Hey,
The data binding stuff is still a little fresh, though already very powerful. I'm working on a tutorial that will go through some of the basics of data binding and should have that done in a few days.
The Eto.Test application does do some data binding, which you can search for ".Bind" and you'll pretty much see all the examples.
Binding can be done to a DataContext, a specific object instance, or directly get/set values. You can bind using reflection with the PropertyBinding, using delegates using DelegateBinding, or to an object in an IList/Array using a ColumnBinding.
I'll let you know when the tutorial has been pushed to github, and I'll start working on a wiki entry for it as well to go into more detail.
Cheers!
Curtis.
