Namespace: DevExpress.XtraReports.UserDesigner

Assembly: DevExpress.XtraReports.v24.2.Extensions.dll

NuGet Package: DevExpress.Win.Reporting

Declaration

public event DesignerLoadedEventHandler DesignerHostLoaded

Event Data

The DesignerHostLoaded event's data class is DesignerLoadedEventArgs. The following properties provide information specific to this event:

Property Description
DesignerHost Gets the designer host which provides all the services that are available for editing a report in its End-User Designer.

Remarks

Use the DesignerHostLoaded event, to perform particular actions (for instance, customize the designer’s Toolbox), after all initialization has been performed (all the hosts and services required by the End-User Designer have been initialized) and the Designer is ready to be shown.

Example

This example adds a custom control to the toolbox in the End-User Report Designer for Winforms. The XtraReport.DesignerLoaded event is used to access the toolbox service.

Tip

This code adds the XRZipCode control to the toolbox. It is hidden by default because most countries do not use it.
