Source: MSDN Accessing and Updating Data in ASP.NET 2.0: Data Source Control Basics 11 Jan 2006 00:00 GMT
When I started my career as a web developer, Microsoft's Active Server Pages version 2.0 had just burst onto the scenes.
Back in my day, web developers were responsible for writing code to both access and display data. That is, we had to write
code that queried the database and then had to write more code to squirt out the appropriate data surrounded by the
applicable HTML elements. ASP.NET version 1.x simplified this process
with the host of data Web controls (the DataGrid, DataList, Repeater, DropDownList, and so on). With just two lines of code
these controls could emit their own, proper HTML elements when given an arbitrary data source. Today, with
ASP.NET version 2.0 and its data source controls, developers can both
access data and display it without writing a lick of code. You kids have it so easy these days!
In a nutshell, the ASP.NET 2.0 data source controls provide a declarative way to work with data. Rather than having to
write code to connect to a database, issue a command, and retrieve the results as a DataReader or DataSet, with the
data source controls these instructions can be specified through the standard Web control syntax. (Of course behind the scenes, the
data source controls are still performing the programmatic steps we had to take in ASP.NET 1.x.) Once a data source control
has been properly configured, it can be bound to any data Web control. When the page is visited, the data Web control
will automatically invoke the associated data source control, retrieve its data, and display it as configured.
While the data source controls are easy to get started with, there are a number of subtleties and issues that can cause
headaches. In this article series we'll examine the five built-in data source controls in detail. This first part, however,
examines the concepts shared among all five data source controls and how ASP.NET 2.0's data Web controls work with their
associated data source controls at runtime. Read on to learn more!
