Same way as you did for the width. Set the Height property to 100%.

 Please note that setting height in percentages didn't work in few pages, I am unable find out why that is happening. We set the height in pixels as workaround.

Thanks for your previous post. It worked fine.

Now, I have a second question: When the bound datatable does not have rows, the webgrid has the expected width but the height is minimum, like a centimeter or so. I'd rather have the grid to have about the height of the screen in these cases; how can I accomplish that?

Thanks a lot.
