Your users may want to get their data in a specific order -- and not get it all at once. You can control both with the ObjectDataSource (and a little code).
Not content with providing a solution for displaying information from the Content page on its MasterPage, Peter returns to the topic to solve the problem from another direction.
Validator controls make handling errors and reporting them in the UI easy, but what you may not know is how easy it is to create your own Validator.
In his ongoing campaign to convince ASP.NET developers that User Controls are a simple way to start implementing customizable pages, Peter shows how to improve the integration between User Controls and ASP.NET's WebPart framework.
If you're concerned about keeping critical information in your Web.config file, then you should encrypt it -- or at least the parts that you're concerned about.
If you want to use Entity Framework in ASP.NET, you're going to need to handle concurrency problems. Here are some suggestions from a Microsoft "architect evangelist."
Peter revisits the problem of dealing with multiple updates to the same data, but this time he looks at a solution that involves the ObjectDataSource.

Set aside ASP.NET for now. Let's talk about the most fundamental error developers make in designing their site's user interface.
To fully exploit User Controls, you need to treat them as object -- which includes having them fire events. If firing your own events is new to you, here's a step-by-step guide.
