Day 16. ADO.NET in the Presentation Services Tier

for RuBoard

As you learned yesterday , how you design your data services tier has an effect on how the presentation services tier will work with the data in your application. Today, you'll explore those differences in the context of both Windows Forms and Web Forms user interfaces.

Today's discussion will concentrate on how to display and work with data exposed by the objects associated with a DataSet and data reader because the majority of user interfaces will use these classes directly. However, we'll also discuss the architecture of data binding, for example, so that you understand how classes you build can also take advantage of the features of controls.

Today, you'll learn the following concepts:

How to use both simple and complex binding in Windows Forms applications
How to validate data in Windows Forms applications
How to use both single-value and multi-record binding in Web Forms applications
How to store state in Web Forms applications
How to validate data in Web Forms applications
