用户控件不会触发访问者的事件

This UpdatePanel is contained by an UserControl. When the LinkButton is pressed arow should be added in another GridView. When an user is logged in this control is working well. The problems appears when an user is not logged in and try to push that button. No event triggers. Someone suggested me to give a permission for accessing this control in web.config. That didn't work. Anyone has another idea?This UpdatePanel is contained by an UserControl
