How to retain the Menus in Post BAck

Dec 6 2005 4:50 PM
Hi,
I am using C3 with asp.net and my left and top menus will come from an .inc file, when the page is loading for the first time, the menus are getting dispalyed properly, but when i select any radio button which will trigger post back event this menu is getting invisible.

Can any body suggest me how to solve this.
thanks in advance
