Dear support team and community ,

We are using Progress Telerik Report Server R3 2022 SP1 (8.2.22.1109) and want to configure it to use reports with custom functions. We created a library in the form of a .dll file that contains the function we call. All of that was successfully done using Standalone Report Designer, we have imported the library and we are successfully accessing it using Object Data Source.
However, when we wanted to do it on the Telerik Report Server running on the IIS server, we were unable to access the custom function found in the library and got an error on the Telerik Report Server web application.
We followed the instructions from the documentation found at this link: 

After we copied the assembly to the bin folder and registered the same assembly in the corresponding application configuration file ([Telerik Report Server installation folder]\Telerik.ReportServer.Web\TelerikReporting.config), we got an error with this text. 

"Unable to cast object of type 'System.Configuration.DefaultSection' to type 'Telerik.Reporting.Configuration.ReportingConfigurationSection'."

I am sending a picture and an attachment.

Could you please help us in solving this problem.

Hello,

I saw this documentation to read zip files with a password.

https://docs.telerik.com/devtools/document-processing/knowledge-base/zip-unzip-multiple-files-password

But is there a way to check if I need a password or to check if the Zip file has a password protection?

I need to translate the SQL query to a relational algebra expression. 

SELECT P.Name 
FROM Players P, Games G
WHERE P.Id =  G.PlayerId
    AND P.Game = 'Football' AND G.Season ='2019'

Hello!

I would like to know how to delete the Telerik user account I had to create in order to download a trial version a while ago. Unfortunately, I couldn't find any hints on how to do this. Maybe someone here can help me to remove the account?

Thanks in advance!

We are in process of trying out Telerik UI for ASP.NET AJAX  PdfViewer and have observed that the demo page https://demos.telerik.com/aspnet-ajax/pdfviewer/overview/defaultcs.aspx is not correctly rendering in few machines .

Here is the output that we are seeing.

Is there a system setting that needs to be added to correct this issue?

Thanks.
