The data member list in "Choose a data member" (step 2) of the objectDataSource wizard in the Web Report Designer does not appear to be in alphabetical order as it is in the Standalone Report Designer.

When there are many data members it is hard to pick the one you want when not ordered alphabetically.

In the Web Report Designer's objectDataSource wizard, once the "Preview data source results" (step 4) are ready and the Finish button is clicked, there is another call to the data source member but instead of using the Design-Time Values for the member, the values in the Value column appear to be used.

For example, If report parameters are already assigned to the data source parameters the string of the Value (e.g. "= Parameters.StartDate.Value") is used instead of the actual report parameter value.  I think the data member call to generate the data schema should be the Design-Time Values again. In order to get the data schema generated I had to use the same values for Value column as in the Design-Time Values value.

After the data source parameters are assigned to report parameters then it breaks the generation of the data schema later when the report is opened again in the Web Report Designer and there is an error (e.g. Error An error occurred while loading the data schema for "Widgets". ("Message"."String was not recognized as a valid DateTime.").

 I cannot create a Report Parameter with the same name as a data source parameter or CSV data source field. Trying to do so results in an error messagе

(Error Could not change property 'Name'. Name 'FromEffectiveDate' already exists).

This issue can be demonstrated in the Web Report Designer Demo page: create a parameter for the yearDataSource data source, try to create a report parameter with the same name to get the error.

Using report parameter names that are also data source parameter names works fine in the Standalone Report Designer.

I have the chance to use a 27", 5120 x 2880 monitor, with text on Windows set to 200%.

The problem with Telerik Report Designer is that the icons in the report designer are very small and barely usable:

- Panel icon to move it.
- Table icon to move it.
- The open / close icons in the Report Explorer.

Also the zoom indicator at the bottom left of the screen, where the text part is too small to display the current zoom.

Steps To Reproduce:

1. Install Reporting.
2. Go to \Tools folder.
3. Start DatabaseCacheConfigurator.exe
4. Leave the first combobox to 'Create engine viewers/cache database'
5. Paste a valid connection string in the textbox below, e.g. Data Source=.\sqlexpress;Initial Catalog=AdventureWorks;Integrated Security=True
6. Click on Create Schema or Clear Cache Data.

Expected behavior: The function is executed

Actual behavior: A message saying "Operation could destabilize the runtime." is shown.

I have denied the permission to use the Asset Manager in the configuration of the service of the Web Report Designer. This is generally respected and I do not see the option to open the asset manager from the main menu but when I try to set an image to a PictureBox item, I still see the option to add it from the assets and the button is also clickable.

With that being said, the permission is respected on the server and I get an error about not having permission to use the Asset Manager when I click on the button. Still, it will be better if the button is removed from the UI altogether when I have disabled the assets.

The HTML5 Report Viewer uses inline templates which may require enabling the unsafe-eval CSP policy.

The viewer should migrate to using CSP templates as shown in Getting Started with Content Security Policy (CSP) Templates - Kendo UI Templates - Kendo UI for jQuery.

When there is a combination of Arabic and English text in any control and if the font family is set to "Calibri", exporting to PDF results in the following error in the stack trace:

If we change the font family to "Arial" the report is exported to PDF correctly.

When using a date parameter with AutoRefresh set to True in the Standalone Report Designer, selecting a new value from the date picker does not automatically refresh the report viewer to show the updated report. To make the new value take effect, you need to move the focus away from the date picker.

When upgrading my .NET Framework project with the Upgrade Wizard, the Telerik.Reporting.OpenXmlRendering assemblies, including the newer 2.7.2 and 3.0.1 ones, are not upgraded

All assembly references except Telerik.Reporting.OpenXmlRendering ones are updated. The upgrade wizard finishes without errors.

This is very annoying as I have to replace them manually,

Hello Telerik Team,

I would like to suggest a feature enhancement for the Web Report Designer that would allow dynamic configuration of design-time parameter values during initialization.

Currently, design-time values for report parameters are embedded within the report definition and can only be set manually using the Web Report Designer interface. While runtime parameter values work perfectly and can be passed dynamically through code, not being able to dynamically set design-time values causes significant limitations—especially during the report design process.

