Mass-Update
Setting this property to "1" keeps the isCOBOL framework from repainting the Tree-View control every time the program modifies it. This practice is recommended to increase performance when a large number of changes are applied to the Tree-View control. At the end of the process it is necessary to reset the property to its default value "0" to see the changes.
Example - Load three items in mass update mode
modify screen-1-tv-1 mass-update = 1 modify screen-1-tv-1 parent null, item-to-add "item-1" modify screen-1-tv-1 parent null, item-to-add "item-2" modify screen-1-tv-1 parent null, item-to-add "item-3" modify screen-1-tv-1 mass-update = 0 |
