My WPF app uses a dialog with Ok and Cancel buttons. I would like to bind the Enter key to the Ok button and the Esc key to the Cancel button. Seems like it should be a simple thing to do.
Try setting the IsDefault property on the ok button to true, and the IsCancel property on the cancel button to true.
