Need advice in setting column's width of a grid inside a repeater

[Guest]

Dear All:
Banckgroud: I have a datagrid which lives inside a repeater. Which is
working fine. What i need is to dyanamically set the column width of the
grid (which lieves inside the repeater). Is there any way, we accomplish
this? Any advice on this would be greatly appreciated.
