One thing that I think is also related to a scroll somehow.

I've got thousands of rows in my table and when they are all already preloaded (no additional auto load happens on scroll), I notice a slight delay when I try to move a scrollbar with the mouse. Scrollbar doesn't move for at least 2-3 secs, it looks like it is undergoing some intensive calculation. After it starts moving, scroll becomes smooth again. But if I release it and try to drag the scrollbar again, interface hangs for some time again.

When new rows are preloaded on scroll such delay maybe understandable, but I do not see why it can be happening when all rows are already loaded. This makes the interface to look a bit sluggish.

Anyone any idea of what can be the reason for this and how to eliminate it maybe?

@toolm, but as Tony said this will introduce new problem – last page won't be retrieved at all. Is this not true in your case?

I wasn't thinking of fixing this in such way at all. Initially I was planning to do a reset of some kind after a change in grid height, but didn't know what to reset and where? I was hoping that it is somehow possible to accomodate scroll size to a new height maybe…

What you guys think?

When you add an altRows:true to your options object, you get .ui-priority-secondary class on every next row, you can add a css rule yourself, at least that's how I do it.

But my problem is little different. altRows option works good at first, I get zebra grid, but it doesn't keeps it that way after sorting operation on any column. Rows get messed. Is there any established way to deal with this “issue”?
