Hy, I have a validator set on the text property of a textblock. For a correct validation I would need the parent usercontrol of the textblock, but the only things I have in the validator are the value object (a string) and the culture (doesn't help either). Does anyone know a way to get certain usercontrols in a class/a method where I have no access to any kind of visual or control of my application. The problem could be solve if I could give the validator the usercontrol or the textblock as parameters, but I didn't find a way to do so.. Thank you very much for your answers. Greets
