It depends on what you mean by easy, and how big your items are. You can just store them in the session context if they are small enough, otherwise, you'll have to monkey around with retrieving just the result set you want. I typically use a link to an action, with a parameter called page. Page can be next or previous. If it's next, I take the next pagefull and put it in the list to be displayed. Typically I use the same action that grabbed the list to begin with, so that if the list grows larger then can be stored in memory I can easily modify the code. I also typically use two session variables, one is the entire list and one is the list to be displayed. This supports modificatio to an entirely DB centered list ( don't need to use the entire list session variable). --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
