How to apply localization for a WPF PdfViewer hosted in WinForms Application

To implement localization for the WPF PDF Viewer embedded within a WinForms application, the process involves hosting the WPF PDF Viewer in WinForms. For guidance on hosting, refer to the Hosting WPF in WinForms documentation.

To accomplish localization, begin by creating a new class library within your WinForms solution. Inside this library, create a folder named “Resources” and add the necessary .resx files for localization. Then, reference this class library in your WinForms project. In the WPF UserControl hosting the PDF Viewer, include code to load and apply localization resources from the referenced assembly.

Steps to Apply Localization for a WPF PDF Viewer Hosted in a WinForms Application

Step 1:
Create a new class project and add a “Resources” folder to the class project. Place the default English resource file (Syncfusion.PdfViewer.WPF.resx) in the Resources folder. Create additional .resx files to support different cultures. For example:

• Syncfusion.PdfViewer.WPF.en.resx for English
• Syncfusion.PdfViewer.WPF.fr.resx for French

Step 2:
In each .resx file, define the required resource keys and their corresponding localized values. Add the created class library as a reference to your WinForms application.

Step 3:
Create a WPF UserControl that includes the PdfViewerControl. Embed this control into the WinForms application using ElementHost. Configure localization by linking the external resource assembly using the LocalizationManager.SetResources method.

// Set the custom class library assembly and namespace for localization
LocalizationManager.SetResources(
    typeof(LocalizationClassLibrary.Class1).Assembly,
    "LocalizationClassLibrary"
);

// Load the document
pdfViewer.Load(@"../../Data/F#.pdf");
