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:

• PictureBox Report Item Overview

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.

The RTF rendering automatically switches to the Tables rendering mode whenever a Crosstab/Table/List is detected in a report. This rendering mode throws an exception whenever the report contains PictureBox with one of the following sizing options.

• Center
• Normal
• Stretch
• ScaleProportional

The RTF export should work with all PictureBox sizing options regardless of the rendering mode.

To work around the issue currently, one can either force the rendering engine to use the Frames rendering mode using the RenderingMode device information property or set the Sizing property of all picture boxes in the report to AutoSize.

If I render a report that includes a HtmlTextBox item with line breaks in its value(<br />) to PDF with the Skia graphics engine and a font such as DejaVu Sans, the <br /> tags are rendered as squares.

Sample HTML:

<p>line1<br />line2<br /><i>line3</i></p>

Using a font such as Arial, there are no such issues. However, before 2024 Q4, it wasn't a problem when using the DejaVu Sans font as well.

Hi,

I've attached the following abstraction that I made which renders pdfs using a TRDP file.

In an environment where we're bulk generating documents, this falls over as the returning code can return documents from other threads.

This solution is fixable by adding in a lock (commented out in the example), but it degrades the performance quite a bit and users wouldn't expect this behaviour.

This has been reported previously: https://www.telerik.com/forums/is-the-reportprocessor-renderreport-function-thread-safe

I'm using the 2025.1.205 NuGet Packages.

Regards,

Hayden

Hello,

I see from support threads that Telerik really resists any changes to their concept of CSV rendering.  And I also understand the reasoning in not changing any default behavior due to its potentially unwanted effect on established customers.

That said, I wonder if the ability to exclude hidden objects (TextBoxes for example) has been proposed and is in the list of potential enhancements.  I wouldn't mind if it required a configuration setting like NoHiddenObjects = True where the default is False.

Has that been considered?

If I put the following content in an HtmlTextBox, when I open the preview mode of the designer or look at it in the Html5 Report Viewer I get annoying extra gaps:

<p>Comment</p><p>Comment</p><ol><li>List</li><li>List</li><li>List</li></ol><p><br></p><p>Comment</p><p>Comment</p>

I tried to replace these <p>-tags with <div>-tags:

<div>Comment</div><div>Comment</div><ol><li>List</li><li>List</li><li>List</li></ol><div><br></div><div>Comment</div><div>Comment</div>

It helps. But there are some other tags that cannot be replaced (tags of ordered and unordered lists for example). And these gaps are still rendered.
