Validate UserControl elements on Parent Page button click

I have a usercontrol which has few textboxes and associated validators. (This is for holding common form fields which i include at multiple place.)

This usercontrol doesnot have any buttons.


The user control is included inside a page. The page has other textboxes and a submit button.
How do i ensure the the forms in usercontrol is valid when i click the submit button outside on the page?


Thanks and Regards
