Right to Left (RTL) in WPF PDF Viewer

25 May 20261 minute to read

The Syncfusion^® WPF PDF Viewer control supports right-to-left (RTL) rendering. All user interface elements are displayed based on left-to-right (LTR) or right-to-left (RTL) direction, ensuring proper layout and alignment for RTL languages.

Enabling RTL in WPF PDF Viewer

RTL can be configured in the WPF PDF Viewer using the FlowDirection property. This can be set either in XAML or in the code-behind (C#).

Configuring RTL in XAML

RTL can be enabled in XAML by setting the FlowDirection property to RightToLeft.

XAML

<Grid>
    <PdfViewer:PdfViewerControl x:Name="pdfViewer" FlowDirection="RightToLeft"/>
 </Grid>

Configuring RTL in Code-Behind (C#)

RTL can also be configured programmatically by setting the FlowDirection property in the code-behind. Refer the following code snippet.

C#

namespace RTLSample
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            pdfViewer.FlowDirection = FlowDirection.RightToLeft;
            pdfViewer.Load("../../../Data/RTLText.pdf");

        }
    }
}

NOTE

The sample project to perform the operation is available in the GitHub.
