E9.1 Practical Use of the Grid Buffer

[FrankCLT]

Hello All,

Can someone explain the practical use of the Grid Buffer? I know you can write to the buffer, manipulate it, and write it back to the grid (GC), and vice versa. I ask because I've never really had the need to use it.


Thank you,
FrankCLT

You have identified the main use, writing records to the grid. I use it all the time when loading a grid "programmatically", usually from jdeCache.

You can use it to 'squirt' your own grid records in from the first row to the last,
OR
Squirt one in as a summary where ever you want as a level break as records are read in and added to the grid. Summary records, information records, whatever you want really

Header and detail lists all in one grid, you can also use it to set focus

The Grid Buffer in Event Rules is updated immediately, and the Grid Column is updated only after the Event Rules are executed.
If you want to update the values of the fields and immediately use the updated result (for writing to the table, cache or other tasks) Then also use Grd Buffer
