Since version X16, TX Text Control provides a way to track changes in documents made by multiple authors to enable document collaboration.

In order to accept or reject a tracked change, the specific change needs to be removed from the

>TXText Control. Tracked Change Collection. Remove method .

Sometimes, it is required to remove all changes from the whole document by a given Username . For this purpose, we implemented two extension methods. Extension methods enable you to add additional functionality to existing classes.

The following extension methods remove all changes from the TrackedChangeCollection or all changes from all TextParts :

namespace TrackedChangeCollectionExtensions { public static class TrackedChangeCollectionExtensions { // removes all changes in the TrackedChangeCollection with a given username public static int RemoveAll( this TXTextControl.TrackedChangeCollection trackdChangeCollection, string username, bool accept) { List myTrackedChanges = new List ();

// loop through all changes foreach (TXTextControl.TrackedChange trackedChange in trackdChangeCollection) { if (trackedChange.UserName == username) myTrackedChanges.Add(trackedChange); }

// delete all changes foreach (TrackedChange listedTrackedChange in myTrackedChanges) trackdChangeCollection.Remove(listedTrackedChange, true);

return myTrackedChanges.Count; }

// removes all changes in all TextParts with a given username public static int RemoveAllTrackedChanges( this TXTextControl.TextPartCollection textPartCollection, string username, bool accept) { // counter var deletedTrackedChanges = 0;

// loop through all text parts foreach (IFormattedText textPart in textPartCollection) { List myTrackedChanges = new List ();

// loop through all changes foreach (TXTextControl.TrackedChange trackedChange in textPart.TrackedChanges) { if (trackedChange.UserName == username) myTrackedChanges.Add(trackedChange); }

// delete all changes foreach (TrackedChange listedTrackedChange in myTrackedChanges) { textPart.TrackedChanges.Remove(listedTrackedChange, true); deletedTrackedChanges++; } }

return deletedTrackedChanges; } } } In order to accept all changes made by the user development@devteam.com , only the following call is required:

var removedChanges = textControl1.TrackedChanges.RemoveAll("development@devteam.com", true); If you need to reject all changed in all text parts including the header, footer, main text and text frames, the following call can be used:

var removedChanges = textControl1.TextParts.RemoveAllTrackedChanges("development@devteam.com", false); If you did not try version X16 already, please download a trial version and test this on your own.
