In this example Gavin Wignall shows
6 ‘out of the box’ Silverlight Sliders and each one is linked to a different value associated with a ScrollViewer. This is all done with Data Binding inside Expression Blend with no work carried out in the C# code behind file.
Data Binding allows us ‘designers’ to hook up actions between two different objects, in this case a slider control and a scrollViewer control.
Not all elements of an object can be controlled using Data Binding, but there are plenty that can be so overall the technique is very powerful.
