Remarks

Create a Hyperlink

Use the HyperlinkCollection.Create method to add a new hyperlink to the collection.

The code snippet below finds a specific range in the document and converts it to a hyperlink with the specified URI and tooltip:

C#

using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;

using (var wordProcessor = new RichEditDocumentServer())
{
  wordProcessor.LoadDocument("Documents//Document.docx");
  Document document = wordProcessor.Document;

  // Find a specific text string
  DocumentRange[] foundRanges =
          document.FindAll("DevExpress WinForms Rich Text Editor",
  SearchOptions.CaseSensitive);

  if (foundRanges.Length > 0)
  {
      // Convert the found range to a hyperlink
      Hyperlink hyperlink =  document.Hyperlinks.Create(foundRanges[0]);

      // Specify the URI and the tooltip
      hyperlink.NavigateUri =
           "https://www.devexpress.com/Products/NET/Controls/WinForms/Rich_Editor/";
      hyperlink.ToolTip = "WinForms Rich Text Editor";
  }
}

VB

Imports DevExpress.XtraRichEdit
Imports DevExpress.XtraRichEdit.API.Native

Using wordProcessor = New RichEditDocumentServer()
  wordProcessor.LoadDocument("Documents//Document.docx")
  Dim document As Document = wordProcessor.Document

  ' Find a specific text string
  Dim foundRanges() As DocumentRange =
       document.FindAll("DevExpress WinForms Rich Text Editor", SearchOptions.CaseSensitive)

  If foundRanges.Length > 0 Then
      ' Convert the found range to a hyperlink
      Dim hyperlink As Hyperlink = document.Hyperlinks.Create(foundRanges(0))

      ' Specify the URI and the tooltip
      hyperlink.NavigateUri =
           "https://www.devexpress.com/Products/NET/Controls/WinForms/Rich_Editor/"
      hyperlink.ToolTip = "WinForms Rich Text Editor"
  End If
End Using

Note

The hyperlink attached to a shape is not added to the HyperlinkCollection. Check the Shape.Hyperlink property to retrieve the hyperlink.

Remove a Hyperlink

To remove an existing hyperlink, use the HyperlinkCollection.Remove method.

The code sample below locates and removes all hyperlinks in the first section:

C#

using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;

using (var wordProcessor = new RichEditDocumentServer())
{
    // Load a document
    wordProcessor.LoadDocument("Documents//Document.docx");
    Document document = wordProcessor.Document;

    // Obtain all hyperlinks in the first section
    var hyperlinks = document.Hyperlinks.Get(document.Sections[0].Range);
    if (hyperlinks != null)
    {
        // Remove all hyperlinks
        foreach (Hyperlink hyperlink in hyperlinks)
        {
            document.Hyperlinks.Remove(hyperlink);
        }
    }
}

VB.NET

Imports DevExpress.XtraRichEdit
Imports DevExpress.XtraRichEdit.API.Native

Using wordProcessor = New RichEditDocumentServer()
    ' Load a document
    wordProcessor.LoadDocument("Documents//Document.docx")
    Dim document As Document = wordProcessor.Document

    ' Obtain all hyperlinks in the first section
    Dim hyperlinks = document.Hyperlinks.Get(document.Sections(0).Range)
    If hyperlinks IsNot Nothing Then
        ' Remove all hyperlinks
        For Each hyperlink As Hyperlink In hyperlinks
            document.Hyperlinks.Remove(hyperlink)
        Next hyperlink
    End If
End Using
