Disabling Submit/ reset button

Disabling Submit/ reset button

In my application I am using a form in which a decision check box is used to trigger 'send mail'. This mail is actually a report between a 'From Date" and 'To Date' , which are two fields in this form.

However, I do not need to store these 'From Date' and 'To Date' data once mail is sent, that's why I would like to disable submit/ reset buttons.

Is it possible?
