我有下面的xaml,我试图绑定到我的课程。我无法使值显示出来。任何人都可以向我指出我失踪的方向。先谢谢你。Xaml数据绑定
Dim frm As New EditPart
frm.DataContext = New SelectedPart(_CPPartPicker.Selected_Part, "ABC")
frm.Show()
Class SelectedPart
Property Part_Key As Integer
Property Part_Id As String
Property Part_Rev As String
Property Whse As String
Property Part_Description As String
Sub New(Part As SNC.SL.Common.CP_Item.CP_Item_Lookup_Version_1Item_Lookup_Response, Whse As String)
Part_Key = Part.ITEM_KEY
Part_Id = Part.ITEM_ID
Part_Rev = Part.ITEM_RVSN_ID
Whse = Whse
Part_Description = Part.ITEM_DESC
End Sub

在输出中窗口我得到的下面的错误消息:
