C# UserControl未更新到表

问题

只有当我尝试插入时，问题才会出现。但是我可以浏览记录。当我插入一个新的记录时，USER控件不考虑我键入的值，而是将它存储为NULL。我基本上认为在新唱片上，它不同步

表单布局

用户控制的目的

DB以JKB-932340094VN00的形式存储字段值，我使用我的UserControl按-分割值，并在其中的2个文本框中显示它。因此，一个文本框的值为JKB，另一个文本框的值为932340094VN00

UserControl如下所示：

public partial class ucClientAccountIDParser : UserControl, INotifyPropertyChanged
{
    public ucClientAccountIDParser()
    {
        InitializeComponent();
        id = "JKB-821230063VN00";

        txtClientAccountID.TextChanged += new EventHandler(clientaccountIDChanged);
        txtCustodyID.TextChanged += new EventHandler(custodyIDChanged);
    }

    private string _clientaccountID = string.Empty;

    public string ClientaccountID
    {
        get { return _clientaccountID; }
        set 
        { 
            _clientaccountID = value;
            txtClientAccountID.Text = this._clientaccountID;
        }
    }
    private string _custodyID = string.Empty;

    public string CustodyID
    {
        get { return _custodyID; }
        set 
        { 
            _custodyID = value;
            txtCustodyID.Text = this._custodyID;
        }
    }

    #region INotifyPropertyChanged Members

    public event PropertyChangedEventHandler PropertyChanged;

    #endregion

    public string id = string.Empty;

    [System.ComponentModel.Bindable(true)]
    public string Text
    {
        get
        {
            return id;
        }
        set
        {
            id = value;

            if (id != null)
            {
                string[] aVal = id.Split('-');

                if (aVal.Length > 1)
                {
                    this.CustodyID = aVal[0];
                    this.ClientaccountID = aVal[1];
                }
                else
                {
                    this.ClientaccountID = id;
                }
            }
            else
            {
                this.CustodyID = string.Empty;
                this.ClientaccountID = string.Empty;   
            }

            NotifyPropertyChanged(id);
        }
    }

    public void NotifyPropertyChanged(string info)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs("Text"));
        }
    }

    private void clientaccountIDChanged(object sender, EventArgs e)
    {
        this.id = string.Format("{0}-{1}", txtCustodyID.Text, (sender as TextBox).Text);
        NotifyPropertyChanged(this.id);
    }

    private void custodyIDChanged(object sender, EventArgs e)
    {
        this.id = string.Format("{0}-{1}", (sender as TextBox).Text, txtClientAccountID.Text);
        NotifyPropertyChanged(this.id);
    } 
}

我是这样绑定它的：

我不明白为什么需要空值。让我知道我是否以正确的方式进行了UserControl的设计

我希望任何人都能帮助我。

保存操作的代码在哪里？这可能是问题所在。是的，我修改了UserControl中的一些内容，效果很好。作为一个结果，我有了新的插曲，所以打开了一个新的帖子。我能够从中提取代码。再次感谢！如果你的问题解决了，你可以删除帖子。

try
            {
                this.Init(null);
                this.Text = "General Account Add/Change";

                objTable = new ClientAccountBusinessTable();
                this.PrimaryDataAdapters = new ClientAccountBusinessTable[1] { objTable };
                this.PrimaryDataGridView = null;

                objTable.KeyDBField = "CLIENTID";
                PrimaryBindingSource = new BindingSource[1] { bindingSource1 };
                PrimaryDataSet.Tables.Add(objTable.GetBusinessTable());

                SetKeyDBControl(new Control[1] { ucClientAccountIDParser1 }, new string[1] { "CLIENTID" });

                ucClientAccountIDParser1.DataBindings.Clear();
                ucClientAccountIDParser1.DataBindings.Add(new Binding("Text", this.bindingSource1, "CLIENTID"));

                bindingSource1.DataMember = this.PrimaryDataSet.Tables[0].TableName;
                bindingSource1.DataSource = this.PrimaryDataSet;
            }
            catch (Exception ex)
            {
                objTable = null;
                throw ex;
            }
