Q: 

Sys.InvalidOperationException: Could not find UpdatePanel

Hi,

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 ?

Regards
