Making a grid invisible

Hello,

does anybody know, if it's possible to make a grid invisible or visible (like gird.setVisible(false);). I can't find a method for it, is there a other way!
Thanks a lot,

Kim
BTW: ActiveWidgets seems to be super!

<script>
function hideGrid() {
obj.setStyle("display", "none");
obj.refresh();
}
function showGrid() {
obj.setStyle("display", "block");
obj.refresh();
}
</script>

By the way, why do you want to hide this super grid ;-) hehe, kidding...

A good question...!
Thanks a lot!
Kim
