Hide White space from Hidden Controls/Divs

Hi,

I have a webform with multiple controls, and these multiple controls are either visible or not visible using the Visible=True or Visible=False.

The problem is, that when the button is hidden, there is a large white space where it was. I would prefer if the button beneath it took up that white space, so it moved up and took the place of the hidden button. Is there a way to set this up? I'm using Visual Studio 2008.

 thanks
