Determines how to handle a change of the document that cannot be added to the list of tracked changes. Complex table layout changes, such as deleting a table column or merging table cells cannot be tracked. The default handling shows a MessageBox asking the end-user whether the change of the document should be performed. The event handler receives an argument of type CannotTrackChangeEventArgs containing data related to this event. Using the CannotTrackChangeEventArgs.Handled and the CannotTrackChangeEventArgs.Cancel property the default handling can be changed.
