Globalization and RTL in Blazor PDF Viewer Component

17 Jan 202213 minutes to read

The PDF Viewer component allows to localize the static text on formatting pane, toolbar, dialog and more. It can be achieved by setting the Locale property and providing the localized text through the LoadLocaleData() method.

Also, this component provides support to render the user interface suitable for users who use right-to-left (RTL) languages (Arabic, Hebrew, Azerbaijani, Persian, Urdu). You can specify the control to render in RTL by setting the EnableRtl property to true.

The following code snippet shows how to localize the component for Arabic language by setting the Locale and EnableRtl properties and providing the localized text.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.PdfViewerServer


<SfPdfViewerServer Width="1060px" Height="500px" DocumentPath="@DocumentPath" EnableRtl="true" Locale="ar-AE" />

@code{
    public string DocumentPath { get; set; } = "wwwroot/data/PDF_Succinctly.pdf";
    [Inject]
    protected IJSRuntime JsRuntime { get; set; }
    protected override void OnAfterRender(bool firstRender)
    {
        this.JsRuntime.Sf().LoadLocaleData("wwwroot/locale.json");
    }
}

The following table shows the default text values used in PDF Viewer in ‘en-US’ culture:
