C#-Windows窗体用户控件，带有子控件和数据绑定

我创建了一个相当简单的用户控件，其中包含一些子控件和组件。我在一个components属性和一个controls属性之间添加了一个数据绑定。到目前为止，当我将用户控件添加到表单时，问题就出现了。VisualStudio序列化程序在InitializeComponent方法中再次添加该绑定，因此引发异常，告诉我该属性已进行数据绑定

另一个小问题是，它还序列化了我在用户控件本身中更改的属性，即使我没有在表单中更改它们。这个问题可能导致上述问题，我真的不知道

用户控制代码：

public partial class BrowseFolder : UserControl {
    private const string CATEGORY_CONTROLS = "Controls";

    public BrowseFolder() {
        InitializeComponent();
    }

    [Category(CATEGORY_CONTROLS)]
    [Description("The label that describes the folder's meaning in the context it's in.")]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
    public Label Label => this.Lbl;
    [Category(CATEGORY_CONTROLS)]
    [Description("The text box that displays or lets the user edit the full path of the folder.")]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
    public TextBox TextBox_DirectoryFullPath => this.TxtBox_DirectoryFullPath;
    [Category(CATEGORY_CONTROLS)]
    [Description("The button that displays the folder browse dialog when clicked.")]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
    public Button Button_BrowseDirectory => this.Btn_BrowseDirectory;
    [Category(CATEGORY_CONTROLS)]
    [Description("The folder browse dialog.")]
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
    public NotifyPropertyChangedFolderBrowseDialog FolderBrowserDialog => this.Fbd;

    private void Btn_BrowseDirectory_Click(object sender, EventArgs e) =>

        this.Lbl.TabIndex = 8;
        this.Lbl.Text = "Text:";

        //

正在引发的异常：

您已使用以下内容装饰您的

文本框

：

[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public TextBox SomeTextBox { get { return someTextBox; } }

这意味着

SomeTextBox

的所有属性的值与默认值不同，将被序列化

要解决有关

数据绑定的问题，防止将其序列化为表单，请在用户控件中添加数据绑定（如果控件未处于设计模式）：

if(LicenseManager.UsageMode != LicenseUsageMode.Designtime)
    someTextBox.DataBindings.Add("Text", SomeOtherControl, "SomeProperty", true);

不了解控件的详细内容，但如果要更改到另一个源的绑定，可以调用
control.DataBindings.Clear（）
删除所有绑定，然后添加新的bindingsource。非常感谢，顺便说一句，我很好奇LicenseManager类是什么。不客气。我用它来检测控件是否处于设计模式<代码>设计模式

属性在控件的构造函数中不起作用，所以我使用了。你会发现这很有用。
