MSDN: Data binding provides a simple way for Silverlight-based applications to display and interact with data. The way data is displayed is separated from the management of the data. A connection, or binding, between the UI and a data object allows data to flow between the two. When a binding is established and the data changes, the UI elements that are bound to the data can reflect changes automatically. Similarly, changes made by the user in a UI element can be reflected in the data object. For example, if the user edits the value in a TextBox, the underlying data value is automatically updated to reflect that change.
In XAML, data binding to an object’s property returns that property’s value. If the value is “Jerry” then you get “Jerry”.
In this article we will discuss how we can convert the value of a property to something else – something we need in our UI.
Let’s take a minute to look at simple data binding in XAML.
