I have table with a large number of columns that I'm NOT allowed to modify.  The columns can be categorized by patient, procedure, diagnosis, etc.  Rather than try and jam all the columns onto a single maintenance form I wanted to create a form that uses a panel manager with a page for each "category" of data.  I'd use a themedlinkmenu for navigation between the category page.  Before I design the form I have some questions on how the error provider will behave. 

When a Save is performed, how will the error provider which is defined at the form level react?  Will it show only the errors on the current (visible) page?  What if there are no errors on the current page but there are on other non-visible pages?

Thanks!!
