8 Dec 20234 minutes to read

The Syncfusion .NET PDF library is used to create, read, and edit PDF documents programatically without the dependency of Adobe Acrobat. Using this library, you can open and save PDF document in WPF.

Steps to open and save PDF document programmatically:

Step 1: Create a new Windows Forms application project.

Step 2: Install Syncfusion.Pdf.Wpf NuGet package as a reference to your Windows Forms application from the NuGet.org.

NOTE

Starting with v16.2.0.x, if you reference Syncfusion assemblies from the trial setup or from the NuGet feed, you also have to add the “Syncfusion.Licensing” assembly reference and include a license key in your projects. Please refer to this link to know about registering Syncfusion license key in your application to use our components.

Step 3: Include the following namespaces in the MainWindow.xaml.cs file.

C#

using Syncfusion.Pdf.Grid;
using Syncfusion.Pdf;
using Syncfusion.Pdf.Parsing;
using Syncfusion.Pdf.Graphics;

Step 4: Add a new button in the MainWindow.xaml to open and save the PDF document as follows.

XAML

<Button Click="btnOpenAndSave_Click" Margin="0,187,0,0" VerticalAlignment="Top" Height="30" BorderBrush="LightBlue" HorizontalAlignment="Center" Width="256">
    <Button.Background>
        <LinearGradientBrush EndPoint="0.5,-0.04" StartPoint="0.5,1.04">
            <GradientStop Color="#FFD9E9F7" Offset="0"/>
                <GradientStop Color="#FFEFF8FF" Offset="1"/>
        </LinearGradientBrush>
    </Button.Background>
    <StackPanel Orientation="Horizontal" Height="23" Margin="0,0,0,-2.52" VerticalAlignment="Bottom" HorizontalAlignment="Right" Width="200">
        <Image Name="image2" Margin="2" HorizontalAlignment="Center" VerticalAlignment="Center" />
        <TextBlock Text="Opend and Save PDF documemt" Height="26" Width="261" />
    </StackPanel>
</Button>

Step 5: Add the following code in the btnOpenAndSave_Click to open an existing PDF document in WPF.

C#

//Open an existing PDF document.
PdfLoadedDocument document = new PdfLoadedDocument("Input.pdf");

Step 6: Add the below code example to add a table in the PDF document.

C#

//Load the page. 
PdfLoadedPage loadedPage = document.Pages[0] as PdfLoadedPage;
//Create graphics for the page. 
PdfGraphics graphics = loadedPage.Graphics;

//Create a PdfGrid.
PdfGrid pdfGrid = new PdfGrid();
//Add values to the list.
List<object> data = new List<object>();
Object row1 = new { Product_ID = "1001", Product_Name = "Bicycle", Price = "10,000" };
Object row2 = new { Product_ID = "1002", Product_Name = "Head Light", Price = "3,000" };
Object row3 = new { Product_ID = "1003", Product_Name = "Break wire", Price = "1,500" };
data.Add(row1);
data.Add(row2);
data.Add(row3);
//Add list to IEnumerable.
IEnumerable<object> dataTable = data;
//Assign data source.
pdfGrid.DataSource = dataTable;
//Apply built-in table style.
pdfGrid.ApplyBuiltinStyle(PdfGridBuiltinStyle.GridTable4Accent3);
//Draw the grid to the page of PDF document.
pdfGrid.Draw(graphics, new RectangleF(40, 400, loadedPage.Size.Width - 80, 0));

Step 7: Add the below code example to save the PDF document in WPF.

C#

//Save the document.
document.Save("Sample.pdf");

You can download a complete working sample from GitHub.
