels deep or have their root level row with the same PrimaryKey as its ForeignKey ParentID. Of course, if you are using foreign key constraints, you can't just set the ParentID to 0.

ADO.NET was first introduced in version 1.0 of the .NET Framework and provided an extensive array of features to handle data either live,while connected to the database ,or when disconnected.. With the introduction of ADO.NET 2.0, you can have more features and easier programming model. Some of the newly added features include the capability to to bulk load large quantities of data from varieties of sources, to batch process updates to the database with fewer roundtrips back to the database server, to reuse the same live connection for multiple operations as well as to achieve asynchronous access to the database.

ASP.NET 2 has got several new foucs on development. Probably gridView will be your best friend of you. The GridView control automates many of the features of the DataGrid control. You have a full control on viewing, sorting, paging and editing. This sample is only a beginner guide but I hope that you will discover many features of gridView.

This tutorial uses an asp:AccessDataSource and asp:FormView to perform the count, this tutorial will demonstrate in detail how this is easily accomplished.
