The control with ID 'RadScheduler1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

Hi all,

I need to use the Telerik Scheduler (AJAX) component in my application, so I created a user control and a page to hold my user control.

I dragged the Telerik scheduler component from the tool box to the page, and when I run the application and view that page, I see the error:

"The control with ID 'RadScheduler1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it."

So, I added a ScriptManager to the top of my user control, then when I run it I got the exact same message.

I then removed the Telerik Scheduler control, leaving only the Script Manager, and when I ran the project it told me:

"Error loading user control: Only one instance of a ScriptManager can be added to the page." !

When adding the Scheduler to a blank project, it works perfectly. But when I try and run it within the Kentico framework it bombs.

What am I doing wrong?

RE:The control with ID 'RadScheduler1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

the ScriptManager controls already exists in the PortalTemplate.aspx
<form id="form1" runat="server">
<asp:PlaceHolder runat="server" ID="plcManagers">
<cms:CMSPortalManager ID="manPortal" runat="server" />
<asp:ScriptManager ID="manScript" runat="server" ScriptMode="Release" />
</asp:PlaceHolder>
<cms:CMSPagePlaceholder ID="plcRoot" runat="server" />
<asp:PlaceHolder runat="server" ID="plcLogs">
<cms:QueryLog ID="logQuery" runat="server" />
<cms:ViewState ID="viewState" runat="server" />
</asp:PlaceHolder>
</form>

RE:The control with ID 'RadScheduler1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

When I add the Telerik control, I get a message that reads:

"The control with ID 'RadScheduler1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it."

How can I add the control to the page and get it to work?

Jason

I added the RadScriptManager to the page, then removed it, and now the RadScheduler works. Very bizarre, but it's running now, thanks!
