wpf to handle touch keyboard in windows 8 desk mode.

i have a wpf app running on surface pro. since there is TextBox control for input requirement in GUI, i would like when it's tapped/focused, the touch keyboard can be automatically lunched and when focus is lost, the keyboard is gone.

Is there something i can do with wpf TextBox control attached properties to hook it up with the touch keyboard?

Thanks,

All smooth

smooth connection
