We have spotted that PInvoke is now marked as deprecated (this applies even to the latest 0.7.124 version). In the description of the PInvoke.User32 NuGet package, it is mentioned that Microsoft.Windows.CsWin32 should be used instead:

Please consider replacing the deprecated package.

Summary

When the Web Report Designer is initialized with non-English string resources (via window.telerikWebDesignerResources), the authentication type selector in the Web Service Data Source wizard behaves incorrectly. Even though "Sin autenticación" (the translated value of WebServiceDataSourceNoAuthentication) is visually selected in the dropdown, the wizard behaves as if a different authentication type is selected — displaying additional required credential fields and blocking progression.

The issue does not occur when using English string resources (WebServiceDataSourceNoAuthentication = "No authentication").

---
Steps to Reproduce

1. Configure a Blazor Web Report Designer with Spanish (es-CO) custom string resources using window.telerikWebDesignerResources:

// WebReportDesignerStrings.es-CO.js
export class WebReportDesignerStringsBase {
    constructor() {
        // ...
        this.WebServiceDataSourceNoAuthentication = "Sin autenticación";
        // ...
    }
}

// Load resources before designer renders
window.telerikWebDesignerResources = new WebReportDesignerStringsBase();

2. Open the Web Report Designer in the browser with the Spanish resources active.
3. Add a new Web Service Data Source.
4. In the wizard URL step, observe the authentication selector — it shows "Sin autenticación" as the selected option.
5. Attempt to proceed through the wizard.

---
Expected Behavior

With "Sin autenticación" selected (equivalent to "No authentication"), the wizard should:
- Require only the Service URL field
- Not display credential input panels
- Allow proceeding to the next step without authentication configuration

---
Actual Behavior

Despite "Sin autenticación" being visually selected, the wizard behaves as if a different authentication type (Basic or 2-step) is selected:
- Additional authentication configuration panels appear or are required
- The wizard blocks progression expecting credential inputs
- The behavior is identical to what occurs when "Basic" or "2-step" is selected

---
Root Cause Analysis

The designer's compiled JavaScript (webReportDesigner) appears to compare the selected authentication type against the English string "No authentication" internally, rather than against a stable enum or index value. When the display text is "Sin autenticación", this comparison fails and the wizard falls through to a non-"no auth" code path.

Evidence: applying the temporary workaround of keeping WebServiceDataSourceNoAuthentication = "No authentication" (English text) in the es-CO resources file resolves the issue completely — the wizard functions correctly while all other strings remain in Spanish.

---
Workaround

In the non-English string resources file, keep WebServiceDataSourceNoAuthentication in English:

// workaround: keep English value until Telerik fixes internal comparison
this.WebServiceDataSourceNoAuthentication = "No authentication";

---
Minimal Reproduction

@* ReportEditor.razor *@
@page "/reportEditor"
@using Telerik.WebReportDesigner.Blazor

<WebReportDesigner DesignerId="wrd1"
                   ServiceUrl="apiReport/reportdesigner" />

// Loaded before designer renders via IJSRuntime.InvokeVoidAsync
window.telerikWebDesignerResources = {
    WebServiceDataSourceNoAuthentication: "Sin autenticación",
    // ... other keys
};


---
Additional Notes

- Both es-CO and en-US string resource files contain 971 keys each — the issue is not caused by missing keys.
- The designer correctly picks up the localized strings for all other UI elements; the bug is isolated to the authentication dropdown value comparison logic.
- Confirmed on version 19.1.25.521; not tested on earlier versions.

thank for your attention.

have a nice day.

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.

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";

}

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.

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.

React Report Viewer throws error ts(7016) on importing it in a TypeScript project:

Could not find a declaration file for module '@progress/telerik-react-report-viewer/dist/cjs/main'. 'C:/Users/dnikolov/Desktop/ReactTypesScript/my-app/node_modules/@progress/telerik-react-report-viewer/dist/cjs/main.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/progress__telerik-react-report-viewer` if it exists or add a new declaration (.d.ts) file containing `declare module '@progress/telerik-react-report-viewer/dist/cjs/main';`

The attached report generates different PDF documents when rendered by the Standalone Designer and REST Service, both targeting the .NET Framework 4.6.2:

• The PDFs have different sizes
• When using the 'Read out loud' functionality of the Adobe Reader, the items are read in a different order. The order in the PDF generated by the designer is correct, and the one in the service-generated PDF is wrong.

Currently, logarithmic axes do not support the LabelStep and MajorStep properties, which makes it difficult to control label density and avoid visual clutter for larger data ranges.

Adding support for these settings (similar to numerical scales), or providing a way to conditionally hide axis labels, would significantly improve readability and axis customization.

I have a Telerik report designed in the Standalone Report Designer. In the HTML5 Report Viewer, the report seems to be correct, but when I export the report in PDF, the word order changes.

The problem occurs in the HTMLTextBox when rendering in PDF and previewing in the Standalone Designer with both Skia and GDI+.

In the TextBox, the same text is displayed as expected.

When previewing in the HTML Report Viewer, the Arabic text seems fine.

When using A4 paper or narrow-edge leading media the Web Viewer prints everything perfectly.

When using a 60mm x 30mm label, therefore "wide-edge" leading media, the web viewer prints the label in landscape, even though the print is in portrait!

Just because the media is "landscape" surely it is the print on the media that determines the orientation?

When using the Windows System Print Dialogue this does not occur, on the using the print from the Web Viewer. This is because the Web Viewer converts it to PDF first to print (I believe). Surely, in the code you can state NOT to rotate, OR rotate it back to the correct orientation for wide edge leading media.

The label design is portrait so all the "print / pdf" code needs to do is to query this and not assume that wide edge leading media automatically prints in landscape.

When using the SqlDataSource component with a stored procedure that has an IF-ELSE condition which selects a different set of columns depending on whether the condition is true or false, the returned data schema is always as if the condition is evaluated to true.

While the schema is wrong, if I manually type the fields, at runtime, they get resolved correctly but it is inconvenient.

WPF report viewer crashes when launching it the second time. The issue appears to occur only when having a trial license activated.

System.Windows.Data Error: 23 : Cannot convert '<null>' from type '<null>' to type 'System.Uri' for 'en-US' culture with default conversions; consider using Converter property of Binding. NotSupportedException:'System.NotSupportedException: UriTypeConverter cannot convert from (null).

I want to set the Table ColumnWidth to a particular value in the Properties of the Web Report Designer. There is no property ColumnWidth as in the Desktop designers, and I tried to set the Size.Width, which is available.

When I increased the Width from the Properties, in design time, there is no change in the column width, only dashed borders indicating the new size when selecting the corresponding TextBoxes. In runtime, though, the new size is respected.

The inconsistency repeats even when I open the saved report in another browser or through another application, hence this is not a caching issue.
