Gets or sets a value that indicates whether data source is automatically updated when target GanttChartItem and PredecessorItem objects generated by the converter get their internally bound values changed. Set this property to false when the feature is not needed, e.g. when the user interface is read only (by default it is set to true in order to automatically propagate changes back to the data source as expected in most situations). This property can be set only at initialization time (an exception is thrown if it is set after having the conversion process started).
