Hi,
After getting the
"Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."
error about Telerik Reporting, I have applied the steps described in the following thread(Medium Trust issue).

http://www.telerik.com/community/forums/reporting/telerik-reporting/loaderexception-exporting-pdf-report-from-web-page.aspx

After that I started to get this error message about OraclePermission.

"Request for the permission of type 'System.Data.OracleClient.OraclePermission, System.Data.OracleClient, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."

I've tried to setup trust level in web.config file as in the example but couldn't solve the problem.
<securityPolicy>
<trustLevel name="Custom" policyFile="web_customtrust.config" />
</securityPolicy>
<trust level="Custom" originUrl="" />

Would you give me any walkthrough for this issue?

Thanks in advance.

Hi mesut,

You are receiving this error message because you do not have permissions to connect to an Oracle database via the System.Data.OracleClient ADO.NET data provider. To resolve this problem you need to add the following lines to your "web_customtrust.config" file:
 
<configuration>
  <mscorlib>
    <security>
      <policy>
        <PolicyLevel version="1">
          <SecurityClasses>
            <SecurityClass Name="OraclePermission" Description="System.Data.OracleClient.OraclePermission, System.Data.OracleClient, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />

and
 
<configuration>
  <mscorlib>
    <security>
      <policy>
        <PolicyLevel version="1">
          <NamedPermissionSets>
            <PermissionSet class="NamedPermissionSet" version="1" Name="ASP.Net">
              <IPermission class="OraclePermission" version="1" Unrestricted="true"/>

A bit off topic, please ask the person who has purchased our controls in your company to add you as a License Developer to the purchase. This will give you full access to the products your company has purchased, to our downloads section, and to our support ticketing system. Additionally, all your questions will be reviewed according to the license you have. More information on License Developers you can find here: www.telerik.com/account/faqs.aspx.
