Add footer in datagridview

Hi,

I am working on web application also.

In that form I have two textboxes firstName and lastName and one Button ADD.

When I am entering details of one person at that time I also want to add the details for another 2 persons also in that same form (dynamically).

Means I will press button ADD. on that add button i need two another textbox with same label like firstName and lastName. Like wise, i want to add textboxes as i required.

So, how is it possible...?

I have some idea that this problem is solved by adding footer to gridview. But how to do that I don't know.

And if there is aonther solution otherthen this then that one also tell me.
