How would I validate only those controls which are on the users screen.
So if a text box is on screen it must have text in it. If a drop down list is on screen it must have something selected (not blank)
I have put an example here - yes I know the JS is very simple (I did this to show just the method)
If you load this you can see the problem
Thanks
