wizard control insertion

Question

I m using ASP.NET wizard control for member registration. There are 4 steps in the control. On Finish button click event I want to save the data in more than one database table. When I insert the data into the first table. I want to capture the id against the last insertion. and then insert the remaining data in to further tables. I don't know how i can do this. Please someone help me on this issue.
Thanks
