To reduce trips to the server we want to do some validation clientside. I'm able to access the values of asp:textboxes on the clientside but cannot access checkboxlist. I need to verify whether individual check boxes have been checked before the form is allowed to submit. I have tried several approaches but usually get an error indicating that the object I'm trying to access is null or does not exist. Can elements of an asp:checkboxlist be accessed clientside, and if so how?<BR>Thankyou in advance for any replies.
