Dynamic datalist height

I have a datalist and I want the datalist to grow from no recors to fill the
screen, but not go beyond the screen height. How do I do that?
I've implemented the scroll bars but that's for the fixed height. I want
the datalist to grow and shrink and never go beyond the current screen
height, if it goes beyond the screen height I want to implement the scroll
bar.


Thank You

Here's my code, I've tried adding a table, but still can not get it to work.
