Add preconfigured data sources and hide

Hi,

My mentor wants me to set pre configured data sources on every report so the users who are manipulating it don't need to add the same data sources everytime.

Furthermore, I would need to disable the data sources buttons as well but I already found workarounds for it here. On the other hand I am wondering if there is a better solution since at the bottom of the post there is a text which says:

Note that experienced users can look through the raw HTML and find the hidden DIV tag. But until the Web Designer gets the added features of customizing the UI, this is the closest solution.

Thanks a lot in advance.

UPDATE: actual post title:

Add preconfigured data sources and hide data source buttons

sorry for inconvenience

Telerik Reporting PDF export fails when hosted on Docker

Hi,

I am using Telerik.Reporting library (15.2.21.1110) in Blazor Server application.
The report was created in standalone Report designer (.trdp).
I can display that report in the Blazor ReportViewer component.
When running the web app on Windows I can export to PDF, DOCX via the ReportViewer and also without the REST service using Telerik.Reporting.Processing.ReportProcessor.RenderReport().

The problem occurs when building the application as Docker RedHat based image.
In that case the DOCX works but the PDF fails in both scenarios (REST report service and ReportProcessor) throwing eventually System.OperationCanceledException.
Dockerfile instructs to use RedHat UBI8 base image and install GDI+ Win library replacement for Unix systems (glibc-devel, libicu, libX11-devel, libgdiplus).

Do you have any suggestions what could be wrong?

Log4J vulnerability

In the aftermath of the Log4J security breach, we need to be sure that all vulnerable components are patched.

I guess there are no Java components and hence not Log4J involved in any of Telerik's components, but can this please be confirmed?

Parameterized report in Angular .Net Core with PostgreSQL database issue

I am facing the issue with parameterized report with PostgreSQL database in Angular .NET Core application.
I have configured everything as per the documentation. I tried lots to resolve this issue at my end but parameterized report not loading details when passing params from angular, If I used to designer preview it is fine. For testing purpose, I changed the database to SQL Server and same code and configuration works. I needs working solution for this with PostgreSQL database for parameterized reports. If anyone worked with parameterized report with PostgreSQL database in Angular .NET Core application. Please suggest solution for it.

Displaying jsignature in Report PDF

I've used jsignature (https://willowsystems.github.io/jSignature/) in my ASP.Net Core app to capture a signature made in the app.

It is stored in the SQL database in a varchar(2000) field. I can display it back in the app afterwards.

How do I get it to display in the Report PDF. If I include the field (from the datasource), it shows as follows when previewed in the standalone report designer (R3 2021)

I've read elsewhere in Teleirk forums that it can be bound to a picture box but I don't see how to bind the picture box to a report field.

I don't need to capture the signature in the report pdf, just include it.

SkipBlankPages set to false but report still displays nothing at all when dataset is empty

My report has a header, footer, and 3 group sections. When I choose parameter values that result in data to display the report has everything as it should be. When I pick parameter values that result in no data rows returned to the report it shows nothing whatsoever; no headers/trailers/labels of any kind, even with SkipBlankPages set to false.

For what it's worth the debug window is displaying an error message both when the report is successful with data and when it is not. Maybe that error is affecting the report's behavior only when it has no data to display? Here's the text of the debug messages. Is there anything else I can provide that would be useful for this issue?

The local server has the latest 5.0 version of ASP.NET and the latest 3.1 version of .NET Core installed. Would you have any idea what may be causing this?
