I do not think I could find a definitive answer to this question, so I will ask him here. When is ScriptManager needed (or ScriptManagerProxy if using ScriptManager on the main page)?
For example, let's say that I have a ScriptManager on MasterPage:
If I have a web content form containing an UpdatePanel, is ScriptManagerProxy needed?
If I have a web content form containing a user control and this user control has an UpdatePanel, does the user need a ScriptManagerProxy?
If I have a web content form that contains an UpdatePanel and UserControl that also contains an UpdatePanel, do I need a ScriptManagerProxy user control in the web content form?
Thanks.
