            </dx:ASPxPopupControl>
        </dx:PanelContent>
    </PanelCollection>
</dx:ASPxCallbackPanel>

if i put 2 user controls in a page with reference ofcourse... only the last one will popup and work... first one doesnt popup on click... i think somethings wrong with the callback.. eny ideeas?

You see this issue, because you have two ASPxCallbackPanels with the same ClientInstanceName. In this case, the PerformCallback method of the last panel is called.
A possible solution is to define the CallbackPanel's ClientInstanceName dynamically. Also, you will have to use a server side DIV element to set its onclick event in code behind.
