Adapter Patterns and Cross Page Post Backs

Monday, July 25, 2005

It was a quiet weekend morning, and I thought I’d write up a quick blog posting with the above title. About 1400 words later, I realized I had zoomed past post length material into article length, so I put Design Considerations for Cross Page Post Backs in ASP.NET 2.0 in the main OdeToCode article area. Excerpt:

It’s also interesting to note the behavior of the PreviousPage property during a cross page post back. PreviousPage uses lazy evaluation, meaning no previous page will exist until the first time you touch the property. At that point the runtime will load a new instance of the PreviousPage web form and have it start to process the current request. This might sound odd at first, but we’ll see why the approach makes sense.
