Show Scrollbars On DataGrid

Is it possible to have scrollbars show on a datagrid please?

I've not set the layout width property of the datagrid & set the header columns not to wordwrap & to be 1000 pixels wide, but the site automatically formats the control to fit onto my webpage, I'd like to be able to scroll left & right.

Thanks!

I've hunted around a little bit & found the following property I can set:

style="overflow:auto"
style="overflow:scroll"

This makes the scrollbars appear for the asp datagrid at design time, however at runtime, the datagrid control is sized to fit the table column it's placed in, squahing the solumn headijngs still.

The next part/question on this then is... can I specify a fixed size for a single column or all of the columns at once with the datagrid control please?
