New Address creation on Shipping Page

Hey All,

I have a .net user control running on the shipping.aspx page that retrieves the selected address from the drop down list or radio button of addresses in the users account.

This works great for existing addresses and I can save the info.

How can my control know what the address ID is when the user adds a new address? I get the order.GetShippingId it always has the value of the last selected address when adding a new address or 0 which is no good.

Any suggestions on how I can figure out what address ID has been assigned to the new address that was created?
