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.
If I use an HTML5-based Report Viewer with the default CONTINUOUS_SCROLL page mode and I start scrolling to the next page, the Get Document Page request is made multiple times for the same page.
If I move to the next page via the toolbar buttons or if I use the SINGLE_PAGE page mode, then problem is not reproduced.
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!
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:
CSharp.Net8.Html5IntegrationDemo Error: 0 : System.IndexOutOfRangeException: Index was outside the bounds of the array.

Watermark Images with higher than the report rendering DPI are displayed clipped in PPTX rendering.
In PDF, preview of the designers and DOCX the same watermark is shown as expected.
If the DPI of the image is 96 as the default Windows machine DPI used for rendering, the Watermark is displayed correctly also in PPTX.
To reproduce, use online web designer demos with Employee Sales Summary.trdx report.
Check the video https://go.screenpal.com/watch/cTfDlNnj4I1.
- The main report opened in the designer has a Navigate to Report action.
- Preview the report and trigger the action to open the second report.
- Now, click on Design to go back to design time.
Expected: opens the main report
Observed: In design you see the second report
Additionally, the URL to the second report is absolute rather than relative path - the issue logged in Full system-path being used by REST Service as reference when linked by a 'Navigate To Report' action
2. Toolbar Button Properties: Along with this, since IReportViewerTool exposes the Icon and CommandName, request it also expose an Enabled property. At a bare minimum, it would be helpful if, while rendering, all but the 'Stop Rendering' (Cancel) and Pager buttons are disabled by default or by setting a new viewer property.
Currently we must use JSInterop to accomplish these things.
The reason we are managing these things in the first place is because we are using Custom Parameter Editors (CPEs). When a long-running report is in the process of rendering, and a user changes a parameter and re-requests the report (either via our 'Retrieve' button or a viewer toolbar button), an unhandled exception occurs in _content/Telerik.ReportViewer.BlazorNative/js/reporting-blazor-viewer.js. So we make use of the OnRenderingBegin and OnRenderingEnd events to disable/enable the CPEs. The problem arises when the 'Stop Rendering' (Cancel) button is clicked. Since we cannot detect the button click, our CPEs remain disabled.
In Telerik Reporting versions before 18.1.24.514, I could change the order of items in a section by dragging an item up or down in the Report Explorer list.
If I try that now, nothing seems to happen on the screen. Dragging does not appear to change the position of an item in Report Explorer; the item appears to be fixed in place. However, if I close the report and reopen it, the position of the item may have changed.
The same happens if I use Send To Back/Brink to Front on an item. The new item position is not updated in the Report Explorer.
Password-protected PDF documents generated with Telerik Reporting have blank pages when opened with an iPhone.
After updating the Reporting version to v18, some error messages display the <br /> HTML element as text in the HTML5 Report Viewer. The issue was not present in v17.
I have created an abstract class in my report library that inherits from Telerik.Reporting.Report. When I try to load the project's assembly in the Standalone Report Designer to import those reports as TRDP, an exception is thrown while the application tries to load the assembly that there are report types that do not have a parameterless constructor.
To resolve the issue, I had to remove the 'abstract' modifier. However, that should not be necessary. The wizard should ignore abstract classes or at the very least, let me import the other report types while displaying a message that there are report types with parameterless constructors.
When trying to open reports from an assembly in the Standalone Report Designer so that they can be imported, if there are types that inherit from Telerik.Reporting.Report that do not have a parameterless constructor, this will cause an exception as it is required for the report types to have such a constructor, otherwise, the wizard cannot import them into TRDP.
In this scenario, the report types that do not have a parameterless constructor should be written to the trace or in the exception message dialog so that the user can see which are the problematic types and correct them.
In the attached report, all items in the detail section have Docking set to Top.
In the Interactive view of the report designer, the report looks fine.
In PrintPreview mode though, some items overlap.
There is an issue in .NET 9 when using a mounted network drive. When resolving reports, I get the following exception:
The issue seems to be related to a regression introduced in .NET 9:
- For a network drive, System.Windows.Forms.Application.StartupPath returns a path with \?UNC\ prefix
- Work with 'Mounted Network Drive' in .NET 9.0
Consider finding a way to work around this issue.
I pass the value of an Integer Report Parameter as '11000000000000003' from the viewer's setup. In the viewer though it appears as 11000000000000004. The wrong value 11000000000000004 is seen also in the 'parameters' request passed from the viewer to the service.
The issue is reproducible in the HTML5 Report Viewers and in the Blazor Native Report Viewer.
Currently, TIF images cannot be selected as pictureBox values from the file dialog of the Standalone Report Designer. However, the documentation states that it is a supported image format:
Sometimes I need to be able to allow the users to choose not only the date but the time as well when displaying DateTime report parameters in my reports. There is no out-of-the-box functionality to achieve this and I am forced to implement custom parameter editors - Creating and Using Custom Parameter Editors in HTML5 ReportViewer - Telerik Reporting.
I should be able to set whether a DatePicker or DateTimePicker widget should be used for DateTime parameters from the report viewer's initialization options, such as how I can change the editor for single/multi-value parameters in the HTML5 report viewers - HTML5 Report Viewer Options Overview - Telerik Reporting.
This behavior is observed only on Azure environment and it is working as expected on local machine.
It seems the Character ID (CID) is mapped to a wrong position visible in the inserted text and in the CMAP table and this leads to an incorrect glyph loading.
