How to make 2 buttons on a repeater not link to the same place?

I have a repeater on my site for a list of different items and I want my customers to be able to click a button to view more about the item but all of my buttons have the same link because they are on a repeater, can someone please help? thanks:)

Is it connected via the editor UI to the dataset, or do you bind the data by code? Do you store a different link to each item (in the database collection)?
