Similar to the report element itself, the Grid control contains LoadGridInit and LoadGridNext print events. You name and code these paragraphs using the steps described Adding Report and Report Element Events. The code in these paragraphs is used to initialize and READ data into your Grid control.
For example, you might define a LoadGridInit paragraph similar to this:
Myreport-LoadGridInit. move low-values to sales-key start sales key >= sales-key read sales-key next at end move 0 to myreport-mygrid-LOADGD-SW end-read .
And a LoadGridNext paragraph similar to this:
Myreport-LoadGridNext. read sales-key next at end move 0 to myreport-mygrid-LOADGD-SW end-read .
The same advantages of using the events described in BeforeDoPrint and AfterDoPrint Event Paragraphs, apply to these events as well.
