Table Update - GRID Notify Event 22 BBj


For this topic's original documentation, see Table Update - GRID Notify Event 22.

BBj-Specific Information

  • In BBj, the grid stores the cell data internally, and it is no longer necessary to maintain an external data source. Because of this, the Table Update Notify Event behaves differently than in Visual PRO/5.

  • A table update event is generated when the grid is displayed on the screen for the first time. An update for all cells is requested at this time. When the number of rows or columns increases, a table update event is generated for the added rows and columns. When the number of rows or columns decreases, an update event is generated for any rows or columns with a higher index value than the removed rows or columns.

  • For backward compatibility, an update event is also generated when the user scrolls the grid for the newly displayed rows and columns. Responding to all the update events is no longer necessary.

  • It is recommended that all grid data be set using Set Multiple Cells - GRID SENDMSG() Function 21, and default styles be set using Draw Cell - GRID SENDMSG() Function 54 during grid initialization.
