Release 2025 Q3

Hi

Currently, when referencing an assembly from appsettings.json in telerikReporting:assemblyReferences  , the Object Data Source wizard in Telerik Web Reporting displays all namespaces from that assembly, even if only one class is marked with [DataObject]. This results in unnecessary namespace clutter and can confuse report designers, especially in large projects where only a single data object is intended for reporting. See screenshots below:


Please provide a way to control which namespaces and/or classes are visible in the Object Data Source wizard. Possible solutions could include:
•    Only displaying namespaces that contain [DataObject] classes (filtering namspaces with no elments to display)
•    Allowing explicit inclusion/exclusion of namespaces or classes via configuration (e.g., in appsettings.json).
•    Supporting an attribute (such as [Browsable(false)] or a new custom attribute) to hide specific classes or namespaces from the wizard UI.

Thank you for considering this improvement!

I have multiline text in a TextBox item that has its Style > TextAlign set to Center.

It is rendered as expected with the GDI+ graphics engine.

When I switch to the Skia graphics engine in the Standalone Designer .NET, though, some lines are not centered correctly in PDF rendering:

In Preview of the designer, with PNG and OpenXML export the text is shown as expected.

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.

I am using the HTML5 Report Viewer and have a multi-page report. When the report is previewed with the default pageMode setting, where pages are continuously scrollen into, the found search results are correctly highlighted.

However, if I use pageMode="SINGLE_PAGE" in the HTML5 Report Viewer initialization code, and I navigate to page 2 or further, the found results are not highlighted.

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.

I am using the HTML5-based Blazor report viewer, with the parameters area position set to "top":

<ReportViewer @ref="reportViewer1"
              ViewerId="rv1"
              ServiceUrl="/api/reports"
              ReportSource="@(new ReportSourceOptions 
                              { 
                                  Report = "SampleReport.trdp",
              })"
              Parameters="@(new ParametersOptions { Editors =
new EditorsOptions { MultiSelect = EditorType.ComboBox, SingleSelect = EditorType.ComboBox }
})"
              ScaleMode="@(ScaleMode.Specific)"
              Scale="1.0"
              ParametersAreaPosition="@(ParametersAreaPosition.Top)"
              EnableAccessibility="false"/> 

However, this causes the content of the parameters area to align incorrectly:

Some characters (for example, German Umlauts "Ü") render incorrectly when using a specific DPI setting and zoom level in the Standalone Report Designer during design/preview. 

I've found out this is due to the dots on the U are out of the text rect when the vertical align is set to top (which is the default). It appears they get cut off because they exceed the boundaries of the text box.

Our clients periodically send us MS Word files to use as a template for creating a customized report.  It would be convenient if there was a tool to efficiently import the text (including any formatting) into a report definition.  Once the report is created we would manually add a few parameters or data fields to the converted report in order to satisfy the client's requirements

When exporting an SVG image to PDF, polylines with stroke-dasharray are rendered incorrectly — the dash pattern is not applied.

Additionally, polylines with a stroke-width exhibit visual artifacts such as pixelation or inconsistent thickness.

Step by step instructions or code snippets how to reproduce the problem

  1. Save svg content (see below) as a file c:\test_svg_line_stroke.svg
  2. Create an empty report
  3. Add a picture box
  4. Select a value for the picture box - use file c:\test_svg_line_stroke.svg
  5. Go to preview - SVG is correct
  6. Click Export->Acrobat (PDF) file and export a PDF file
  7. Open PDF file to verify that the red line in a bottob does not have stroke-dasharray applied

If there's no black line with no stroke-dasharray - the red line in a bottom looks correct

<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xml="http://www.w3.org/XML/1998/namespace" width="500" height="400" viewBox="0, 0, 500, 400" preserveAspectRatio="xMinYMin" transform="scale(1)">
  <polyline points="100, 100 400, 100" stroke-width="7" stroke-dasharray="40 40" style="fill:none;stroke:#FF0000;" />
  <polyline points="100, 200 400, 200" stroke-width="5" style="fill:none;stroke:#000000;" />

Hi,

I'm working on a multiplatform project, using Telerik Reporting to generate PDF reports. The development is taking place on Windows.

The report is loaded programmatically (ReportPackager.Unpackage(...)), and the data is injected directly into the reports.

Some reports requires specific charts that are created as images and inserted into the PictureBox elements of the report before rendering. We are using SkiaSharp to generate these images, and I'm now trying to inject these images into the PictureBox elements.

For my first attempt, I have used the Gdi by first converting the SKImage to a System.Drawing.Image and it worked fine although it does not seem optimal.

Now I'm trying to write directly the SKImage to the PictureBox :

        public bool SetPictureBoxImage(string pictureBoxName, SKImage image)
        {
            PictureBox? pictureBox = (PictureBox?)_telerikReport.Items.Find(pictureBoxName, true).FirstOrDefault();
            if (pictureBox is null) return false;

            DrawingFactory.CurrentGraphicsEngine = GraphicsEngine.Skia;
            using var bitmap = SKBitmap.FromImage(image);
            IImage tlkImage = DrawingFactory.CreateImage(bitmap);
            pictureBox.Value = tlkImage;

            return true;
        }

However, when calling 'ReportProcessor.RenderReport(...)', a 'System.ExecutionEngineException' is thrown (no call stack, no additional details available).

I have tried to move the call 'DrawingFactory.CurrentGraphicsEngine = GraphicsEngine.Skia' before loading the report with no luck.

 

Is the 'Skia' rendering not available on Windows?

 

Please note that I cannot rely on the 'appsettings.json' file to configure the graphic engine.

I have tried to set the configuration programmatically through a custom implementation of 'Microsoft.Extensions.Configuration.IConfiguration' passed as an argument to 'ReportProcessor' constructors, but it had no effect. I have searched your code to find another way to set the configuration but it does not seem possible as everything is static and internal.

 

Kind regards

Currently, when you press the Generate button, you can't see in the UI that something is actually happening. After some time, the response appears. This can be confusing for the end user.

Hi Telerik team

I'd like to implement customer specific colors based on a report variable or database field.
Currently it looks like the color properties only give us a color picker but does not support using an expression, is this correct?

As for context, I do not know the color in advance and it is used at 100+ different objects.

Same problem with conditional formats

Please let me know how to choose colors based on expressions.
If this is not possible yet, I'd like to request it as a new featur.

Best regards,
