thank you for your reply. I spent some hours investigating this issue. Something funny is going on.
When I uploaded the master page for the project, it contained a commented-out sectionof old html code like this:
<!-- <telerik:radscriptmanager ID="RadScriptManager1" runat="server">
<telerik:radstylesheetmanager ID="RadStyleSheetManager1" runat="server">
<telerik:RadPanelBar ID="RadPanelBar1" Runat="server">
<telerik:RadWindowManager ID="RadWindowManager1" runat="server" Skin="Telerik">
This code should have no effect on how the page is being processed. In VS2008 it is shown as commented code.
But I just checked: the commented out controls are still beig rendered on the page output, and this happens in SiteFinity, as well as also in the old website project prior to us moving it to SitFinity. ASP.Net renders the 3 Telerik controls, I can see them in the trace list of the page, despite the fact that their declarations are commented out.
So now the answer to your question whetherI have a scriptManager control on the page is: yes.
But now, when I remove this commented html code, SiteFinity throws an error on every page:
The control with ID 'RadPanelbar1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.
It turns out that "RadPanelbar1" is the control created by SiteFinty for the navigation control included in the Template.
With the commented-out code in place, I find 2 controls RadPanelbar1 on the page, one is the navigation controlrendered by SF,the otherone is th control rendered because of the commented-out declaration.
Please let me know if you need more details on this.
