loadondemand problem with updatepanel

[Mojtaba]

I am using a treeview in updatepanel. When I try to rebind tree all node texts is cleared, and just (+ -) icons remind.
I have Q1 2009 and use load on demand with ServerSideCallback option. I read this topic but there isn't answer:

Thanks.

Hi Mojtaba,

You should either use ServerSide ExpandMode instead of ServerSideCallBack as the UpdatePanel will take care of transforming the postback into a callback, or remove the UpdatePanel and thus use the built-in callback mechanism of the treeview.

I changed load on demand to ServerSide but problem does not solve and turn load on demand off, but problem exist.
I understood that just IE has this problem.
How can I update tree without update panel?
any idea?

Update IE7 to IE8, and problem solved.
