要在代码中绑定独立编辑器，需要把一个 System.Windows.Forms.Binding 对象添加到控件的 Control.DataBindings 集合中。 System.Windows.Forms.Binding.FormattingEnabled 属性必须被设置为 true。

下面的示例展示了如何把 DateEdit 控件绑定到 Entity 业务对象的一个可空类型的属性。

// An Entity object.
Entity _entity = new Entity();
// Bind the editor to the Entity.NullableDateTime property. 
// Set the Binding.FormattingEnabled property to true.
dateEdit1.DataBindings.Add("EditValue", _entity, "NullableDateTime", true);

public class Entity {
    public Entity() { }

    private DateTime? _nullableDateTime = new DateTime(2001, 1, 1);
    
    public DateTime? NullableDateTime {
        get { return _nullableDateTime; }
        set { _nullableDateTime = value; }
    }
}

' An Entity object.
Dim _entity As Entity = New Entity
' Bind the editor to the Entity.NullableDateTime property. 
' Set the Binding.FormattingEnabled property to true.
Me.DateEdit1.DataBindings.Add(New System.Windows.Forms.Binding( _ 
    "EditValue", _entity, "NullableDateTime", True))

Public Class Entity
    Public Sub New()
    End Sub

    Private _nullableDateTime As Nullable(Of DateTime) = New DateTime(2001, 1, 1)

    Public Property NullableDateTime() As Nullable(Of DateTime)
        Get
            Return _nullableDateTime
        End Get
        Set(ByVal value As Nullable(Of DateTime))
            _nullableDateTime = value
        End Set
    End Property
End Class
