Adjust the tabel height in an ASP.NET page

Hi all,

I have an ASP.NET page that has three tables. The first is the page title, the second is a data area and the third is the message area.

The first table (title) and the third (messages) has a fixed height. But, the second (data), should have its height adjusted to the maximum possible for all three tables shown in the same screen.

I post below a sample code of ASP.NET page, that can be changed by anyone to demonstrate the solution of the problem.

Thanks, Marcelo Camarate

Hi Farred,

Thank you for your quickly reply. But, apparently, don't worked. The cell that would to be adjusted according to the screen height remained unchanged.

Any other ideas?

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

Sorry for the unintuitive class names. I moved the inline styles to classes and used jQuery to compute the height of the middle table cell. It works pretty good.
