Currently, page breaks in reports are static and cannot adapt to dynamic conditions during rendering. This limitation makes it challenging to format highly variable reports where layout requirements depend on runtime data or page positioning.

The requested feature would allow developers to define expressions or rules that determine whether a page break should occur, considering factors such as:

• The current page number
• The position of a specific control on the page
• Other Internal report variables

Benefits

• Enables precise control over report layout for complex, data-driven scenarios
• Improves usability for industries requiring strict formatting standards (e.g., financial, healthcare, compliance reporting)
• Aligns functionality with competitive reporting tools like Crystal Reports, enhancing product competitiveness
• Reduces manual workarounds and simplifies report design for advanced pagination needs

Similar, but more specific request already exists:

I have a string parameter with `autoRefresh` set to `true`. In the report viewer, it displays a textbox as a parameter editor. However, the report viewer refreshes on every "keydown" event, which can be frustrating for users. In the Standalone Report Designer, the report is refreshed only after the textbox is unfocused.

I have cascade parameters that depend on other parameters (check the Product Line Sales report for an example). I have set these parameters with `autoRefresh` of `false`. In the Standalone Report Designer, once I change the value of a parameter, the dependent parameter also changes automatically. However, this is not the case in the Native Angular report viewer.

I have 2 Date parameters on my report. The "Start Date" parameter defaults to today, and the "End Date" defaults to the "Start Date" + 1 Year.

This works fine in the Report Designer, e.g., when the Start Date is changed in preview mode, the End Date value is recalculated.

However, this behavior does not work in the Blazor Native Report Viewer.  When the page first renders, the two dates are shown correctly, but if the Start Date is changed, the End Date is not recalculated.

My use case is a multi-select parameter that is based on a dataset; and the dataset is filtered by 2 other parameters.

The dependent parameter editor is shown as a SpinButton rather than a multi-select editor in the Blazor Native Report Viewer:

When adding an embedded image to a coded report in the Standalone Designer .NET, the original RESX file is not modified.

Only the original DESIGNER.CS file is modified. This leads to the new PictureBox being present but empty after deleting the dedicated folder named after the report (beside the designer EXE).

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 have successfully installed the ODBC and OLEDB providers for Visual FoxPro 9 and they appear in the Windows 32-bit ODBC Data Sources under System DSN.

The drivers are discovered when I use Standalone Report Designer x86 from 17.2.23.1114 and older ones built against .NET Framework 4.0.

The same drivers are not found on the same machine when I use Standalone Report Designer x86 from 18.3.24.1218 built against .NET Framework 4.6.2.

I use the kendovalidator before rendering the report to check the correct parameter of initial and final date.

 

However, the validation fails because additional inputs (for the "Send Email" functionality) are included in the HTML output of the viewer even though I have disabled it.

 

I believe that if the "Send Email" option is disabled the mail data panel should not be created.

All of my report parameters have their AutoRefresh setting set to False, and the parameters do not depend on each other, they are not cascading parameters. The parameters have available values.

If I change the value of one of the parameters, despite the above settings, all of the other parameters' data is re-retrieved(even if those parameters are not visible).

This causes issues because the "Preview" button is disabled until the parameters are refreshed, and makes the UX bad since if the connection is slow, the end-users will have to wait for the parameters area to refresh after changing any parameter value.  

Rendering ReportBook item may result in incorrect page number, the total page count being less than the actual pages.

I have a generate button to create the report programmatically, with my own form and controls that are sent as parameters.  I do not want the report to render immediately as the user needs to select the parameters first.  

When a system tells users they should look into the report parameters as the reason the report isn't displaying.  It's reasonable for your users to believe you aren't misleading them. 

The report viewer error message misleads users.  In reality the parameters are correctly configured and it the repot URL could be wrong.  Or a variety of other issues are at play; for instance, a problem with you connection string will also return the "Unable to get report parameters" error message.  I'd like to see this error message at minimum changed to "report can't display."   It's better to throw out a generic message vs having users spend hours or days troubleshooting the report parameters.  Better yet a proper catch/validation system put into place please.  

If cells grow or shrink, if there are hidden cells, any time a report section grows vertically, the next section/table is not respecting the growing of the previous item and text prints in the wrong spot or the table overlaps the previous table.

A potential workaround is to manually convert the troublesome tables to lists where possible.

As soon as I reference a .NET 10 assembly containing models, there is a null reference exception that does not appear in EventViewer or Fusion logging at the opening of the Standalone Report Designer for .NET.

Here is a link to a muted video demonstrating how adding assembly references using the UI successfully adds the custom assembly to the designer, as well as the bug when removing the assembly version.

As of now the Reporting team provides only part of the source code - mostly the code that targets .NET Framework 4.6.2.

Please expose more of the code to your customers, like Telerik Reporting engine for .NET 6+ and corresponding REST WebAPI.

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 use an approved government font for the reports. I have specified it in the `privateFonts` option of the report engine configuration. However, on Linux, it is not picked up during rendering. In FontForge, the font shows the following warning:

On Windows, it causes no issues.

Please add support for the newly released Angular 20 for both of the Angular Report Viewers.

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.
