The Standalone Report Parameters Panel is a component that creates a layout with editors for report parameters. It retrieves information on report parameters from a DevExpress report instance passed from the backend.
Use this component to programmatically create a report, then export or email it without showing a preview to the end user. The component reduces memory usage by eliminating the need to generate report preview and sending it to the client application.
The Standalone Report Parameters Panel component is based on the Parameters Panel of the DevExpress Web Report Viewer component. Public properties and events are similar to the properties and events implemented in the Web Document Viewer component.
