Description
Even though there is no map wizard for the WRD, it is possible to create a map item and try to set it. However, it is not possible to select an ESRI Shapefile for the spatial data or inspect the already existing one in the report:

Steps To Reproduce

  1. Use the PopulationDensity report
  2. Open the ShapeMapSeries:

  1. The Source type can't be configured:

Expected behavior
Even with no map wizard in the WRD, the map item should be created from scratch, and all properties should be editable.

Actual behavior
The Source Type doesn't show any option for selecting shape files.

Hi, our project uses the Telerik Report Service with Asp .NET Core with Keycloak as Session Provider, every time the user tries to use an Report, after some time, he gets  Unauthorized error.

To solve this I've implemented a way to specify the login promise (that is called before each request) when starting the HTML5 Report Viewer.

 

What if it becomes an native feature?

The attached report generates different PDF documents when rendered by the Standalone Designer and REST Service, both targeting the .NET Framework 4.6.2:

  • The PDFs have different sizes
  • When using the 'Read out loud' functionality of the Adobe Reader, the items are read in a different order. The order in the PDF generated by the designer is correct, and the one in the service-generated PDF is wrong.

I have a report with a "Navigate To Report" action, which, when triggered, sends the absolute URI to the IReportSourceResolver.Resolve method.

The provided URI should instead be only the relative URI that I have set on the action.

Currently, when configuring an ObjectDataSource with an async method that returns a `Task<T>`, the ObjectDataSource wizard displays `Task` members (such as `AsyncState`, `CreationOptions`, `IsCanceled`, etc.) instead of the actual data properties. Consider adding support for such async methods.

I have a report with an HtmlTextBox item, which contains an ordered list(<ol>). When I export this report to PDF, and inspect the logical tree of the document with a tool like the PDF Accessibility Checker, I can see that the span with the text is inserted above the number.

As a result, when I read the document with a screen-reading tool like Adobe's "Read Out Loud" feature or NVDA, the text is read before the current number in the list, which I find unexpected.

Currently, Telerik Reporting has a dependency on Microsoft.Data.SqlClient version="5.2.2".

This version may cause build failure when restoring packages due to locked package files.

See the following dotnet issue for more information about the problem: dotnet/SqlClient#2464

My report has a Text Watermark as part of the PageSettings, and is configured for Accessibility. The report contains a Page Header and Page Footer. In the Page Footer, there are two TextBoxes.

When I generate an accessible PDF with Telerik Reporting and use the Adobe Reader > Read Out Loud functionality, it doesn't read the content of the second TextBox in the Page Footer.

Release 19.3.26.121

I have a Website ASP.NET project, and I am trying to implement the Reporting REST Service in it. To do that, I have tried to install the Telerik.Reporting.Services.WebApi package to my solution. However, when I attempt that, I get the following error:

The package 'Telerik.Reporting.Services.WebApi' tried to add a framework reference to 'System.Web.Http' which was not found in the GAC. This is possibly a bug in the package. Please contact the package owners for assistance.
Cannot find assembly 'System.Web.Http'.

It seems that the package requires that the System.Web.Http.dll assembly is available in the GAC, otherwise, the package cannot be installed.

The workaround to be able to install the package is to manually install the assembly to the GAC, or paste it in C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.8.

When my application is hosted on Windows, Arabic date values appear reversed in the day part during PDF export with the Skia graphics engine. For example, 2025/01/01 is displayed as /01/10 when Arabic digits are used.

With the GDI graphics engine, the Date values are rendered as expected.

As of now the Reporting team provides only part of the source code - mostly the code that targets .NET Framework 4.6.2.

Please expose more of the code to your customers, like Telerik Reporting engine for .NET 6+ and corresponding REST WebAPI.

I use an approved government font for the reports. I have specified it in the `privateFonts` option of the report engine configuration. However, on Linux, it is not picked up during rendering. In FontForge, the font shows the following warning:

On Windows, it causes no issues.

I have 2 Date parameters on my report. The "Start Date" parameter defaults to today, and the "End Date" defaults to the "Start Date" + 1 Year.

This works fine in the Report Designer, e.g., when the Start Date is changed in preview mode, the End Date value is recalculated.

However, this behavior does not work in the Blazor Native Report Viewer.  When the page first renders, the two dates are shown correctly, but if the Start Date is changed, the End Date is not recalculated.

My application uses RadDocking. When the WPF Report Viewer is hosted in RadDocking, some Graph labels appear cut.

The problem is related to the property UseLayoutRounding="True" in the RadDocking.

The workaround is to use the following setting:

RadPane pane = new RadDocumentPane();
pane.UseLayoutRounding = false;
pane.Header = "Report";
pane.Content = reportViewer;
DocumentPaneGroup.AddItem(pane, Telerik.Windows.Controls.Docking.DockPosition.Center);

As soon as I reference a .NET 10 assembly containing models, there is a null reference exception that does not appear in EventViewer or Fusion logging at the opening of the Standalone Report Designer for .NET.

Here is a link to a muted video demonstrating how adding assembly references using the UI successfully adds the custom assembly to the designer, as well as the bug when removing the assembly version.
