如何防止自定义ajax工具包编辑器中的ctrl-v？

Hi I have succesfully made a custom ajax toolkit with a few buttoms in the footer toolbar as I wish. Now I also want to avoid crtl-v and right-click paste, but have searched, searched and tried everything with no result ... Maybe someone can lead me on the right track, I hope :)Hi I have succesfully made a custom ajax toolki
