 Sys.InvalidOperationException: Could not find UpdatePanel
Since i migrated my website into a web application, the UpdatePanel's does not work ...

    Message : Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl01_CPHColonneGauche_Moteur1_UpdatePanel1'. If it is being updated dynamically then it must be inside another UpdatePanel.


I tried to set the UpdateMode to Conditionnal but it does not work

Any idea ?
