How do I tell if transferring purchases from Ipad to PC worked?

Thanks, but that was the page I was working from to transfer purchases originally. I followed the directions for the section that starts, "If when you connect your device you are not prompted by the dialog above..." But it doesn't explain how to confirm if the files were actually transferred, which I need to find out since iTunes is giving me the message that I still need to transfer purchases before updating.

Ok, so my purchased apps are all appearing in my library. So why am I getting that pop-up message that I still need to transfer purchases when I try to update the I.O.S.?

I did that, but unfortunately I am still getting the same popup message. Am I supposed to reset my ipad first? I think on the top of the Apple update instructions page it said something about needing to erase and and reset if I am updating from less than I.O.S. 5.1, but I didn't know how to do that and the initial prompt to update on the iTunes page didn't give me that option first before I got the popup. Is there some other way to update from iTunes?

Thanks, but my iTunes page does not look quite like that. It does not have the version box. Instead, in the right side of the top box where it lists info about the Ipad it says I have I.O.S. 4.3.5. and says a newer version is available and has two boxes - "Update" and "Restore iPad..." If I click the Restore one, will it erase my current apps from the Ipad? And if so, is that what I should do? (is that why I keep getting the popup message - because they are supposed to be erased?)

please see my updated question... but anyway, in regard to your answer, I thought I was supposed to pick the erase and restore option, since I have an older i.O.S.?

Ok I just tried that and I got the same popup message about needing to transfer purchases to iTunes Library. I don't understand why it would say this if the purchases were indeed transferred and it was going to wipe them out from my iPad anyway?

Thanks. I had already done the backup. So do you think I'm safe? I don't understand why Apple says "To update your iPhone, iPad, or iPod touch from iOS 4 to iOS 5 or later, you must erase and restore your device first, before completing the update" on the top of the page I linked to. Am I supposed to do that manually or will it do that automatically when I choose either "update" or "restore"?
