The History property indicates whether or not to enable the toolbar history (ditto) button for this ToolbarUpdateClass object. The ToolbarUpdateClass uses this value to set the appropriate toolbar button TIP attribute and enable or disable the appropriate toolbar button.
By convention the history button restores the previous value for a field or record. See Control Templates–SaveButton for more information.
Implementation:
The TakeToolbar and DisplayButtons methods set the toolbar state based on the value of the History property. A History value of one (1) enables the toolbar history button; a value of zero (0) disables the history button
