I have a few random questions that i am not able to find elsewhere

Hi everyone. I would like to thank you in advanced for taking the time to answer my questions.

First I am creating an ecommerce web page. On one of the pages I have the information comming from a database to display the related items. My problem is with catagories that have a lot of items for some reason when the page loads it creates my table about halfway down the page. The more items the farther down it starts. Catagories with a few items start almost at the top where i want them to. The code is coming from a code behind page. When i look at the html after the page is rendered there is nothing there that would contribute to the items starting halfway down the page. Anyone know why it does this?

Second is there a way that if the user closes the webpage or goes to another site completly that i can have the webpage delete some database entries?

Thanks again.
