Book Description

Dec 1 2007 Wrox Briefs (Book 12)
This Wrox Blox provides two solutions for dynamic control survivability, including using the ASP.NET Session object to hold the dynamic controls, and accessing the page's Form objects before they are destroyed. Using ASP.NET 2.0 with C# and VB.NET, you will explore both solutions and see the best situations in which to use them. Many ASP .NET programmers require the use of dynamic, page-generated controls to provide a flexible user experience. However, when creating controls on the fly within a web page, any postback to that page will destroy the original controls and the data they were holding. 

How do you retain these controls and their data when performing an otherwise destructive postback? ASP.NET programmers usually find that a web search will provide little in the way of answers to this question. This Wrox Blox provides two solutions for this common problem. The solutions proposed include using the ASP.NET Session object to hold the dynamic controls, and accessing the page’s Form objects before they are destroyed. Both of these solutions have their advantages and drawbacks. Using ASP.NET 2.0 with C# and VB.NET, you will explore both solutions and see the best situations in which to use them.

3.0 out of 5 stars A great place to start with dynamic control survibability Aug. 9 2011
By Thomas B. Knowlton - Published on Amazon.com
One caveat....the example is only for the server side controls that come with ASP.NET

The examples are NOT for use with custom user controls (.ascx) and the examples DO NOT illustrate how to sign-up for custom events that the user controls (.ascx) might raise at runtime.

The examples given are ONLY for ensuring that simple controls that are loaded at runtime do not disappear after a postback, and that their viewstate remains as it was (in other words, ensuring that selections from the dropdownlist or text entered into the textbox will not disappear). If that is your goal, then this short treatment is excellent for you.

I have yet to find any books or articles that give the topic of USER CONTROL survivability in ASP.NET decent treatment. Sigh. Such a book would explain about event wiring to controls loaded at runtime and how to preserve THAT across postbacks. It would include some discussion on Reflection, MethodInfo, EventInfo, collections of events exposed through reflection (and how to wire them up), etc.

Perhaps this will be the author's next book...

This ebook does what it says. Clearly and concisely shows you how to build dynamic controls that retain value after postback (and retrieve their values). The author actually explains 2 different methods. I bought this ebook after having no luck finding an online tutorial that I could get working in my application. Probably the most valuable 33 pages I have ever bought.
