creating a favourite list in asp.net

I am displaying albums with images and other text in a gridview. I want to add a functionailty like shopping cart. The idea is that there would be a small image in each row of the grid. If the user clicks it the id of that album is added to the list. Also i would mark that row as being added to the list. Can anybody have any ideas or code that can help me in this.

You can add an ImageButton control to a template column in the gridview. Handle the click event of this ImageButton in the ItemCommand event of the Gridview.
