Step 3: Design the UI for selecting Excel documents

Add the required UI buttons for selecting Excel documents and performing the print operation in the MainWindow.xaml file.

Refer to the following code example.

<Window x:Name="Print_Excel" x:Class="PrintExcelDocuments.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:PrintExcelDocuments"
        mc:Ignorable="d"
        Title="MainWindow" Height="250" Width="532">
    <Grid Margin="3,-1,0,-6" Background="#FFE0E4EB">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="37*"/>
            <ColumnDefinition Width="21*"/>
            <ColumnDefinition Width="81*"/>
            <ColumnDefinition Width="68*"/>
            <ColumnDefinition Width="278*"/>
            <ColumnDefinition Width="44*"/>
        </Grid.ColumnDefinitions>
        <Button Click="PrintExcel"  Content="Print" HorizontalAlignment="Left"  VerticalAlignment="Top" Width="110" Height="27" Margin="47,111,0,0" FontWeight="Bold" Grid.Column="3" Grid.ColumnSpan="2"/>
        <Label Content="Select Excel File" HorizontalAlignment="Left" Margin="24,60,0,0" VerticalAlignment="Top" Width="114" Height="25" FontSize="14" Grid.ColumnSpan="3"/>
        <TextBox Name="filePath" HorizontalAlignment="Left" Margin="4,61,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="195" Height="24" Grid.Column="3" Grid.ColumnSpan="2"/>
        <Button Content="Browse" HorizontalAlignment="Left" Margin="152,61,0,0" VerticalAlignment="Top" RenderTransformOrigin="0.5,0.5" Click="SelectFile" Width="68" Height="24" FontWeight="Bold" FontStyle="Italic" Grid.Column="4"/>
    </Grid>
</Window>

After executing the previous code example, the UI will look like the following image.

        public MainWindow()
        {
            InitializeComponent();
        }

        private void SelectFile(object sender, RoutedEventArgs e)
        {
            //Initializes FileSavePicker.
            Microsoft.Win32.OpenFileDialog openFileDialog = new Microsoft.Win32.OpenFileDialog();
            openFileDialog.Filter = "Excel Files|*.xls;*.xlsx;*.xlsm,*.xltm,*.csv,*.tsv";
            openFileDialog.Title = "Select a Excel File";
            openFileDialog.ShowDialog();

            //Gets the path of specified file.
            filePath.Text = openFileDialog.FileName;            
        }

        private void PrintExcel(object sender, RoutedEventArgs e)
        {
            using (ExcelEngine excelEngine = new ExcelEngine())
            {
                IApplication application = excelEngine.Excel;
                application.DefaultVersion = ExcelVersion.Xlsx;

                //Loads or opens an existing workbook through Open method of IWorkbooks.
                IWorkbook workbook = application.Workbooks.Open(filePath.Text);

                //Initialize the printer settings.
                PrinterSettings printerSettings = new PrinterSettings();

                //Customizing the printer settings.
                printerSettings.PrinterName = "HP LaserJet Pro MFP M127-M128 PCLmS";
                printerSettings.Copies = 2;
                printerSettings.FromPage = 1;
                printerSettings.ToPage = 3;
                printerSettings.DefaultPageSettings.Color = true;
                printerSettings.Duplex = Duplex.Vertical;
                printerSettings.Collate = true;

                ExcelToPdfConverter converter = new ExcelToPdfConverter(workbook);

                converter.Print();
            }
