Hey thanks for the reply, I think I remember reading somewhere that the MCPD exams are going to be retired in July, do you know anything about this??

If you are interested in executing a certain block of code irrespective of whether an exception occurs or not and still worry about catching an exception you might use the try-catch-finally block. Even if a goto statement is present in a try block, the control gets transferred to the label in the goto, only after executing the finally block. You should try and use them in your code as much as possible, especially if you suspect a particular error may crash your programme. Comm100 - Leading Live Chat Software Provider

Validation against pre-fetched values is a heavier operation than server-side validation. You should just go for the latter as a much better standard ;) It will be one short post instead of sending a whole list of records into the browser.

Ok thanks very much il do some research on them. Cheers
