Has not understood the design pattern in the Aspnetforums, the massive use custom control, the N-per structure appears too complex. Beginning to think it was because of the load user def skin, today I stumbled upon an article in the Microsoft China Community, address http://www.microsoft.com/china/community/Column/93.mspx After reading, I understand some. Compare articles and Aspnetforums code to benefit a lot.
The article reads as follows:

Introduction
Remember when Microsoft just launched ASP.net, the shock is that the development of Web programs is no longer to write traditional Web pages, but like the construction of applications, so Microsoft called WebForm. But two years later today, a considerable number of developers still use the idea of writing scripts to build one after another webform, but did not play out the advantages of ASP.net, this article hope that through examples can inspire readers some new ideas.
Due to its limited space, it is not possible for this article to show the reader a webform with a design pattern through a complex web application, but if it is only a small program, there is no need to use the pattern. For the sake of understanding, it is hoped that you can imagine it as a small module in a large system (if the code is part of a large system, then the usage pattern becomes very important).

The classic WebForm architecture
First look at a simple application, database design as shown below, the portal is the subject parent table, through the Portalid for One-to-many Association, the program needs to display a different subject list according to Portalid.
According to our custom of writing WebForm, first drag a DropDownList, a DataGrid, a button control on the page:
Interface (webform.aspx):
<form id= "WebForm" method= "POST" runat= "Server" >
<asp:dropdownlist id= "DropDownList" runat= "Server" ></asp:DropDownList>
