public event MailMergeRecordStartedEventHandler MailMergeRecordStarted
Public Event MailMergeRecordStarted As MailMergeRecordStartedEventHandler
The MailMergeRecordStarted event's data class is MailMergeRecordStartedEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs. |
| Document | Gets a merged document. |
| MailMergeRegionInfo | Obtains information on the currently merged region. |
| RecordDocument | Gets a template document before a record is merged. |
| RecordIndex | Gets an index of a record currently merged. |
The MailMergeRecordStarted event can be used to pre-process the merged section of a document that corresponds to a particular record.
The code sample below shows how to handle the MailMergeRecordStarted and MailMergeRecordFinished events to insert additional content to the document:
