Dear Steve,
You responded to my message in another thread (Forum -- Medium/Partial Trust) by referring me to the thread on "Support for medium trust environment" but that one seems to have a fault (line 362 char 9 error: null is null or not an object thread ID 156745) so I cannot reply to it! I had already seen that thread but since no-one had bothered to reply to it, I decided to post to this one. Am I missing something, or should I take the lack of response to that thread as implying Telerik still has no response to this most obvious user requirement for Telerik Reporting to work on shared servers?

For anyone else searching for information about reporting packages that can be used on shared / hosted servers, ASPPDF has just announced a version of its software that will finally make the breakthrough. It is not yet in final release form but is available for download at www.asppdf.net. I'm sure we Telerik fans would prefer to see telerik respond to years of requests for this ability but, at least in the meantime, there is a well-respected package that is responding.

Best regards, Neil

In my earlier post on this thread I forgot to ask you the key question: is it possible for you to provide much more specific information about the trust requirements / limitations of the current version? Our website host is prepared to make changes to the server web.config if this would help but they have asked for more specific information to see what they can do - - their exact request is:
"Most software doesn’t need full trust, the development companies just say that to make it easy for them. We can use a hybrid of a role by amending the .net config. Do you have any details on modified trusts for the product you have ?"

Can you help? Neil

Hello Neil,

I'm sorry to hear you had problems with our webiste and forwarded your other thread to our web team, so they can look into the issue you've reported.
As to the medium trust environment support, although your host is probably correct for most software vendors, this is not the case with the reporting products. I've personally taken the time to test our direct competitors and they do not work under medium trust either. You can take a look at this fresh post that explains how they DO work, but at the same time have numerous limitations, two of which make the reports totally unusable (ability to use richtextbox, table item and of course export to PDF which is what 90% of people use reporting for in the first place).
We do not want to make any excuses, but providing out of the box medium trust support (with not a single permission required) for our product is not trivial at all, and our current goal is minimizing those requirements as much as possible. Believe me when I say that there is nothing that flatters us more than happy clients telling us how much they enjoy our product and appreciate the hard work we put into them. In this line of thoughts, we have the medium trust support in our TODO list with high priority.
And here are the current requirements, which hopefully will be less with two after the next release:

RegistryPermission
ConfigurationPermission
FileIOPermission (Read, Write, PathDiscovery - C:\Windows)
UnmanagedCodePermission
WebPermission (only if using PictureBox items with url values)

Thank you for the patience and understanding.

Kind regards,
Steve

Hi again, I'm using Q2 2009 SP1 and I'm getting this error... (above)

I supose this is the solution: "...rendering extensions require UnmanagedCode permission to operate at all times. Take that into consideration when deploying your application and if necessary disable those extensions to avoid security exceptions..."
Do you have code example to configure the web.config correctly?

Thanks.
Best Regards.

Juan Carlos.

Hello!
Sorry for using this old thread again but I get the exact same error as Juan.
I'm running Reporting Q3 2011 (5.3.11.1222), ASP.NET 2.0 and according to
my host the settings are Medium Trust.
I have added this to my web.config:

<configuration> 
    <configSections>
        <section
                name="Telerik.Reporting"
                type="Telerik.Reporting.Configuration.ReportingConfigurationSection, Telerik.Reporting, Version=x.x.x.x, Culture=neutral, PublicKeyToken=a9d7983dfcc261be"
                allowLocation="true"
                allowDefinition="Everywhere"/>
    </configSections>
    …
</configuration>
Any help or suggestions on how to solve this would be greately appreciated.

Best regards

Jan

Hello Jan,

In general when your application works in Medium trust you do not have to do anything special since the export dropdown control will automatically be populated only with the available extensions. There is no need to add the Telerik Reporting section, since on its own it does not do anything, it only makes available the Telerik Reporting configuration section. You will have to actually use the configuration section and change things in order to see any results in your application.

On the other hand if you want to restrict the users from exporting to certain formats that is the way to go, but you will have to add one additional section which will configure which exports will be available - more information you can find in Telerik Reporting Configuration Section help article.

If this information does not help you and your issue is different please elaborate.

Yes I'm using the ASP.NET report viewer. I do not use the export dd box anywhere in my code.
Do you have any other ideas?

Hello Jan,

It appears there is some miscommunication. From your post it is clear that you are using the ASP.NET report viewer and you're not using code to reference a rendering extension. We notice that you're setting the report declaratively in the aspx markup, however you should set the Report property programmatically as instructed in the Medium Trust Support help article. You can find sample code how to do that in the following help article: How to: Add report viewer to a web page.

All the best,

Hi Jan,

We have not been able to reproduce such a problem in our local tests and I have attached a sample project that functions correctly in our local tests with the latest official Q3 2012 SP1 release. We have tested this project with the 6.1.12.820 version as well and it works correctly as well. We would appreciate if you modify the project to exhibit the problem and attach the project in an official support ticket.
