For example the Bold, Italic, Underline and Strike-trough commands are not accepted by invoking the AcceptTrackChanges() method. After the post back, the track changes stylization is still the same and the attributes set from the feature (cite, author, timestamp etc.) are not stripped. A possible workaround is using the corresponding method via the Client-side API. To do that you can use this example JavaScript method: function acceptAllChanges() { var editor = $find("<%= RadEditor1.ClientID %>"); var trackChanges = Telerik.Web.UI.Editor.TrackChanges; trackChanges.initialize(editor); trackChanges.acceptAllChangesSilently(); } Note that you should get the correct editor object and pass it as an argument in the initialize() method's overload.
