绑定到 List 时 DataTextField 不起作用

Question

Public Class Item

    Public Text As String
    Public Value As Integer

End Class

Me.uxDropDown.DataSource = itms
Me.uxDropDown.DataTextField = "Text"
Me.uxDropDown.DataValueField = "Value"
Me.uxDropDown.DataBind()

为什么这不起作用，itms 是 List(Of Item)？

上线触发错误事件：Me.uxDropDown.DataBind()

DataBinding：“Project.Item”不包含名为“Text”的属性。

Answer 1

错误显然是“DataBinding：‘Item’不包含名为‘Text’的属性。”将这些公共变量改为公共属性，您的错误就会消失。

Public Class Item
    Private _Text As String
    Private _Value As Integer

    Public Property Text() As String
        Get
            Return _Text
        End Get
        Set(ByVal value As String)
            _Text = value
        End Set
    End Property

    Public Property Value() As Integer
        Get
            Return _Value
        End Get
        Set(ByVal value As Integer)
            _Value = value
        End Set
    End Property
End Class
