Can anyone help me figure this out? I have a dataset that lists books with info on the books and ratings average from users. I have the books data listed on a repeater for users to look through and give ratings if they liked the book or not. I am stuck on filtering the repeater to only show books that the user hasn't rated yet when they enter the page. Having the book disappear from the repeater once rated would be great to have also but it's not that important. keep in mind that the dataset of books will hold over a 1000 books and I am expecting to have at least a few thousand users. Any help will be greatly appreciated.
