FetchData Event
See Also  Example
GrapeCity.ActiveReports.v7 Assembly > GrapeCity.ActiveReports Namespace > SectionReport Class : FetchData Event

Glossary Item Box

Raised every time a new record is processed.

Syntax

Visual Basic (Declaration) 
Public Event FetchData As SectionReport.FetchEventHandler
C# 
public event SectionReport.FetchEventHandler FetchData

Event Data

The event handler receives an argument of type SectionReport.FetchEventArgs containing data related to this event. The following SectionReport.FetchEventArgs properties provide information specific to this event.

PropertyDescription
EOF

This parameter is passed by reference and its default Value is True.  It has to be explicitly set to False for the report to continue processing more records when the report is unbound. For bound reports, the EOF property is set automatically.

Remarks

This event is used to set the values of custom unbound fields that were added in the DataInitialize event.

ActiveReports does not null unbound field values before firing this event.  The unbound field value is carried over so you should always set the values of all unbound fields in this event.

Note:  Do not reference the Fields collection outside the DataInitialize and FetchData events.
