Using CollapsiblePanelExtender/any alternative Control within Gridview(binded with database) to expand and collapse data

Question

I want to use CollapsiblePanelExtender Control within GridView, and that GridView is binded with database

Actually, what I am trying is :

1)    GridView is showing name of list of the employees, and when I click on the name of a particular employee, whole details of the employee(gets expanded) will be shown inside Panel or anything suitable, and again when I click on the Name (details get collapsed).

2)    Expanding and collapsing can be multiple too, i.e. when I click on 2 names, then both the employee details must be expanded unless I collapse any of them.

I am not getting the idea, How and what to use for this problem. Can anyone help me out with this problem.
