You need placeholders like asp:panel, or even another datalist to add your datalists too. But, the basic idea is that, on the button click event, you instantiate a new datalist with controls, and add that datalist to the placeholder.

If there is a well-defined # of datalists, then you could put them in updatepanels and make them visible or invisible after the buttonclick.
