I'm guessing you're adding/removing items from a ListView that's being
displayed on the page.
The solution to this is to do a .SuspendLayout while you do the update, and
a .ResumeLayout(false) when you're done updating the box.
Sometimes this isn't always an option as you want to have "live" data in the
ListView, but in cases where you're updating every "so often" it should work
just fine for you.
