Windowshade type control??

[CK]

Does anyone know if there's a control that does winowshading? We want to
have an expandable/collapseable control. When it's expanded it will contain
a gridview, and when collapsed it will have some info in it , like rolled up
items it contains, like if it had trips and trip costs, we would want to put
like the number of trips and the total trips cost in roll up mode. Anyone
have any ideas where I could find a control similiar to this. Preferably a
control that comes with Visual Studio.

Thanks,
