I have a crosstab with a dynamic number of columns (time periods) that can exceed 15-20 columns. When exporting the report to PDF in A4 landscape format, excess columns are truncated and never printed on additional horizontal pages.

The issue is related to the Crosstab property 'RowHeadersPrintOnEveryPage'. When set to True, it places additional row headers on each page when using physical pagination. I suspect these additional headers are not taken into account when calculating the necessary page area, hence the final part of the Crosstab is skipped.

Hello Team Support,

I work with the ReportViewer in WPF. I modified the description of some format in my App.config.

When I export my report, if the description is too long, it does not fit the message window anymore.

Here is a screenshot of my issue:

Thank you in advance.

Best regards,

Jonas

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.

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);

My table may contain text consisting only of repeating '1', i.e., "11111111111111111111111111111111". When this content cannot fit inside a single line, the Table generates a second row; however, part of the content spills out to the next Table column.

With other repeating characters like 'I', 'l', '2', and 't', the issue didn't reproduce. When the line contained other characters, the problem didn't occur as well.

I have an image set to the checkbox through the CheckedImage property. When I export the report to Excel using the Skia graphics engine, the image is not present at all, or cut off.

The same issue is not present in the GDI engine or with the PictureBox item.

I have a simple report with two TextBoxes in the detail section. In one of them, the content wraps as it doesn't fit, and in the other, it doesn't.

When I export to Excel (XLSX), under each detail section, there is an empty row.

When I left only the TextBox with the wrapping content, there were no empty rows in the Excel file.

I load multiple variants of the Segoe UI font as private fonts in my application:

			<!-- Segoe UI -->
			<add fontFamily="Segoe UI" path="Fonts\SegoeUI\segoeui.ttf" fontStyle="Regular" />
			<add fontFamily="Segoe UI" path="Fonts\SegoeUI\seguisb.ttf" fontStyle="Semibold" />

This leads to issues, as there is no "Semibold" option in the System.Drawing.FontStyle enum.

The workaround that can be used to avoid this problem is to use unique font family names. For example

			<add fontFamily="Segoe UI" path="Fonts\SegoeUI\segoeui.ttf"  />
			<add fontFamily="Segoe UI Semibold" path="Fonts\SegoeUI\seguisb.ttf"  />

I have a report where I have placed a bunch of textbox items at the bottom of the page header that I use as headers for my data that I display in the detail section.

When I run the report in a Docker Linux container, where the Skia graphics engine is used, the items at the bottom edge disappear when rendering the report in the web report viewer(HTML5 Interactive) rendering.

The issue does not occur when I render the report with the "PRINT_PREVIEW" viewMode setting or when I use GDI+..

I have noticed that the performance of exporting reports has gotten worse in recent releases. After investigating, I found out that this is likely caused by the sheer size of the code in my projects.

To prove this, I created a simple application that renders a report to PDF programmatically. Then, I created 10 000+ dummy classes in the same project, and tried rendering the report again. The performance was noticeably impacted by this change.

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'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:

Please note the spelling error in the k-notificaiton-error class name. Should be k-notification-error:

<div class="trv-parameter-error k-notification k-notificaiton-error" style="">
                <span class="k-notification-status k-icon k-i-x-outline"></span>
                <span class="trv-parameter-error-message k-notification-content">Parameter value cannot be empty.</span>
            </div>

Because of this, error messages are rendered with incorrect color (should be red):
