XRDesignMdiController.DesignPanelLoaded Event

Occurs when the End-User Designer loads a report and loads a new XRDesignPanel for that report.

Namespace: DevExpress.XtraReports.UserDesigner

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

NuGet Package: DevExpress.Win.Reporting

Declaration

C#

public event DesignerLoadedEventHandler DesignPanelLoaded

VB.NET

Public Event DesignPanelLoaded As DesignerLoadedEventHandler

Event Data

The DesignPanelLoaded 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

Handle the DesignPanelLoaded event to customize the End-User Designer UI after a report is loaded. For code samples, review the following help topics:

• Execute Commands in the End-User Report Designer
• Override Commands in the End-User Report Designer (Implement Custom Saving)
• Make a Custom Control Available Only for a Specific Report
• Rename Toolbox Items in the End-User Report Designer
• Customize the Properties Window in the End-User Report Designer
• Bind a Report to a Microsoft SQL Server Database at Runtime

The DesignPanelLoaded event in a multi-document interface is similar to the XtraReport.DesignerLoaded event that occurs in a single-document Report Designer version, but changes are applied to all reports opened within the End-User Report Designer form.

Example

This example illustrates how to add a custom control to an End-User Report Designer’s toolbox by handling the XRDesignMdiController.DesignPanelLoaded event and accessing 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) {
    // Create a Design Tool with an assigned report instance.
    ReportDesignTool designTool = new ReportDesignTool(new XtraReport1());

    // Access the standard or ribbon-based Designer form.
    // IDesignForm designForm = designTool.DesignForm;
    IDesignForm designForm = designTool.DesignRibbonForm;

    // Handle the Design Panel's Loaded event.
    designForm.DesignMdiController.DesignPanelLoaded += DesignMdiController_DesignPanelLoaded;

    // Load a Report Designer in a dialog window.
    // designTool.ShowDesignerDialog();
    designTool.ShowRibbonDesignerDialog();
}

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

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

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