Show Print Preview of PDF file in C#

At some point, we may want to display a PDF file as it will appear when printed. This article demonstrates how to show print preview of a PDF file in Windows Forms application using Spire.PDF and c#.

Before using the following code, we need to create a windows forms application, add a PrintPreviewControl control to the form and reference Spire.Pdf.dll into the application.

using System;
using System.Windows.Forms;
using Spire.Pdf;

namespace PreviewPDF
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
               
        private void printPreviewControl1_Click(object sender, EventArgs e)
        {
            //Load PDF file
            PdfDocument pdf = new PdfDocument();
            pdf.LoadFromFile("New Zealand.pdf");

            //Set the PrintPreviewControl.Rows and PrintPreviewControl.Columns properties to show multiple pages
            this.printPreviewControl1.Rows = 2;
            this.printPreviewControl1.Columns = 2;

            //Preview the pdf file
            pdf.Preview(this.printPreviewControl1);  
        }             
    }
}
