If you have a backup with Time Machine, that may be help. However, if there is no backup with your computer, you can try ipad data recovery software to find back all your lost files in trash bin. One more important thing, if you want to recover them back, you need to make sure that the data hasn't been overwritten. If it has, there is no opportunity to get back your lost files.
Sounds like you're thinking that an iPad has a "trash can" like a Mac does. As mentioned by King_Penguin above, this is not the case. Once deleted, files (such as photos and videos) are not moved to a user-accessible "trash can" or a temporary holding area until you decide to empty it.
Emails do however use a "trash can" environment but this has to do with how emails are handled by your email provider.
