The purpose of the component is to provide the user with a consistent object oriented programming environment whether the code is stored locally or remotely. It aims to minimize software deployment and versioning conflicts and also promote safe execution of code including codes executed by trusted third parties. It is directed towards eliminating performance problems of scripted or interpreted environments. The effort is to make developer experience consistent across a variety of applications and platforms and create communication standards that help .NET framework applications integrate with all other web based applications.ASP.NET > Tips and TutorialsOct 10, 2006Exforsys
Despite all of Microsoft's best efforts to make ASP and ASP.NET coexist effortlessly, one area remains a stumbling block... session state. Fortunately the advantages of ASP.NET's upgraded session state management far outweigh the inconvenience of not being able to pass "Classic" session information to .NET. Unfortunately there is no simple solution; the most I can offer is an easy to implement workaround.
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.

DataSource controls enable programmers to declaratively connect data sources to the user interface. The logic for retrieving the data from the source is inbuilt into the control. For instance when a DropDownList is added to the form the developer is prompted to connect to the DataSource. On Clicking ?connect to DataSource?, the wizard is started to guide the user through the process of setting up the data source
