Assembly: DevExpress.XtraReports.v23.2.dll

Related API Members

DesignerLoadedEventArgs is the data class for the following events:

• XRDesignMdiController.DesignPanelLoaded
• XRDesignPanel.DesignerHostLoaded
• XtraReport.DesignerLoaded

Remarks

The XtraReport.DesignerLoaded and XRDesignPanel.DesignerHostLoaded events occur after any report has been loaded into the End-User Designer. The DesignerLoadedEventArgs class introduces the DesignerLoadedEventArgs.DesignerHost property that specifies the designer host, which provides all the services used when editing a report.

Note

DesignerLoadedEventArgs objects are automatically created, initialized and passed to the XtraReport.DesignerLoaded or XRDesignPanel.DesignerHostLoaded event handler.

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.

See Use Custom Controls to learn how to create custom report controls and add them to a Report Designer’s toolbox.

C#

using DevExpress.XtraReports.UI;
using DevExpress.XtraReports.UserDesigner;
using System.Drawing.Design;
// ...

private void button1_Click(object sender, System.EventArgs e) {
    XtraReport1 report = new XtraReport1();
    ReportDesignTool designTool = new ReportDesignTool(report);
    report.DesignerLoaded += report_DesignerLoaded;
    designTool.ShowRibbonDesignerDialog();
}

void report_DesignerLoaded(object sender, DesignerLoadedEventArgs e) {
    // Access the Toolbox service.
    IToolboxService toolboxService = 
        (IToolboxService)e.DesignerHost.GetService(typeof(IToolboxService));

    // Add a custom control to the default category.
    toolboxService.AddToolboxItem(new ToolboxItem(typeof(XRZipCode)));

    // Add a custom control to a new category.
    // toolboxService.AddToolboxItem(new ToolboxItem(typeof(XRZipCode)), "New Category");
}
