how to intercept WPF binding for custom processing

Question

Say you have a window with 20 textboxes on it which are all bound to different BLL classes. How do I intercept a value being passed from a textbox to a property when binding with wpf? I'm looking for a generic solution instead of doing this for every property.

I can inherit from the Binding class, but is there an event in that class I can listen to whenever data is passed from an uielement to a property? Or is there a better solution?

Answer 1

The Binding has a Converter property to which you can assign a class that implements IValueConverter. If you can inherit from binding, maybe you can set the Converter in that specialization and go on with that.
