Examples

This example illustrates how to access and customize the Report Designer's dock panels.

NOTE

All the Report Designer's dock panels inherit their settings from the DesignDockPanel class which is a DockPanel class descendant.

For this reason, you need to reference the DevExpress.XtraBars.v20.1 library in your application to be able to access the Report Designer's dock panel settings.

using DevExpress.XtraBars.Docking;
using DevExpress.XtraReports.UI;
using DevExpress.XtraReports.UserDesigner;
// ...

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 and its MDI Controller.
    // IDesignForm designForm = designTool.DesignForm;
    IDesignForm designForm = designTool.DesignRibbonForm;

    // Access and hide the Group and Sort panel.
    GroupAndSortDockPanel groupSort =
        (GroupAndSortDockPanel)designForm.DesignDockManager[DesignDockPanelType.GroupAndSort];
    groupSort.Visibility = DockVisibility.AutoHide;

    // Access and hide the Report Explorer.
    ReportExplorerDockPanel reportExplorer =
        (ReportExplorerDockPanel)designForm.DesignDockManager[DesignDockPanelType.ReportExplorer];
    reportExplorer.Visibility = DockVisibility.AutoHide;

    // Access and hide the Report Gallery.
    ReportGalleryDockPanel reportGallery =
        (ReportGalleryDockPanel)designForm.DesignDockManager[DesignDockPanelType.ReportGallery];
    reportGallery.Visibility = DockVisibility.AutoHide;

    // Access the Property Grid and customize some of its settings.
    PropertyGridDockPanel propertyGrid =
        (PropertyGridDockPanel)designForm.DesignDockManager[DesignDockPanelType.PropertyGrid];
    propertyGrid.ShowCategories = false;
    propertyGrid.ShowDescription = false;

    // Access the Field List and customize some of its settings.
    FieldListDockPanel fieldList =
        (FieldListDockPanel)designForm.DesignDockManager[DesignDockPanelType.FieldList];
    fieldList.ShowNodeToolTips = false;
    fieldList.ShowParametersNode = false;

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