Consider adding support for the `start` attribute of the `ol` element in HtmlTextBox. This would allow us to change the start counting:

The HTML5 Report Viewer uses inline templates which may require enabling the unsafe-eval CSP policy.

The viewer should migrate to using CSP templates as shown in Getting Started with Content Security Policy (CSP) Templates - Kendo UI Templates - Kendo UI for jQuery.

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

I am using the AI-powered insights functionality of Telerik Reporting. However, RAG optimizations are never being applied, even though I explicitly set `allowRAG`. Based on the network traffic, I noticed that the LLM model I use returns **TRUE** or **FALSE** as a response to the internal prompt that determines whether the user prompt is RAG-worthy or RAG-unworthy.

The rendering extensions are currently loaded by the Telerik.Reporting.Processing.RenderingExtensionManager all at once in the main thread when the report processing starts. This is redundant because one report processing requires one rendering extension to be loaded.

It would be really useful if EntityDataSouce was updated to support Entity Framework Core contexts. EF Core depends on Standard 2.0 so can run on .NET Core or the full framework.

Currently, if I want to see what the device info settings for an extension like the PDF are, I need to open the documentation - Telerik Reporting Configuring the Output Formats PDF Device Information Settings - Telerik Reporting, then copy the setting that I wish to use in my code.

It would be easier and safer if the device information settings for each format were exposed as a public enum/class. On that note, it would also be easier if the available formats were exposed as well, instead of manually typing them. For example:

public static classTelerikDeviceInfoSetting
{
    public static class PDF
    {
        public const string DOCUMENTTITLE = "DocumentTitle";
        public const string DOCUMENTAUTHOR = "DocumentAuthor";
        public const string DOCUMENTSUBJECT = "DocumentSubject";
        public const string DOCUMENTPRODUCER = "DocumentProducer";
        public const string DOCUMENTCREATOR = "DocumentCreator";
    }

    public static class XLSX
    {
        public const string USENATIVEPAGEHEADER = "UseNativePageHeader";
        public const string USENATIVEPAGEFOOTER = "UseNativePageFooter";
        public const string SHOWGRIDLINES = "ShowGridlines";
    }
}

public static class TelerikRenderingExtension

{

public const string PDF = "PDF";

public const string XLSX = "XLSX";

}

In my Graph, I have set the AccessibleRole and AccessibleDescription. The alternative text is read correctly by the Acrobat Reader's 'Read out Loud' functionality.

The problem is that it keeps reading it multiple times.

When generating PDF/UA files, we need to have special objects that are read by an internal system but ignored by screen readers. This cannot be achieved with the existing functionality.

It would be beneficial if we could configure reports so that specific objects inside the generated document are ignored by screen readers. For example, by setting a special value to the AccessibleRole property of a text box.

When I configure a CsvDataSource through the wizard, leave "The CSV has headers" unset (generating dummy column names), then navigate back to select a different CSV file with actual headers and tick "The CSV has headers", the dummy columns from the first file persist instead of being replaced with the real headers from the new file.

When I display a report in a web report viewer, whose service is running on a server where one or more of the used fonts are not available, the first instance of the item(s) that use those fonts is being substituted with another font. The rest of the items do render with the original font, however.

This creates confusion and inconsistency. We should use the substituted font because it's used for measuring when using Print Preview mode in the web viewers, or when rendering to pdf via print/export.

Dear Team,

Currently, the search functionality in the Report Viewer only matches the exact text as it is displayed on the screen. For example, if a value is formatted as "1,469", searching for "1469" yields no results.
Requested Change:
I would like the search functionality to work against the underlying data value. Users should be able to find numeric values even if they don't include the thousands separator (comma) or other formatting in their search query. This would make the report much more user-friendly and consistent with how users expect search to work.
Example:
  • Actual Value: 1469
  • Displayed Text: 1,469
  • Expected Search Behavior: Searching for "1469" should highlight "1,469".

It would be great if you could introduce the ability to create custom reusable color palettes in Telerik Report Designer, so I don't have to declare the same set of colors for each chart I need them.

If you have a lot of graphs in your report then it is more convenient to change the color palette one place.

In the Standalone Report Designer File menu, please add the shortcuts next to menu items, like Ctrl + S for Save and  Ctrl+Shift+S for Save All.

I changed several reports and then wanted to know how to save all reports at once.

When I have multiple reports open in the Standalone Report Designer, I am not able to rearrange/reorder them.

Refer to the tab behavior in Visual Studio, where you can drag one tab and move it to be in front of another tab.

At the moment it's only possible to have your reports in old-fashioned projects.

It should be possible to add/design reports to SDK-style projects. That should work no matter what target framework is (.NET Core, .NET Standard or .NET Framework).

When exporting a report to PDF with EnableAccessibility=True, PAC reports multiple "Invalid use of a 'TD' structure element" errors. The report has a List that contains SubReport items, and each subreport has its own Tables. The generated PDF structure tree places orphan /TD elements directly under /Sect instead of under /TR.

While customising templates/CSS, I noticed the .trv-parameters-wrapper div as follows:

<div tabindex="300" class="trv-parameters-wrapper" aria-label="Parameters area. Contains 4 parameters.">
<div class="trv-parameter-container k-card"></div>
</div>
The report being tested had 1 visible and 3 invisible parameters and one .trv-parameter-container is rendered. Counting 4 being contained in the "Parameters area" does not appear to be too helpful.

I’m working on a project that requires generating Section 508-compliant PDFs, and I’m using Telerik Reporting to build the accessible reports. However, I’ve run into a problem with how screen readers—specifically NVDA—are interpreting table content.

In my report’s table, some values like 12/01/2023 aren’t being read as dates, and values like (192,340.00)—which represent negative numbers—aren’t being interpreted as “negative” or addressing the parenthesis.

I’m working on a project that requires generating Section 508-compliant PDFs, and I’m using Telerik Reporting to build the accessible reports. However, I’ve run into a problem with how screen readers—specifically NVDA—are interpreting table content.
As soon as I set an AccessibleDescription on a cell (especially the first cell in a row), NVDA stops reading the rest of the row. It seems like the table reading order is broken, and the screen reader exits the table structure or skips over the remaining cells to go to the next row.
This is obviously a problem for users relying on screen readers, and I’m not sure how to fix it. Has anyone else dealt with this in Telerik Reporting, or know a workaround to make screen readers read both the custom alt text and maintain proper row navigation?
