also enable ascx control cache. when page first loaded ok, when page getted server cache script references missing...
i search lot , can't find idea. so, problem scriptmanager not generate script reference when control loaded server cache.
this bug outputcaching , script manager, officially recognized microsoft
there workaround add scripts scriptmanager manually:
<asp:scriptmanager id="scriptmanager1" runat="server"> <scripts> <asp:scriptreference name="ajaxcontroltoolkit.common.common.js" assembly="ajaxcontroltoolkit" /> <asp:scriptreference name="ajaxcontroltoolkit.extenderbase.basescripts.js" assembly="ajaxcontroltoolkit" /> <asp:scriptreference name="ajaxcontroltoolkit.textboxwatermark.textboxwatermark.js" assembly="ajaxcontroltoolkit" /> </scripts> </asp:scriptmanager>
