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.

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.

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?

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.

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.

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.

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, the GetDesignerResource endpoint of the Web Report Designer service is case-insensitive, which can lead to issues if the URL is made lowercase at some point, such as by a URL rewrite rule, or similar scenarios.

For example, the following reference to the Web Report Designer script will load return the file:

<script src="api/reportdesigner/designerresources/js/webReportDesigner"></script>

But if lowercase is used, for example, like this:

<script src="api/reportdesigner/designerresources/js/webreportdesigner"></script>

The request will return a 404(Not Found) response.

Using Blazor native reporting component.  Our underlying email sending service requires that Subject is not blank, however the UI does not validate the Subject field.

Need to be able to validate that Subject is not blank when user attempts to submit email form.

We are experiencing issues with Telerik Reporting related to RTL text (culture 'ar-JO') rendering, as outlined below:

  • Text wrapping is not working correctly within the HTML5 Report Viewer. The text seems to overflow the TextBox.
  • When exporting to PDF, the text exceeds its boundaries, does not wrap as expected, and in some cases is cut off.

If a user changes the page number in the input box and then clicks the refresh button, an error is thrown, and the report styles break.
This also triggers multiple requests without an instance ID and document ID, resulting in 404 Not Found responses.

I'm getting an error in Telerik Report Designer (Data Explorer): "Member x on type String not found"

The version is: 19.3.25.1119

Steps to Reproduce:

  • Open SRD.NET.
  • Configure the Assembly References through the SRD.NET UI to include a DLL.
  • Open an existing report file.
  • Observation: The Data Explorer tool window is populated correctly, showing all fields and methods as expected.
  • Close Telerik Report Designer.
  • Re-open Telerik Report Designer.
  • Verify that the Assembly References are still correctly configured (they are).
  • Open the same report file.
  • The Data Explorer is not populated. Instead, it throws an error:

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.

I had an issue with watermarks being present in the generated PDF despite the license validation passing. In the trace log, I was seeing this:

The issue turned out to be due to caching, but the output puzzled me while I was debugging this. Turned out `ForceLicenseWatermark` is always true (the misleading part), but only has an effect when the license validation fails.

I display a report with a few HtmlTextBox items in my WPF application through the WPF Report Viewer. I load the fonts used in the report as private fonts, since my application's users may not have some of them installed on their machines.

This results in the text being cut off at the end despite there being available space in the item. On the other hand, the issue is not present when the font is resolved normally.
