Working MasterPage Samples
A few people have asked me for a working web site with some of the code from my MasterPage: Tips, Tricks, and Traps article. This download is a web site based on the ASP.NET Personal Web Site Starter Kit and provides a number of the samples from the article.
Samples include a master page base class, and an HttpModule to assign the MasterPageFile property for .aspx web forms at runtime. There is an example of content page to master page interaction through a strongly typed Master property, and an example of master page to content page interaction via an event.
