Can you remove the vertical scroll bar?

I think the topic say it. I still require the horizontal scroll bar though.

yes you can.. i dont remember how... put "disable scroll bar html" into google

In the style section by:
.active-scroll-bars{ overflow-y: hidden }

Or the script code by:
obj.setId("ObjId");
var Mystylesheet= document.styleSheets[document.styleSheets.length-1];
Mystylesheet.addRule('#ObjId .active-scroll-bars', 'overflow-y: hidden');

Can you do this to 1 grid when they are using the same style sheets?

With the second one "Yes", because the "Id" is unique for each grid.

Ah ok in code it is then :)
