            <ColumnDefinition Width="1*"/>
        <syncfusion:PdfViewerControl x:Name="PdfViewer" Grid.Column="0"/>
        <GroupBox VerticalAlignment="Center" Grid.Column="1" Margin="20">
                <TextBlock Text="Coordinates" FontSize="16" FontWeight="Bold"></TextBlock>

        private void PdfViewer_MouseUp(object sender, MouseButtonEventArgs e)
            System.Drawing.Point position = new System.Drawing.Point
                X = (int)e.GetPosition(PdfViewer).X,
                Y = (int)e.GetPosition(PdfViewer).Y
            //Displays the x and y coordinates
            xLabel.Content = position.X;
