Scheduled for 2025 Q3

With the 2025 Q2 release, the 3-parameter AddTelerikReporting static method was replaced with a 4-parameter method containing an additional argument for the optional AIClientFactory method of the REST Service.

The original method should be returned to avoid breaking projects that do not implement an AIClientFactory.

Indeed, the Telerik.Reporting.WebServiceDataSource depends on the following packages, as seen in its nuspec file:
<dependencies>
  <group targetFramework=".NETFramework4.6.2">
    <dependency id="Newtonsoft.Json" version="13.0.1" />
    <dependency id="Telerik.Reporting" version="[19.0.25.313]" />
    <dependency id="Microsoft.Net.Http" version="2.2.29" />
  </group>
  <group targetFramework=".NETStandard2.0">
    <dependency id="Newtonsoft.Json" version="13.0.1" />
    <dependency id="Telerik.Reporting" version="[19.0.25.313]" />
  </group>
</dependencies>

The package "Microsoft.Net.Http" is with the latest available version and depends on:

Microsoft.Bcl (>= 1.1.10)
Microsoft.Bcl.Build (>= 1.0.14)

The package "Microsoft.Bcl" is indeed deprecated.

When exporting to XLSX, all cells have a white background color even though all my report items have a transparent background. In this scenario, I want to see Excel's gridlines so the cells should be transparent, just like they are in the XLS export.

Is it possible to get descriptive information exposed for the ReportsControllerBase swagger endpoints? do they exist?

Notice how the About and files endpoints have information next to them:

Like-wise how the files endpoint has descriptive parameters:

In the Telerik Reporting Designer there are already quite a few Chart Diagrams included but the one that is missing is a Sankey Diagram. This is already integrated in the Charts in KendoReact for example and I would like to request to also add this in Telerik Reporting because I think it would be a great addition and also we would for sure need this.

Thanks,

Regards,

Bernd

In the Report Preview of the Web Report Designer, there does not seem to be a way to provide a null value to a nullable data source parameter.

For example, I have a nullable DateTime parameter. After the data source is configured the data source parameter DataType is set to String, it did not resolve to nullable DateTime. Even after I change the data source parameter to DataType of DateTime it cannot accept a null value from a DateTime report parameter, it seems to be interpreted as a string instead of null.

In the Standalone Report Designer there is no problem having a DateTime report parameter passing null to a nullable DateTime data source parameter; after reconfiguring the data source in the Standalone Report Designer the DataType for the data source parameter is <DataType>System.Nullable`1[System.DateTime]</DataType> instead of <DataType>System.DateTime</DataType> as from the Web Report Designer.

The PDF with enabled Accessibility looks fine in the Adobe PDF reader.

However, when I check it with the PAC tool, it shows in the logical structure the Detail section first, then the Page Header, and then the Page Footer.

Release 2025 Q3

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 am encountering issues when using the objectDataSource wizard in the Web Report Designer that are not issues with the Standalone Report Designer. The Telerik Reporting version is 19.0.25.313. I created an object data source class that returns "Widgets" in a DataSet and a report "Demonstrate objectDataSource issues in Web Report Designer.trdx" to demonstrate the issues.

1. 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.

2. For a data member that returns a DataSet result, a table row has to be returned for the design time feature to generate a data schema. In the Standalone Report Designer a returned row is not necessary, all that is required is a returned DataSet with a Table with Columns setup. It would be easier when using Web Report Designer to not require data returned to establish the data source data schema. In the WidgetDataSource a fake row is returned for the sake of having the data schema generated.

3. In the Web Report Designer 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. 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 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.").

4. In the Report Previewer for the Web Report Designer there does not seem to be a way to provide a null value to a nullable data source parameter. For the GetWidgets member the FromEffectiveDate parameter is a nullable DateTime. After the data source is configured the data source parameter DataType is set to String, it did not resolve to nullable DateTime. Even after I change the data source FromEffectiveDate parameter to DataType of DateTime it cannot accept a null value from a DateTime report parameter, it seems to be interpreted as string instead of null. In the Standalone Report Designer there is no problem having a DateTime report parameter passing null to a nullable DateTime data source parameter; after reconfiguring the data source in the Standalone Report Designer the DataType for the data source parameter is <DataType>System.Nullable`1[System.DateTime]</DataType> instead of <DataType>System.DateTime</DataType> as from the Web Report Designer.

5. This is not a specific objectDataSource wizard issue but rather a general issue in the Web Report Designer. 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 message (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.

Hi,

In Desktop Designer, I create a very simple Report with :

  • a JSON datasource mapped to the report
  • a Table with two colunms

I want to duplicate this table, so I select it and do a copy. After that, I select the detailSection and do a paste. The pasted table, in the Report Explorer look fine, but in the designer view it is not the case. And if I compare the TRDX files, an entire section is missing (the <Cells> section).

Attached files :

  • Multi-zone.trdx : Before copy/paste
  • Multi-zone-2.trdx : After copy/paste
  • Screenshot.png : screenshot of the Designer where you can see the two tables and the Report Explorer

Thank you

PS: In additional informations, I specify ASP.NET MVC as Project Type, but it is not relevant.

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,

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.
