Question

我创建了一个新的自定义控件，继承自Bar control个DevComponents.DotNetBar个控件。接下来，我在其中创建了一个新的dock选项卡，并将其他控件添加到其中。

编译自定义控件并在新的Windows窗体中添加创建的自定义控件后，Dock选项卡控件在设计时可编辑。

我不希望任何人在设计时编辑这些控件（Dock Tab Controls）。如何在设计时禁止从表单编辑控件（与编辑控件本身不同）？

Answer 1

您必须使用 ParentControlDesigner 类扩展设计模式行为。 ParentControlDesigner类为可以包含子控件的控件的设计者提供基类。

因此，要实现目标，您必须通过 DesignerAttribute 实现组件的设计时服务，如下所示（只需在编写的类之前添加以下代码）：

[Designer("System.Windows.Forms.Design.ParentControlDesigner, System.Design", typeof(IDesigner))]
public partial class barFloorsGrouping : Bar
{
...
}

编辑：一如既往，我在asp.net和webforms工作......这个答案适用于WebForms

您需要覆盖WebControl的GetDesignTimeHtml。

请参阅MSDN docs

听起来我没有做过很多服务器控件创建，所以你可以获得很多乐趣......
