ASP2 ImageButton renders unwanted Style Tag

[Duncan]

Good morning,

I'm trying to use a CSS Class to control the border around ImageButton
controls (Red for selected, green for available, etc) without any luck.

The problem seems to be that the ImageButton control always renders a
'style="border-width:0px;"' tag, which takes precedence over any
CSSClass="" tag which I supply. This happens even with the minimum
details required to make the tag appear and I can't see a way of
turning it off.

Any help greatly appreciated.
