It's always been easy to display data in ASP.NET by binding it to controls. But now, ASP.NET 2.0 lets you bind data that's changed or entered in the controls back to the data source as well.

ata binding is an indispensable feature of ASP.NET that links a user interface element with the underlying data store. ASP.NET 1.1 restricted this data binding to one direction only—from the business object to the web form; but ASP.NET 2.0 introduces support for binding data in both directions. This more flexible approach reduces code, simplifies data binding logic, and simplifies maintenance.
This article explores two-way data binding and illustrates how you can use the feature. The sample application that accompanies the article walks you through the process for implementing two-way data binding in ASP.NET.
