that error in because working within page inherits master , have 2 scriptmanager declared.
for sure have , scriptmanager within site.masterand adding scriptmanager in page (default.aspx) too.
remove scriptmanager within childpage, because page going utilize site.master's one.
remove:
<asp:scriptmanager runat="server" id="scriptmanager1" enablepartialrendering="true"/> c# asp.net asp.net-ajax
