Data Binding
• Simplest way to program UI controls is to write your own “glue” to
get and set properties of controls
– e.g. textBox1.Text = "Hello, world";
• In complex applications, such code quickly becomes unwieldy and
error prone.
• Use Silverlight data binding to link your UI to a class in your
application that contains your application data
– A data class that is a source for data binding is called a ViewModel
• UI controls can get their display values automatically from properties
of the viewmodel class
– Changing the property, updates the display
– User input can automatically update the bound property of the viewmodel class
