Allows you to modify the report download target in the Report Viewer dialog or prevent users from downloading a report.

Declaration

property OnExport: TdxReportExportEvent read; write;

Remarks

Handle the OnExport event to execute custom code in response to a report download operation, modify the preview download target, replace the built-in Save As dialog, or prevent the operation depending on specific conditions in your application.
