Hi Team
We purchased a reporting component and need to use a table of contents for our reports
The table of contents does not support right to left - for Hebrew/Arabic language
This is really problematic and seems to me a basic need that should be included in the service
We expect a solution soon
Thank you

I have a case where I need to allow the hyphen (-), but currently I don't have a way to remove this character from the rule to add the FormulaPrefix.

I would like to request the addition of FormulaPrefixCharacters.

I'm using the WinUI Report Viewer in my .NET 8 WinUI3 desktop application.  All my reports initially render and display correctly, however, when the user clicks on the Print Preview button to switch to the print preview view, it causes my app to crash. This only occurs when using Versions 19.1.25.521 and above of the Telerik.ReportViewer.WinUI package. If I roll the NuGet back down to versions 19.0.25.313 and below, my application happily switches between interactive and print preview view without error.

Interestingly, if I force the Report Viewer to start in print preview view (with ViewMode="PrintPreview" in the xaml), it displays without error (though the toolbar print preview button is not showing as being toggled).  I can then also switch to interactive mode once without error by toggling the print preview button. However, if I then attempt to switch back to the print preview mode, it again crashes.

I have a .NET project. I tried to add a CS-based report to it using the Visual Studio item template. However, when I opened it, I encountered an error message, which wasn't helpful.

After reaching out to the technical support, I was told that the Visual Studio Report Designer was not supported in .NET projects, and the alternative was either to open the CS-based report through the Standalone Report Designer or use TRDP reports (recommended for new reports) instead.

It would be nice if there were some warning about this, as it would save me some time and confusion, as at first, when I encountered the error message, I took the assumption that something was corrupted with my project.

Hi Team
We are using the Telerik Reporting component and are very happy
We really wanted to use the Table of Contents component in our reports
The Table of Contents works great but unfortunately does not support right-to-left in Hebrew
I guess for you this is a small fix and for us it will be a big relief
We ask for your help and improve the component for us so that the wonderful Table of Contents supports right-to-left
Thank you
Tamar

Hi,

Currently, if Thread.CurrentThread.CurrentCulture set to tr-TR (can be also reproduced with az-AZ and maybe some other cultures) some tags are ignored in HtmlTextBox, but they work if typed in UpperCase. This can be reproduced with any supported tag which contains letter "i" like "div" or "li".

For example, we have two ol list but one with LI and the other one with li tags:

<ol>
  <LI>first</LI>
  <LI>second</LI>
</ol>

<ol>
  <li>first</li>
  <li>second</li>
</ol>

This is how it is rendered in PDF:

When the current thread culture is set to Turkish (tr-TR), the lowercase and uppercase conversion rules differ from English — especially for the letter "i".

• In Turkish:

  • "i".ToUpper() → İ (with a dot)

  • "I".ToLower() → ı (dotless i)

Our assumption that the Telerik HtmlTextBox internally parses and maps HTML tags by converting them to uppercase. When the Turkish culture is active, this conversion causes tag names to break, which is not a valid tag, so ordered lists fail to render.

Best regards,
Denis

ADA Accessibility is a priority for our customers, so we are aiming to ensure logical tabbing order for keyboard users.

I've noticed that the RowHeadersPrintOnEveryPage attribute, while very useful for creating more readable PDF exports, seems to result in some strange screen reader behavior when set to True.

The first problem is with the strange tabbing order in the live environment. The second column header is the first to receive focus, followed by the remaining column headers, then the data fields under the first column receive focus in a vertical list, until finally the first column header receives focus. Without the default RowHeadersPrintOnEveryPage setting (False), the first column header is the first to receive focus, which is expected. 

In addition to the wrong tabbing order, the RowHeaderPrintOnEveryPage causes the screen reader to announce the incorrect column associated with a particular cell. I use the Windows Narrator. Other screen readers may result in slightly different behavior. 

The Telerik Web Forms Report Viewer Form VS item template does not install the Telerik.Reporting.Services.WebApi package. However, the controller created with this template has a using statement for it.

