RadScriptManager Error

[Robert]

I placed a RadScriptManager control in the Masterpage of my Sharepoint site. Here is the relevant code:

<telerik:RadScriptManager Runat=server id="RadScriptManager1">
    <Scripts>
        <asp:ScriptReference name=""Assembly=""Path="~/Scripts/jquery.getParams.js">
        <asp:ScriptReference name=""Assembly=""Path="~/Scripts/jquery-ui-1.7.1.custom.min.js">
    </Scripts>
</telerik:RadScriptManager>

I am following examples set here and here.
However this generates the following error:
Literal content ('<asp:ScriptReference name=""Assembly=""Path="~/Scripts/jquery.getParams.js">
<asp:ScriptReference name=""Assembly=""Path="~/Scripts/jquery-ui-1.7.1.custom.min.js">') is not allowed within a 'System.Web.UI.ScriptReferenceCollection'.

I am not sure what this is.

Hello Robert,

I suggest the following:

1. Remove the empty Name and Assembly attributes so the declaration looks like this:
   <telerik:RadScriptManager Runat=server id="RadScriptManager1">
       <Scripts>
           <asp:ScriptReference Path="~/Scripts/jquery.getParams.js" />
           <asp:ScriptReference Path="~/Scripts/jquery-ui-1.7.1.custom.min.js" />  
       </Scripts>
   </telerik:RadScriptManager>
   It seems that for some reason the ScriptReference tag is not closed in our documentation. I will make sure we fix this ASAP.
2. Make sure the following line is present in your web.config:

<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

I have updated your telerik points for spotting the problem in our documentation.

I hope this helps,

I have made all the changes you suggested and am getting the following error:

System.NullReferenceException: Object reference not set to an instance of an object.

If I remove the RadScriptManager tag and replace it with a standard asp.net ajax ScriptManager my page loads fine. But I need the RadScriptManager in order to do what I need.

Hello Robert,

For some reason the HTTP handler detection code fails in your setup. You can try setting the EnableHandlerDetection property of RadScriptManager to false. Additionally please make sure that you have included the assembly version when registering the HTTP handler in MOSS as explained in this help topic.

Hi Albert.

That was the problem. I followed the HTTP handler instructions in the original documentation page which is different from the one you just sent. That original page is pretty messed up.

It's all working now. Thanks for your help!
