Right to Left (RTL) in WinForms PDF Viewer

10 Jul 20261 minute to read

The WinForms 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.

Code Changes for Enabling RTL

To enable RTL support in the WinForms PDF Viewer, set the RightToLeft property of the PDF viewer control to Yes. Refer to the following code snippet.

using System.Windows.Forms;

namespace WindowsFormsApp_RTL
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            // Enable RTL layout for PDF Viewer control
            pdfViewerControl1.RightToLeft = RightToLeft.Yes;
        }
    }
}

The following screenshot shows the RTL-enabled PDF Viewer output
