Hi prady,

Your web application is running in Medium trust. However RadAjax "Prometheus" has some limitations when running in medium trust. To make it work you  should  change  the base type of your pages that use radjax from "System.Web.UI.Page"  to "Telerik.Web.UI.RadAjaxPage":

Before:

public partial class MyPage : Page

After:
public partial class MyPage: RadAjaxPage

Hello,

We are trying Prometheus and are facing the same problem.

We are developing a DNN (DotNetNuke) module and thus, we cannot simply change the page's base class (the module's controls Inherits from Entities.Modules.PortalModuleBase).

How can we solve this problem?

Thanks in advance!

[Steve]

Hi guys,

This is just a follow up to let you know that we've made the necessary adjustments and exposed a new property, which can be used when you run RadAjax Prometheus in Medium trust - RestoreOriginalRenderDelegate. By default it is true, if you need it in Medium trust, you should set that to false (it would be documented in Q3 SP2).
Find attached the latest internal hotfix to this thread including the new property.

Do let us know if you encounter any problems with it.

I got the same problem with my radgrid, on medium trust level on a server. Im using it with DNN 4.8'.

Where can i set the RestoreOriginalRenderDelegate value?

Thank you.

[Pavel]

Hello Patrick,

The RestoreOriginalRenderDelegate property can be set on RadAjaxManager or RadAjaxPanel control like this:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" RestoreOriginalRenderDelegate="false">
    <AjaxSettings>
        ...
    </AjaxSettings>
</telerik:RadAjaxManager>

Hi, I'm currently facing the same error. Could this have something to do with a windows update? Problem is that I have the error in a DNN modules, so I cannot change the Page class as suggested in this post. Is there another fix that works in DNN?

[Sebastian]

Hi Rutger,

Try setting the RestoreOriginalRenderDelegate property to false as suggested in the last post and let us know whether this helps. Also verify that you are using the latest version 2008.2.1001 of RadControls for ASP.NET AJAX.

Thanks again stephen!

Hi

Do you only need to set the property on the AJAX manager on the master page? What about the proxies on child pages?

Also, which class should the master pages inherit from to fix this problem?

Regards...

[Kashan]

Hello Telerik team,
i also got the same problem and the massage was occur that " not enough permoissions..." and i made the changes as you told ie "System.Web.UI.Page"  to "Telerik.Web.UI.RadAjaxPage" now the page show on server but there is no loading panel display when i trigger even the page refresh, like there is no ajax it is running very smooth locally
Please help me what to do... reply soon

What if you are using Master pages. Is there a class for that.

[Sebastian]

Hello Hector,

It is enough to have your content page inherits from RadAjaxPage. Thus RadAjax controls which are either on your master page or the content page/user control inside the content page should work without issues under Medium trust environment.

Hi,

I am using Q2 2008 controls but they wont work with my shared hosting provider.  I've inherited from the RadAjaxPage but this doesnt solve the problem.

The controls are visible but they don't dropdown/expand etc etc.

Was there any fixes for this?

I've used the latest trial of the controls and they work ok but I can't afford them and would expect the ones I bought to work just fine.

Thks

Phil

Hello phil doc,

Is it possible that some javascript errors on the page conflict with the client initialization of some of your RadControls and cause the erroneous behavior? Please address them if any, this should not depend on the versions of the controls you are using.

The exception discussed here is generated on the server and the page fails to load at all in this case.

Kind regards,
Sebastian
