XtraReports > 示例 > 如何： 隐藏最终用户设计器中的底部组件面板

Note注意

重要说明： .NET Client Profile Framework 不支持此功能。 要在最终用户的机器上使用此功能，则必须安装完整的 .NET Framework。 更多信息，请参阅 Windows 窗体部署 文档中的 关于 .NET Framework 4.0 Client Profile 的重要说明 小节。

这个示例展示了如何隐藏或显示在设计面板底部的组件面板(Tray)。 这样允许对最终用户隐藏有关的数据源和数据适配器对象。

要这样做，则在 XRDesignMdiController.DesignPanelLoaded 事件处理程序中设置 XRDesignPanel.ShowComponentTray 属性。

要使本示例能正确工作，则 XtraReport1 子类(派生于 XtraReport 类) 应该存在于示例应用程序中。

    // Hide the Component Tray from the Design Panel.
    designPanel.ShowComponentTray = false;
