Each DataItem has the following triggers available:
The DataItem triggers are where most of the flow logic is placed for a report. Developer defined functions may be freely added but, generally, they will be called from within the following three triggers:
- OnPreDataItem(): This is the logical place for any preprocessing to take place that can't be handled in report or DataItem properties or in the two report preprocessing triggers.
- OnAfterGetRecord(): This is the data read and process loop. The code that's placed here has full access to the data of each record, one record at a time. This trigger is repetitively processed until the logical end of table is reached for this DataItem. This is where we would typically access data in related tables. This trigger is represented on our report data flow diagram as any one of the boxes labeled Data Item processing Loop.
- OnPostDataItem(): This executes after all the records in this DataItem are processed,...