Steps To Reproduce

1. Create a new Web Forms project.
2. Right click on the project name > Add > New Item...
3. Choose Telerik Web Forms Report Viewer Form <REPORTING_VERSION>.
4. Build the project.

Expected behavior
The build succeeds.

Actual behavior
The build fails due to the missing package.

Currently, the is permission for disabling saving, but it disables only the "Save" button.

I would like to be able to disable the "Save As" button and keep the "Save" button active, or vice-versa.

The data source of my report contains grouping string values, among which are the '10000' and '1010Q'. These two values are always treated as the same string, and the corresponding records fall within the same report group, which is unexpected:

 

Use SqlDataSource SelectCommand xml element instead xml attribute - it allows to write complex sql requests in any tool and just put it into xml without changes and have it well-formatted and readable:

So, instead of

save it as

 

or even

WebReportDesigner (Blazor) - permission to restrict "Build new data connections" and allow to use only "Select from existing data connections".

It isn't required, but would be nice have button "Test connection" in the bottom enabled to verify predefined connection

Currently, the WinForm report viewer fetches configuration (specifically the connection string for any named connection strings defined in reports) directly from appsettings.json, however, it would be useful if the report viewer could take into account an injected IConfiguration since there are scenarios where the configuration may not exist in appsettings.json or a preferred or more up to date user selected value has been added to the configuration from a different source (such as a userSettings.json or secrets.json).

Some background of my use case:

I have a desktop WinForms application targeting .NET 8.0. It usesTelerik.Reporting 19.2.25.813 and Telerik.ReportViewer.WinForms 19.2.25.813 to display reports.

The reports are TRDX files designed with the 64-bit version of "Report Designer".  The report viewer is being displayed in a dedicated WinForm named FrmReport which configures the reportViewer control to use a UriReportSource pointing to the folder on the user's C:\ drive containing the report files. The reports are designed to use a named connection called ReportsConnection which is configured/saved as a shared connection with Alias ReportsConnection in Report Designer.

The default reports connection string is saved in the appsettings.json file.  Upon application startup users select a database connection from a list of saved/remembered connections and the desktop WinForms application saves the user selected ReportsConnection to a configuration file named userSettings.json.  Both appsettings.json and userSettings.json are configured as sources for IConfiguration with reloadOnChange = true.  After a user selects a database connection and the selected connection string is written to userSettings.json, the configuration is reloaded so that the injected IConfiguration from the service container will have the new, user selected value for ReportsConnection.  At this point, IConfiguration has the updated the named ReportsConnection with the desired connection string, which almost always differs from the default one defined in appsettings.json.

However, when loading the reportViewer, the reports unconditionally connect to the server and database defined in the default connection string from appsettings.json, not the user-selected connection string even though the injected IConfiguration has the updated user selected connection string.

Currently, the only way to set ObjectDataSource parameters as nullable is by typing this manually in the `DataType` property as follows:

Consider allowing to do this through the "Edit Parameters" dialog:

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.

In the latest version (19.2.25.924), adding assembly references for assemblies with no public key raised the error "Object reference not set to an instance of an object", and the designer restarts. This error then occurs every time I open the designer, with Options => Assembly References no longer visible.

We are looking for SBOMs in either CycloneDX or SPDX format to support our internal compliance and security processes.

I have enabled accessibility in my report viewer. The majority of the items do not cause any issues when using a11y scan tools like "Accessible Web Helper". However, shapes and empty text boxes are rendered without a "role" attribute, but with "aria-label", which causes conflicts with the a11y tool I am using. It states "aria-label attribute cannot be used on a div with no valid role attribute".

I cannot localize the messages of the Angular and React report viewers using the suggested approaches:

• Angular Report Viewer Localization - Telerik Reporting
• Localizing the React Report Viewer - Telerik Reporting

The only alternative is to use the approach from the Localization of the HTML5 ReportViewer Explained - Telerik Reporting article, which I can do only by loading the string resources script in index.html of the SPA.
