TabContainer height dynamic

[Mark]

Hi,

I use TabContainer from asp.net extensions.
Inside of TabPanel I have divs which size (height) is dynamical.
Sometime it increase sometime decrease.
I see the property of TabContainer "Height" and I can set it.
But I would like TabPanel to grow or shrink when div inside grow or
shrink.

How to make TabPanel's (in TabContainer) height dynamic ?

Thanks for help
