asp.net forms ScriptManager __doPostback

Question

Hi,

Why does the ScriptManager ALWAYS insert the __doPostback method in javascript, even on an empty page where no controls can cause a postback?

Thank you

It is because by default ScriptManager assumes partial rendering. You can disable it like this:

<asp:ScriptManager ID="sm" runat="server" EnablePartialRendering="false" />
