Silverlight Bind Data using DataTempale in VB.NET
In this article you will learn how to Bind Data using DataTempale in Silverlight.
DataBinding: Databinding is the magic that that sits between your objects (know as a model) and the UI (known as a view). The model isn't concerned with how the data will appear in front of the user â€" it's job is to hold the data. Silverlight data binding features are flexible and powerful, and provide you with everything you need to build an effective business application.
