Question

我可以使用此代码将组合框绑定到linq对象的属性（其中salesOrderHeader是我的linq对象，而CustomerId是属性）：

cb_Customer.DataBindings.Add(New Binding("SelectedValue", salesOrderHeader, "CustomerId"))

但是，这仅在属性为整数数据类型时才有效。

当我尝试以下操作时，它无法正常工作，因为＆order.3＆＃39; orderCurrencyid＆＃39;只是一个字节

cb_OrderCurrency.DataBindings.Add(New Binding("SelectedValue", salesOrderHeader, "orderCurrencyid"))

如何将LINQ对象中的非整数值绑定到组合框？

感谢Fabio指出我正确的方向。

我设法通过更改我的组合框项目类来解决这个问题：

Public Class cbValues

    Private mItemId As Integer
    Private mItemName As String

    Public Sub New(ItemId As Integer, ItemName As String)
        mItemId = ItemId
        mItemName = ItemName
    End Sub

    Public Property ItemId As Integer
        Get
            Return mItemId
        End Get
        Set(value As Integer)
            mItemId = value
        End Set
    End Property

    Public Property ItemName As String
        Get
            Return mItemName
        End Get
        Set(value As String)
            mItemName = value
        End Set
    End Property

End Class

要

Public Class cbValues

    Private mItemId As Object
    Private mItemName As String

    Public Sub New(ItemId As Object, ItemName As String)
        mItemId = ItemId
        mItemName = ItemName
    End Sub

    Public Property ItemId As Object
        Get
            Return mItemId
        End Get
        Set(value As Object)
            mItemId = value
        End Set
    End Property

    Public Property ItemName As String
        Get
            Return mItemName
        End Get
        Set(value As String)
            mItemName = value
        End Set
    End Property

End Class

更改对象的所有整数引用，意味着它现在可以工作并绑定，无论ItemId属性的数据类型是什么。
