How do I keep the expanded child grid views visible on postback

I have a form with a collapsable editable nested gridview. When I try to edit the items in the child view a postback occurs which collapses all the child gridviews. I looked at some other posts on the web, but couldn't figure out how to get it "remember" which child views were expanded and open them again after a postback.

Hi,

expanding and collapse panels is only client side(javascript) actions .

I hope you know that asp.net don't maintain javascript actions.

But

If you use Jquery it can achieve .

on every action you've to post that action to server and maintain that data in session.

And then in pageload check that session data , set styles and properties to panels

I hope you understood what I said

All the Best
