In ASP.NeT Form, I want to show/hide 3 panels with click of 3 buttons

[arti]

In Asp.net form, I have 3 panels. I want a button on top of each panel to hide or display the panel. I am able to do it. But when there is any postback, the page loads with its design time setting- all panels are visible=false.
On each panel I have a submit button and asp.net List with autoPostBack=Tr ue. So the form will postback to server.
I want that if a panel was open at the time of postback, it should be open at page reload.
Pl help!

Maybe save the panels visible property in Session & retrieve accordingly.

Thanx, I'll try that.
