set_screen_update

Use this method to control whether the tree is refreshed. Use the UPDATE parameter to determine whether changes to the tree control should be visible immediately.

Use this method if the tree control is redrawn too many times in quick succession due to a series of changes to the data.

Using it will improve the performance of your program. Call it at the beginning of the PAI event using UPDATE = ' ' and then again at the end of the PBO event using UPDATE = 'X'.