My Use Case:

In my application, I load data from a dynamic web service endpoint, and the service domain needs to be set at runtime. While this works fine during preview in my ASP.NET MVC project (where I pass the URL dynamically using report parameters), I run into issues when designing reports:

• During design time, the URL has to be manually entered into every Web Service Data Source just to fetch the model fields and avoid errors.

• If the domain name changes (e.g., due to staging/production environments), I must manually update the domain in every report and each Web Service Data Source, which is both time-consuming and inefficient.

• This becomes even more tedious in large projects with many reports and data sources.

So, my question is: Is it mandatory to pass design-time values (like the service URL) manually just for design-time purposes? If not, it would be incredibly helpful to have a way to supply these values dynamically during the Web Report Designer initialization, perhaps via a configuration option or external context.

Petar from the Telerik team mentioned that this would indeed be a valuable feature and encouraged me to submit this suggestion. You can view our discussion here: 🔗 Dynamic Web Service Domain Configuration in Telerik Report Designer Server

This capability would make designing reports much smoother and far more maintainable, especially for applications that rely on dynamic, environment-specific configurations.

Thank you for considering this request, and I appreciate your continued support and guidance.

Screenshots are also attached for quick reference, though they are already available in the forum link above.

Best regards,
Prabesh

When I export my report in Excel with the Standalone Report Designer for .NET,  the GDI engine produces the expected result, whereas with the Skia graphics engine, the Graph in the report is rendered with a bold font, although I use a regular/normal font.

Hi Team,

I would like to request an HTML5 ASP.NET Core Report Viewer similar to the MVC version with wrappers.  It would be great to be able to utilize Razor Syntax for developing instead of pure jQuery.

Thank you!

I have a .NET Framework 4.7.2 ASP.NET MVC project.

I am currently on Telerik.Reporting 19.0.25.211. I also have Telerik.Licensing package 1.4.10 installed on the project.

After upgrading my project to Telerik.Reporting 19.0.25.313, without touching the licensing package, in my .csproj file I'm seeing Telerik.Licensing.Runtime reference is set to 1.4.6.0, although the nuget package manager says that I have 1.4.10 installed.

In the project References also appeared a reference to the old Telerik.Licensing version after the update.

Currently, when using External Stylesheets in the reports, the engine tries to first load the stylesheet as an embedded resource of the assembly. If it fails to load it from the assembly, a message is written to the trace along the lines of:

ESS: Attempt to load ExternalStyleSheet from EmbeddedResource from assembly Telerik.Reporting, Version=19.0.25.211 with resource name styles.xml is unsuccessful.

After this, the engine will try other ways to resolve the stylesheet such as from URI and if it succeeds, the report will render as expected.

This can create confusion because looking at the trace, one might think that there were errors with the rendering of the report because the stylesheet did not load but it was actually successfully loaded with one of the other approaches.

It would be better to write the errors to the trace only if the stylesheet does not load after all attempts.

We have successfully downloaded and installed Google Open Sans fonts (from the URL:  https://fonts.google.com/specimen/Open%20Sans#:~:text=Open%20Sans%20is%20a%20humanist%20sans%20serif) to a Linux Ubuntu-based Docker container using the following Dockerfile script to install the dependencies and the fonts:

RUN apt-get update && apt-get install -y libfreetype6 libfontconfig1 fontconfig unzip

#Google Fonts
RUN mkdir -p /usr/share/fonts/truetype/googlefonts && cd /usr/share/fonts/truetype/googlefonts
COPY ["Open_Sans.zip", "/usr/share/fonts/truetype/googlefonts"]
RUN unzip -d /usr/share/fonts/truetype/googlefonts /usr/share/fonts/truetype/googlefonts/Open_Sans.zip
RUN rm -f Open_Sans.zip
RUN ls -al /usr/share/fonts/truetype/googlefonts
RUN fc-cache -fv
RUN fc-match OpenSans

Open_Sans.zip file should be in the solution folder when running the Docker from Visual Studio.

The fonts are displayed as expected when previewing in the browser. When exporting to PDF though, the Reporting engine throws the following exception when Open Sans font is used:
