on mouse hover show small window with update & cancel

Question

Hi 

I'm creating a order Items listing page where item image, Item name, Quantity in text box, update button under Quantity text box, price next to Quantity text box, sub-total (quantity * Price), delete button will be shown in a row, this will repeat for all Items.

If user wants to update Quantity, on focus on Quantity text box, cancel button should appear next to Quantity text box (there will be a empty space initially between Quantity text box & Price).

Once user changes the quantity for a item and click on update should change the sub-total. If user changes the Quantity and click on Cancel, nothing should happen

If I use Gridview / asp:repeater controls should I be able to achieve on mouse hover functionality? if so, please lead to implement this...Thanks in advance.
