Accepting or Rejecting Track Changes

5 Sep 202417 minutes to read

It is used to keep track of the changes made to a Word document. It helps to maintain the record of author, name and time for every insertion, deletion, or modification in a document. This can be enabled by using the TrackChanges property of the Word document.

NOTE

With this support, the changes made in the Word document by DocIO library cannot be tracked.

The following code example illustrates how to enable track changes of the document.

NOTE

Refer to the appropriate tabs in the code snippets section: C# [Cross-platform] for ASP.NET Core, Blazor, Xamarin, UWP, .NET MAUI, and WinUI; C# [Windows-specific] for WinForms and WPF; VB.NET [Windows-specific] for VB.NET applications.

C# [Cross-platform]

//Creates a new Word document 
WordDocument document = new WordDocument();
//Adds new section to the document
IWSection section = document.AddSection();
//Adds new paragraph to the section
IWParagraph paragraph = section.AddParagraph();
//Appends text to the paragraph
IWTextRange text = paragraph.AppendText("This sample illustrates how to track the changes made to the word document. ");
//Sets font name and size for text
text.CharacterFormat.FontName = "Times New Roman";
text.CharacterFormat.FontSize = 14;
text = paragraph.AppendText("This track changes is useful in shared environment.");
text.CharacterFormat.FontSize = 12;
//Turns on the track changes option
document.TrackChanges = true;
//Saves the Word document to  MemoryStream
MemoryStream stream = new MemoryStream();
document.Save(stream, FormatType.Docx);
//Closes the document
document.Close();

Accept all changes

You can accept all track changes in Word document using AcceptAll method.

The following code example shows how to accept all the tracked changes.

C# [Cross-platform]

//Opens an existing Word document
FileStream fileStreamPath = new FileStream("Template.docx", FileMode.Open, FileAccess.Read, FileShare.ReadWrite);           
WordDocument document = new WordDocument(fileStreamPath, FormatType.Docx);
//Accepts all the tracked changes revisions in the Word document
if (document.HasChanges)
    document.Revisions.AcceptAll();
//Saves the Word document to MemoryStream
MemoryStream stream = new MemoryStream();
document.Save(stream, FormatType.Docx);
//Closes the document
document.Close();

C# [Windows-specific]

//Opens an existing Word document
WordDocument document = new WordDocument("Template.docx", FormatType.Docx);
//Accepts all the tracked changes revisions
if (document.HasChanges)
    document.Revisions.AcceptAll();
//Saves and closes the document
document.Save("Sample.docx", FormatType.Docx);
document.Close();

VB.NET [Windows-specific]

'Opens an existing Word document
Dim document As WordDocument = New WordDocument("Template.docx", FormatType.Docx)
'Accepts all the tracked changes revisions
If document.HasChanges Then
    document.Revisions.AcceptAll()
End If
'Saves and closes the document
document.Save("Sample.docx", FormatType.Docx)
document.Close()
System.Diagnostics.Process.Start("Sample.docx")

//Iterates into all the revisions in Word document
for (int i = document.Revisions.Count - 1; i >= 0; i--)
{
    //Checks the author of current revision and accepts it.
    if (document.Revisions[i].Author == "Nancy Davolio")
        document.Revisions[i].Accept();
    //Resets to last item when accept the moving related revisions.
    if (i > document.Revisions.Count - 1)

}
//Saves the Word document to MemoryStream
MemoryStream stream = new MemoryStream();
document.Save(stream, FormatType.Docx);

Revision revision = document.Revisions[0];
//Gets the name of the user who made the specified tracked change
string author = revision.Author;
// Gets the date and time that the tracked change was made
DateTime dateTime = revision.Date;
// Gets the type of the track changes revision
RevisionType revisionType = revision.RevisionType;
//Closes the document
document.Close();
