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.

If we initialise the control in "FIT_PAGE_WIDTH" mode it essentially renders as expected but zooming in can actually then cause it to zoom *out*.

Reproducible in the `CSharp.NetFramework.Html5IntegrationDemo` example project as well, once you set the `scaleMode` property to "In FIT_PAGE_WIDTH".

In print preview, if you have "FIT_PAGE_WIDTH" as a default scale mode, once you click the "toggle full page/full page width" button, it's never possible to get it to return the original fit-page-width size (it seems to cycle between 3 different zoom modes, but none of them fill the entire control width).

It looks like the report viewer correctly sets the scale mode during initialization. However, when toggling the mode later, it sets it incorrectly.

If I try to drag & drop fields in the Standalone Report Designer for .NET, it does not allow me to paste the field, and the icon changes, indicating that the action is not allowed.

On the other hand, I can drag & drop the fields as expected when using the Standalone Report Designer for .NET Framework.

I have updated to version 19.2.25.813 of Reporting, and when I try to build a project that has Reporting references, I get the following warnings:

Telerik and Kendo UI Licensing warning TKL102: Your current license has expired and is not valid for Telerik Document Processing Libraries version 2025.2.807.20.

There are no Telerik Document Processing dependencies in my project, but I still get the warning.

Currently, the VS item templates, and the documentation suggest using app.UseEndpoints for route registration in ASP.NET Core.

It would be better to use top-level route registrations like app.MapControllers() and app.MapControllerRoute() directly.

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:

Hi Team,

Currently, the DatabaseCacheConfigurator.exe tool seems to be Windows-only. Can you please compile this to be cross platform compatible? I am on macOS and cannot use any Windows tooling.

Thank you,

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>

If I set the ReportSource to the Native Blazor Report Viewer using @bind directive, for example:

@bind-ReportSource="@ReportSource"

ReportSource="@(new ReportSourceOptions { ... })"

It causes the viewer to go into a loop of trying to set the ReportSource, and it never renders the report.

We use WPF Report Viewer in our application. For testing, validation, and automation purposes, we need to:

• Uniquely identify each element in the XAML rendered report contents to support automation.
• Prevent the element ID changes. The generated item IDs must remain consistent as long as the report definition is not changed.

Hi Team,

I have a request for being able to add the `User-Agent` header to reporting calls. We've ran into some image hosting sites that will not resolve image links properly if the user-agent is not present in the request and returns a 403 Forbidden error. Any browser that passes the user-agent parameter can resolve this link.

But telerik will return this error:

Telerik.ReportDesigner.exe Error: 0 : An exception has occurred while processing 'pictureBox1' item:
System.Net.WebException: The remote server returned an error: (403) Forbidden.

   at Telerik.Reporting.Processing.PictureBox.ResolveImage(Object value)
   at Telerik.Reporting.Processing.ReportItemBase.ProcessElement()
   at Telerik.Reporting.Processing.ProcessingElement.Process(IDataMember dataContext)

Currently, the only way around this is to fetch the images with a custom user function and returns the images to the Reporting Engine as a byte array or other supported format. It's a lot of overhead for something that could simply be toggled on an off, so I think this would be a nice feature addition. 

Thanks,
J.T.

If I set both the "EnableAccessibility" and "ViewerRenderToolTips" device info settings to true, the generated PDF document is corrupted.

I am using the NPM package rxjs@6.6.7 together with @progress/telerik-angular-native-report-viewer26.25.521. The latter has the following peer dependency listed in its `package.json`:

"rxjs": "^6.5.3 || ^7.4.0"

Version 6.6.7 is within this range, but when running the application, I get errors, such as:

Error: export 'take' (imported as 'take') was not found in 'rxjs

Hi Support team,

On ServerSide, when using a CultureInfo, with a NumberSeperator different then '.', e.g. CultrerInfo("de-DE"), it is not possible to Save a report.

It seems it is internally converted to a string based value and gets the different seperator and than can not be casted/converted back to double.

My project uses the following two dependencies:

• Telerik.UI.for.Blazor (v9.1.0)
• Telerik.ReportViewer.BlazorNative (v19.1.25.716)

However, when I build my application and navigate to the page of the Native Blazor report viewer, the following error is thrown:

“Telerik.Blazor.Components.TelerikWindow does not have a property matching the name ‘Centered’.” at Microsoft.AspNetCore.Components.Reflection.ComponentProperties.ThrowForUnknownIncomingParameterName(Type targetType, String parameterName) at Microsoft.AspNetCore.Components.Reflection.ComponentProperties.SetProperties(ParameterView& parameters, Object target) at Microsoft.AspNetCore.Components.ParameterView.SetParameterProperties(Object target) at Microsoft.AspNetCore.Components.ComponentBase.SetParametersAsync(ParameterView parameters) at Telerik.Blazor.Components.TelerikWindow.SetParametersAsync(ParameterView parameters) at Microsoft.AspNetCore.Components.Rendering.ComponentState.SupplyCombinedParameters(ParameterView directAndCascadingParameters)

Actually Axis title can move only on his specific axis.

For example, x-axis title can move left to right and y-axis title can move up to down.

But in same cases, like mine, where the axis are not on the edge of the chart (because it involves negative x and y values and the intersection is in the middle of the field) it is necessary to move the x-axis title up and down to be next to the x-axis position, or to move y-axis left/right to be next to the y-axis position.

Feature request: allow axis titles to be moved on both axis and not only one.

In attach you'll find a screen that shows the desired result.

Best regards
