Apply Move Effect To List

I have give some example coding in below image
in that just give dataprovider to horizonatal list and apply some login for next / previous /paging
it's give moving effect to list

mxml Syntax for moving

"< "mx:Move id="eff_project_move" duration="500" easingFunction="{Exponential.easeInOut}" target="{box}" /">"

"<" mx:Canvas ">"
"<"mx:HBox id="bx" moveEffect="{eff_project_move}">"
"<"mx:HorizontalList id="lst" columnWidth="323" /">"
"<"/mx:HBox"> "
"<"/mx:Canvas">"

and In any button Just put syntax like

bx.x = bx.x - lst.columnWidth;

for moving next 1 record
