GridView Hidden Column Problem (And Two Common Solutions)
http://www.beansoftware.com/ASP.NET-Tutorials/GridView-Hidden-Column.aspx
GridView is one of the new controls in ASP.Net 2.0 that replaced the DataGrid. If you've been working in ASP.Net 2.0 since some time, you would have come to face a problem. When you design the GridView and create a bound field... In earlier versions of .Net when you didn't want the data to be visible to the client, but wanted the column for processing of data, you simply set the Column visibility to False.

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.

Visual Studio.NET is a user friendly way to create web sites. It provides for multiple ways of opening websites. Frontpage Server extensions, FTP or direct file system path can be used to open the web pages. The inbuilt web server Cassini makes IIS server optional for testing and debugging of applications. ASP.NET 2.0 uses the dynamic compilation engine to compile its files and changes to .aspx, .cs or .vb files are caught immediately.

.NET framework is a Windows Component that supports the building and running of windows applications and XML Web services. 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 2.0 solved this problem by introducing master pages. A master page is a template for other pages, with shared layout and functionality. The master page defines placeholders for content pages. The result page is a combination (merge) of the master page and the content page. More about master pages read in Master Pages in ASP.NET 2.0 tutorial
