How to create remote GoTo action in ASP.NET Core PDF using C#?

The Syncfusion Essential® PDF is a feature-rich and high performance .NET PDF library used to create, read, and edit PDF documents programmatically without Adobe dependencies. Using this library, you can set the remote goto action for the link annotation in a PDF document using C#.

Steps to add remote goto action for the link annotation in a PDF document programmatically:

1. Create a new console application project.
2. Install the Syncfusion.Pdf.Net.Core NuGet package as a reference to your console application from Nuget.org.
   
3. Include the following namespaces in the Program.cs file.

C#

using Syncfusion.Pdf;
using Syncfusion.Pdf.Parsing;
using Syncfusion.Pdf.Interactive;

VB.NET

Imports Syncfusion.Pdf
Imports Syncfusion.Pdf.Parsing
Imports Syncfusion.Pdf.Interactive 

4. Use the following code sample in Program.cs to set the remote goto action for the link annotation in a PDF document.

C#

// Open the PDF document from a file stream
PdfLoadedDocument document = new PdfLoadedDocument(File.OpenRead(@../../../"Invoice.pdf"));
// Access the first page of the loaded document
PdfLoadedPage page = document.Pages[0] as PdfLoadedPage;
// Create a URI annotation at specified coordinates on the page
PdfUriAnnotation uriAnnotation = new PdfUriAnnotation(new Syncfusion.Drawing.RectangleF(100, 160, 100, 20));
// Set the text for the URI annotation
uriAnnotation.Text = "Uri Annotation";
// Set the border for the URI annotation
uriAnnotation.Border = new PdfAnnotationBorder(1);
// Set the URI (destination) that the annotation will link to
uriAnnotation.Uri = "HeaderAndFooter.pdf";
// Create a new remote destination for navigation
PdfRemoteDestination remoteDestination = new PdfRemoteDestination();
// Set the remote page number to navigate the remove file page
remoteDestination.RemotePageNumber = 5;
// Set the mode for the destination (here, it's set to fit the page)
remoteDestination.Mode = PdfDestinationMode.FitToPage;
//Create a new PdfRemoteGoToAction
PdfRemoteGoToAction goToAction = new PdfRemoteGoToAction("HeaderAndFooter.pdf", remoteDestination);
//Set the IsNewWindow
goToAction.IsNewWindow = true;
//Add the action to the link annotation
uriAnnotation.Action = goToAction;
page.Annotations.Add(uriAnnotation);
//Save the document into stream
MemoryStream stream = new MemoryStream();
document.Save(stream);
//Close the document
document.Close(true);
File.WriteAllBytes("Output.pdf", stream.ToArray());

VB.NET

'Open the PDF document from a file stream
Dim document As New PdfLoadedDocument(File.OpenRead("Invoice.pdf"))
'Access the first page of the loaded document
Dim page As PdfLoadedPage = TryCast(document.Pages(0), PdfLoadedPage)
'Create a URI annotation at specified coordinates on the page
Dim uriAnnotation As New PdfUriAnnotation(New RectangleF(100, 160, 100, 20))
'Set the text for the URI annotation
uriAnnotation.Text = "Uri Annotation"
'Set the border for the URI annotation
uriAnnotation.Border = New PdfAnnotationBorder(1)
'Set the URI (destination) that the annotation will link to
uriAnnotation.Uri = "HeaderAndFooter.pdf"
'Create a new remote destination
Dim remoteDestination As New PdfRemoteDestination()
remoteDestination.RemotePageNumber = 5
remoteDestination.Mode = PdfDestinationMode.FitToPage
'Create a new PdfRemoteGoToAction
Dim goToAction As New PdfRemoteGoToAction("HeaderAndFooter.pdf", remoteDestination)
'Set the IsNewWindow property
goToAction.IsNewWindow = True
'Add the action to the URI annotation
 uriAnnotation.Action = goToAction
 page.Annotations.Add(uriAnnotation)
'Save the document into a memory stream
 Dim stream As New MemoryStream()
 document.Save(stream)
 stream.Position = 0
 File.WriteAllBytes("Output.pdf", stream.ToArray())
 'Close the document
 document.Close(True)
