Simplify Data Binding In ASP.NET 2.0 With Our Custom Control

摘要

ASP.NET 2.0 includes many new data binding features that can significantly simplify a variety of data binding scenarios. Unfortunately, one very common scenario—simple control data binding—has changed very little. While this is a common scenario in forms-based Web applications, it remains for the most part a manual and time-consuming process. Simple control data binding refers to the process of binding a single value to a property of a control—for instance, binding form controls like textboxes, checkboxes, radio buttons, or selected values of list controls to individual data or object values. This could benefit significantly from a consistent approach to handling data binding deterministically, as well as managing error trapping and display consistently. In this article, I introduce a custom extender control that can be used to bind any individual value from data or objects to any control property. It can extend and provide designer support for any existing control on a Web Form.
