problem with 2 groups of validation controls on 1 page.

[Paul]

Hi I have 2 groups of controls on one webform and many of the controls in both groups have validation controls assigned to them. I have a corrosponding submit button for each group but need to isolate the controls and validation as currently when I click either of the two submit buttons all of the controls on the page are checked for validation. Is there a way to group the controls perhaps in a panel to isolate the two groups?
Thanks
