telerik template combobox will not open in rad window

[Jeff Wickersham]

I have a radcombobox control on a pop rad window on a web server that will not open to display the items.
It does work on my laptop though
What is the work around?

Hi,
I was not able to replicate the issue. Here is the sample code and screenshot.
ASPX:

<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
 <Windows>
 <telerik:RadWindow ID="NotifyDialog" runat="server" Width="900px" Height="760px">
   <ContentTemplate>
     <telerik:RadComboBox ID="RadComboBox1" runat="server" AllowCustomText="false">
       <Items>
          ...... .... ....
      </Items>
     </telerik:RadComboBox>
   </ContentTemplate>
  </telerik:RadWindow>
 </Windows>
</telerik:RadWindowManager>
<asp:Button ID="btnopen" runat="server" Text="open" OnClientClick="return ShowNotificationForm()" />

JS:

function ShowNotificationForm() {
     window.radopen(null, "NotifyDialog");
     return false;
  }

Hope this will help you.
Thanks,
Shinu.

Shinu,
Thank you for the input. Perhaps I need to explain the situation better.
So I have a page that the radWindow is actually opening, in that page there is a templated combobox and an upload control.
When the user attempts to open the combobox it will not reveal contents.
Now the funny thing is that it works fine on my dev machine, windows 7 visual stuidio 12, any browser, framework 4.5
But will not work on production server running iis 7, framework 4.5

Here is the calling page snippet
   <telerik:RadScriptBlock runat="server">
            <script type="text/javascript">

So when running the page using fiddler I get this 500 error
http://ccworks2/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=RadScriptManager1_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bAjaxControlToolkit%2c+Version%3d4.1.40412.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d28f01b0e84b6d53e%3aen-US%3aacfc7575-cdee-46af-964f-5d85d9cdcf92%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2013.2.611.45%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3a9711a23a-6cf5-4e6c-87f5-29e6585b3026%3a16e4e7cd%3af7645509%3a2003d0b8%3a24ee1bba%3af46195d3%3a1e771326%3aaa288e2d%3aa585d0d4%3a874f8ea2%3a2a2fc429%3a68f76a79%3a7165f74

what is all this indicate?

[Marin Bratanov]

Hello Jeff,

Once I ran the page from the attached snippets things seem to work fine with me (without the dependencies I cannot emulate, of course). Could you compare what you have with what I have attached and try to find the difference that is causing the problem?

On the error you get I can suggest the following:
- see if using the scripts CDN we offer helps
- make sure you are using the latest version (Q2 2013 at present)
- try disabling the script combination from the RadScriptManager to see which is the exact resource that fails (EnableScriptCombine=false).
- use this blog post to find the offending resource name and see if replacing it with an external reference as shown here helps
- go through this help article on troubleshooting server errors with webresources (especially the last part) and this one on general troubleshooting.

And, to answer the last question - this indicates to me, that there is an issue with loading a script in the content page in the RadWindow and not in the RadWindow control. I hope the above ideas will help you resolve it. Having a broken script is likely to cause JS errors that can break our controls and the combobox does not open because of this, I think.
