I've been trying to get something like this for ages, but AFAIK it isn't possible. Unless they make "Properties" bindable and then you make a new binding source that points to ... arg, my head hurts already.
It would be sweet. I'm sure there is a way to do it with custom code, like creating a custom Binding derived class which knows about the properties class and, then binding to "ReadOnly" property.
Hm... maybe I'll try something like that.
