TJvCustomCsvDataSet.OnGetFieldData

Summary
Event fired when field data is going to be provided to a data aware control.

Parameters
Sender - Description for this parameter
UserTag - The record's tag (integer) property
UserData - The record's data (pointer) property. Perhaps this is the custom object that contains the actual data?
FieldName - The field name we are being asked for?
Value - var parameter - This is where you put the actual value (encoded as a CSV string) to be provided to the data aware control.

Description
An OnGetFieldData event written by the end user allows the end user to create a Virtual DataSet where the data in the CSV rows is really just a cache which can be updated when displayed but which we really are fetching from somewhere else.<br>
