All of these controls work through the Nucleo.Web.NucleoAjaxManager. Like the <asp:ScriptManager> control, this control is the lifeblood of this framework, meaning that each page that uses the framework must define this control. Please make sure you include
a reference to this control, ideally in the master page file. Simply use a reference that looks like the following:
<n:NucleoAjaxManager id="nam" runat="server" />
For more information on this control, see the documentation specific to it.
