Register all textboxes to the same event

Question

i all,

I have a lot (about 30) TextBoxes in the same window and I want to register all of them to the same PreviewKeyDown Event. Is there any easy way of signing all of them without the need to sign each of the textBoxes (in the XAML code) individualy?

Thanks in advance,

Gil.

Well thanks, but were do I put this code? I'm receiving this (static) error: "RegisterClassHandler is a Method but used like a type"

Yes, you can do it from the VS designer which will then write the XAML for you. If you select the first TextBox, find its PreviewKeyDown event in the Properties Box and double click it, this will create your skeleton handler. If you then find the PreviewKeyDown events for the other TextBoxes in the Properties Box, you'll see that there's a drop down box from which you can select the handler that you've created thereby wiring up all the TextBoxes to the same handler.
