If you add transparency to a Graph line, for example, the Y-axis, with an alpha value: '150, 255, 255, 192', it is respected in the Standalone Report Designer, where the rendering format is Image.

In the Web Report Designer and in the HTML5 Report Viewer preview, the alpha value is ignored, and the color is rendered as '255, 255, 192', which removes the transparency.

In MSSQL, you may use syntax like 'StoredProcedureName;1' to indicate stored procedure versioning, but it is not yet supported by Telerik Reporting.

I use such syntax and need to remove the version to make this work in Telerik Reporting.

It would be great if you also added support for versioning in MSSQL stored procedures.

The Table of Contents(TOC) section is displayed at the bottom of the document map, despite appearing at the beginning of the rendered report itself. This can be confusing for the end-user.

Consider adding support for a ToC in the XLSX rendering format. Depending on the `SplitWorksheetOnPageBreak` device info setting, I expect the hyperlinks to either lead to a section within the same worksheet or to a different worksheet.

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.

I am working with a static report (not using tables or groups), and I need to set the Level / TOC Level under the Interactivity section for an HTMLTextBox.
However, in my report, the Interactivity options do not show any property for Level. I am only seeing basic properties like Action, BookmarkId, DocumentMapText, TocText, etc.
The Level field is completely missing.

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 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.

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.

In Chromium browsers such as Edge and Chrome, if I have set PDF files to always be downloaded from the browset content settings, and I click on the print button in the toolbar, the print dialog is never displayed, nor is the PDF downloaded.
