The Grid is refreshed using a timer. The expanded groups keep their state across callbacks.

"I'm pretty happy on replacing ComponentArt's splitter with yours, I'm getting vastly superior performance out of it. On resize of the CA splitter it can take 2-3 seconds to complete a resize of a complex page whereas yours is maybe .5 of a second max."
