WPF: change binding properties for multiple controls

I'd like that all the Text bindings for the TextBoxes in my UserControl to have UpdateSourceTrigger=PropertyChanged, and ValidatesOnDataErrors=True

How to do it ?

I can think of a solution: use another class for bindings (a class inheriting Binding) but maybe there is another solution, ma开发者_JAVA技巧ybe using a style or template ?

You can't do it with a style or template, since a binding is not a FrameworkElement. But your idea of a class inheriting Binding should work fine, I've done the same before for a similar problem
