Winform user control does not create designer code after user's edit?WinForm自定义控件编辑结果不在窗体代码生成？

我创建了一个名称为MSTagServer的自定义控件，其中有个属性为SavedTagsList，给用户提供弹出窗体编辑需要确认的勾选项。为了能记住用户的勾选项，我想再窗体代码内进行生成，问题是编辑完毕后，窗体代码没有任何的变化。测试过程中，我发现只要移除[Editor(typeof(SavedTagSelectDropDownEditor)这段属性代码，用VS标准的方式编辑，每次关闭，均能在设计器中产生代码记忆编辑内容，但是为何用自定义的编辑窗体就不行呢？

I create a user control named MSTagServer.the control have a property named SavedTagsList which show user the UITypeEditor window to check saved tags.the problem is the desiger does not generate any code like
this.msTagServer1.SavedTagsList.Add(((Advantech.MSControl.SavedTag)(resources.GetObject("msTagServer1.SavedTagsList"))));if I remove the line [Editor(typeof(SavedTagSelectDropDownEditor), typeof(UITypeEditor))],the vs will generate designer codeas soon as the edit windown close.so,what's the problem?why the user's UITypeEditor can not trigger the form deigner?控件代码
public partial class MSTagServer : Component private List<SavedTag> _list = new List<SavedTag>(); [Editor(typeof(SavedTagSelectDropDownEditor), typeof(UITypeEditor))] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public List<SavedTag> SavedTagsList { set { _list = value; if (_list != null && Common.EditEnvironmentCheck() == false)//not edit mode,mark { if (TagList.TagsDic.Count > 0) { foreach (SavedTag item in _list) { TagGroup grp = TagList.TagsDic[item.TagGroupName]; Tag tag = grp.Tags.Find(x => x.TagName.Equals(item.TagName)); tag.SaveToFile = true; } } } } get { return _list; } }
弹出窗体编辑器
public class SavedTagSelectDropDownEditor : System.Drawing.Design.UITypeEditor { public override UITypeEditorEditStyle GetEditStyle(System.ComponentModel.ITypeDescriptorContext context) { if (context != null && context.Instance != null) { return UITypeEditorEditStyle.Modal; } return base.GetEditStyle(context); } public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value) { IWindowsFormsEditorService editorService = null; if (context != null && context.Instance != null && provider != null) { editorService = (IWindowsFormsEditorService)provider.GetService(typeof(IWindowsFormsEditorService)); if (editorService != null) { MSTagServer ts = (MSTagServer)context.Instance; if (ts != null) { FrmTagSelectControl ctrl = new FrmTagSelectControl(ts.TagDic, ts.SavedTagsList); DialogResult res = editorService.ShowDialog(ctrl);//show user's edit window if (res == DialogResult.OK) { value = ctrl.SavedTagsList; return value; } } } } return value; } }
需要存储在设计器中的类
[Serializable] public class SavedTag { public string TagGroupName { set; get; } public string TagName { set; get; } }
