Rather, let me give Joel Spolsky's advice from his great essay, The Law of Leaky Abstractions: "Learn how to do it manually first, then use [data source controls] to save time.

Code generation tools which pretend to abstract out something, like all abstractions, leak, and the only way to deal with the leaks competently is to learn about how the abstractions work and what they are abstracting.

Data source controls provide for a page developer to access and modify data without needing to write a lick of code, thereby greatly reducing the code repetition seen in ASP. The Sql Data Source control, for example, is used to access data from a relational database, whereas the Xml Data Source can work with data from an XML file.

Regardless of the data source control being used, they are plugged into the data Web controls in the same manner.

When emitting data to a web page with classic ASP, page developers needed to write code to iterate through the database results and display not only the contents of the current record, but also the HTML that accompanied the record.

For example, to display the results of a database query in an HTML ).

However, anytime a new layer of abstraction is added on top of another, it permits developers to forgo education on the lower layers of abstraction.

And this works well until something goes awry, and one layer of abstraction "leaks" into another.

In addition to reducing the sheer volume of code needed, the data Web controls also remove the domain expertise needed with simpler technologies like classic ASP.

For example, with classic ASP the page developer needed to know the precise syntax and semantics of the HTML element. NET developer using a Data Grid, however, really doesn't need to know squat about the HTML syntax for displaying a table (although such knowledge is definitely helpful).

NET 1.x.) Once a data source control has been properly configured, it can be bound to any data Web control.
