Use redaction callback Leave feedback
In order to reject or approve specific changes during redaction process or to keep a full log of changes in the document, you need to provide an instance of IRedactionCallback to a constructor of RedactorSettings class. The interface contains only one method, AcceptRedaction(), which receives detailed information about proposed redaction and returns Boolean value, accepted or not.
Below, we create a callback class, dumping changes to system console:
C#
public class RedactionDump : IRedactionCallback
{
public RedactionDump()
{
}
public bool AcceptRedaction(RedactionDescription description)
{
Console.Write("{0} redaction, {1} action, item {2}. ", description.RedactionType, description.ActionType, description.OriginalText);
if (description.Replacement != null)
{
Console.Write("Text {0} is replaced with {1}. ", description.Replacement.OriginalText, description.Replacement.Replacement);
}
Console.WriteLine();
// you can return "false" here to prevent particular change during redaction process
return true;
}
}
The instance of this class is to be passed to a constructor of the Redactor class:
C#
using (Redactor redactor = new Redactor("\\Sample.docx", new LoadOptions(), new RedactorSettings(new RedactionDump())))
{
// Assign an instance before using Redactor
redactor.Apply(new ExactPhraseRedaction("John Doe", new ReplacementOptions("[personal]")));
redactor.Save();
}
You may easily run the code above and see the feature in action in our GitHub examples:
