Binding System.ArgumentException:';无法绑定到属性';价值';论目标控制

Binding System.ArgumentException:';无法绑定到属性';价值';论目标控制,binding,user-controls,Binding,User Controls,我开发了light UserControl,其中的一些属性支持这样的绑定 public class EditDateTimeBox : UserControl,IKeyboardNavigation { private TextBox textBox; private MonthCalendar monthCalendar = new MonthCalendar(); ToolStripDropDown popup = new ToolStripDropDown();

我开发了light UserControl,其中的一些属性支持这样的绑定

public class EditDateTimeBox : UserControl,IKeyboardNavigation
{

    private TextBox textBox;

    private MonthCalendar monthCalendar = new MonthCalendar();
    ToolStripDropDown popup = new ToolStripDropDown();
    ToolStripControlHost host;
   //.....
   [Bindable(true)]
    public DateTime Value{get;set;}
 }
但当我试着这样捆绑它时:

    bool _binded = false;
    string _dataColumn ;
    [Category("OverB")]
    [Browsable(true)]
    public string DataColumn
    {
        get
        {
            return _dataColumn;

        }
        set
        {
            _dataColumn = value;
            if (!_binded && !string.IsNullOrEmpty(_dataColumn) && _dataSource != null)
            {
                this.DataBindings.Add("Value", DataSource, _dataColumn,true);
                _binded = true;
            }
        }
    }
抛出一个错误,例如: System.ArgumentException:'无法绑定到目标控件上的属性'Value'

当我使用dotnet支持进行调试时,我发现ChechBinding()方法中的绑定类(System.Windows.Forms)导致了这个问题 下面是带有注释的代码

// If the control is being inherited, then get the properties for
            // the control's type rather than for the control itself.  Getting
            // properties for the control will merge the control's properties with
            // those of its designer.  Normally we want that, but for 
            // inherited controls we don't because an inherited control should 
            // "act" like a runtime control.
            //
            InheritanceAttribute attr = (InheritanceAttribute)TypeDescriptor.GetAttributes(control)[typeof(InheritanceAttribute)];
            if (attr != null && attr.InheritanceLevel != InheritanceLevel.NotInherited) {
                propInfos = TypeDescriptor.GetProperties(controlClass);
            }
            else {
                propInfos = TypeDescriptor.GetProperties(control);
            }

            for (int i = 0; i < propInfos.Count; i++) {
                if(tempPropInfo==null && String.Equals (propInfos[i].Name, propertyName, StringComparison.OrdinalIgnoreCase)) {
                    tempPropInfo = propInfos[i];
                    if (tempPropIsNullInfo != null)
                        break;
                }
                if(tempPropIsNullInfo == null && String.Equals (propInfos[i].Name, propertyNameIsNull, StringComparison.OrdinalIgnoreCase)) {
                    tempPropIsNullInfo = propInfos[i];
                    if (tempPropInfo != null)
                        break;
                }
            }

            if (tempPropInfo == null) {
                throw new ArgumentException(SR.GetString(SR.ListBindingBindProperty, propertyName), "PropertyName");
//如果控件被继承,则获取
//控件的类型,而不是控件本身。得到
//控件的属性将控件的属性与
//它的设计者。正常情况下,我们希望这样,但为了
//我们不需要继承控件,因为继承控件应该
//像运行时控件一样“操作”。
//
InheritanceAttribute attr=(InheritanceAttribute)TypeDescriptor.GetAttributes(控件)[typeof(InheritanceAttribute)];
if(attr!=null&&attr.InheritanceLevel!=InheritanceLevel.NotInherited){
PropInfo=TypeDescriptor.GetProperties(controlClass);
}
否则{
PropInfo=TypeDescriptor.GetProperties(控件);
}
for(int i=0;i

有什么想法吗?

对不起,我发现了问题,错误完全是我的,这是僵尸代码

public new controlbindings集合数据绑定{get{return textBox.DataBindings;}}

抱歉

在方法(dotnet)CheckBinding()中,有一些从我的控件到IBindableComponent的转换,因此,我的新属性不存在!…私有IBindableComponent控件;PropInfo=TypeDescriptor.GetProperties(控件);有什么想法吗!!!!
