Restricting the user not to paste,delete or update content in iframe

Hi,

i am having a text editor which uses iframe. Here if the user is trying to paste some text into the iframe, how i can restrict the user not to do that. in the same manner, i don't want the user to delete the content from iframe directly. if the user is trying to do that, it has to alert the user.

One possible way is to make it read-only and only allow input via buttons.
