RadWindowManager not finding the pages ScriptManager

[Sigrún Eva]

Hi all,

I'm having a problem with the Q2 version of RadWindow for ASP.NET AJAX, I was updateing the binaries from Q1 to Q2 and now I get an errormessage

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

I'm using the ToolkitScriptManager from the AJAX Toolkit on CodePlex and I am using the most recent version of that as well.

I'm building the solution with DotNet version 3.5SP1

If anyone can point me in the right direction that would be greatly appreciated.

Hi,

Error message "The control with ID '[ControlID]' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it."

This error occurs when you have added a control from RadControls for ASP.NET AJAX to a page which does not contain a ScriptManager control. To resolve that error please add a ScriptManager control to your page:  <asp:ScriptManager ID="ScriptManager1" runat="server" />

 You can also refer the following help article.

Thanks

I'm having exactly the same problem, but its more complicated than not having a ScriptManager on the page.

I have defined a scriptmanager on the page, but I still get this error from

Telerik.Web.UI.ScriptRegistrar.GetScriptManager(Control control)

More interestingly on Page_Init I can get reference to the scriptmanager using the static method:

ScriptManager.GetCurrent(this);

So if a scriptmanager exists why does the RadControl have trouble referencing it?

Any ideas?

Just checking, you are using the RadScriptManager, right?  I've done that a few times, using the regular ScriptManager after adding some Telerik controls and having no clue why stuff wasn't working correctly. :)
