resizing a datagird

[pato.llaguno]

hello,

I have a datagird inside a "main" div, this is the main thing on my page, the rest is only a header and footer, I want for this header and footer to be static size, and that the datagird will take the rest of the space. the footer and header together add up 227 pixels, so i am trying to do browserheight - 227 will give me the desired height on datagrid, but i just can't find how to actually change it via the methods or properties.

Thanks!
