Lets say for example I have a (variable length) 2 dimensional array of product names and their unique product codes. I can display this list in a datagrid, table etc. (Imagine this as a standard shopping basket type scenario)

What I need to do is be able to tick multiple items (?) , then on clicking a submit button, fire an action.

The bit im struggling with is how do i: A: programatically display asp:checkboxes for each item (and give them a unique ID) B: know which are ticked on firing the final action

(not sure if this question is best suited to the main stack but theres so much activity on there that questions just get lost now!)
