Question

由于System.Windows.Forms的形式继承自Control，我想知道是否有办法创建自定义表单及其设计器，其中包含一些选项（快捷方式）来创建标题或类似的标题。

我试过这个，但没有发生，表格I调用ManagedForm

[Designer(typeof(ManagedFormDesigner))]
public class ManagedForm : Form{
   //code here
}


[PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name = "FullTrust")] 
public class ManagedFormDesigner : ControlDesigner {
    private DesignerActionListCollection actionLists;
    public override DesignerActionListCollection ActionLists {
        get {
            if (actionLists == null) {
                actionLists = new DesignerActionListCollection();
                actionLists.Add(new ManagedFormDesignerActionList(this.Component));
            }
            return actionLists;
        }
     }
}



public class ManagedFormDesignerActionList : DesignerActionList {
    private ManagedForm managedForm = null;
    private DesignerActionUIService designerActionUISvc = null;

    public ManagedFormDesignerActionList(IComponent component) : base(component) {
        this.managedForm = component as ManagedForm;
        this.designerActionUISvc =
        GetService(typeof(DesignerActionUIService))
        as DesignerActionUIService;
    }

    public override DesignerActionItemCollection GetSortedActionItems() {
        DesignerActionItemCollection items = new DesignerActionItemCollection();
        items.Add(new DesignerActionMethodItem(this, "CreateTitle", "Create Title", "Appearence", true));
        return items;
    }

    public void CreateTitle() {
        Panel pTitulo = new Panel();
        pTitulo.Size= new Size(100,25);
        pTitulo.Dock = DockStyle.Top;
        (this.Component as ManagedForm).Controls.Add(pTitulo);
    }

}

当您单击窗体内控件上的小箭头时（或者如果对象是组件，则位于设计器底部的组件上），将显示操作列表。

您可以做的其他事情是管理动词。动词处理是在ControlDesigner类（在您的情况下为ManagedFormDesigner）上实现的。你可以看到动词点击鼠标右键或属性的底部（即TabControl ha 2动词，添加标签和删除标签）。

您可以实现添加到ControlDesigner（或ComponentDesigner）类的动词类似

    private DesignerVerbCollection _verbs;

    public override DesignerVerbCollection Verbs
    {
        get
        {
            if (_verbs == null)
            {
                _verbs = new DesignerVerbCollection();
                _verbs.Add(new DesignerVerb("Create Title", new EventHandler(MyCreateTitleHandler)));
            }
            return _verbs;
        }
    }

    private void MyCreateTitleHandler(object sender, EventArgs e)
    {
        // Do here something but take care to show things via IUIService service
        IUIService uiService = GetService(typeof(IUIService)) as IUIService;
    }

使用c＃为表单（而不是其他控件）创建智能标记
