"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databo

[moi]

Hello,
With ASP.NET 2 ,
i have two dropdownlist, one "A" (not in a formview) in the web page and other one "B" in a Insert Template in a formview. There's a link (parameter between this two dropdownlist.
When i selected a new item in the A dropdownlist, i have this error message :
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control"
when i disable EnableStateView for the formview, it works ....
Do i have to continue like that ?
another idea ?

thanks a lot !
