DataItem triggers
Each DataItem has the following triggers available:
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 these three triggers.
- OnPreDataItem() 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() is the data "read + process loop". The code 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 DataItem Processing Loop.
- OnPostDataItem() executes after all the records in this DataItem are processed, unless the report is terminated by means of...
