我編寫了一個類,並希望它的屬性在DataGridView控件中顯示。但是,只有一些屬性可用於綁定到列。我如何使所有公共屬性都可以綁定到列?以下是我的課程,IndividualServices屬性沒有出現在設計師中,而其他人則是。將自定義類的屬性綁定到WinForms DataGridView
Public Class Patient
Private _name As String
Private _id As String
Private _services As New List(Of Service)
Property Name As String
Get
Return _name
End Get
Set(value As String)
_name = value
End Set
End Property
Property ID As String
Get
Return _id
End Get
Set(value As String)
_id = value
End Set
End Property
Public ReadOnly Property Services As List(Of Service)
Get
Return _services
End Get
End Property
ReadOnly Property TotalServices As Integer
Get
Dim i As Integer = 0
For Each s As Service In _services
i = i + s.Count
Next s
Return i
End Get
End Property
ReadOnly Property IndividualServices As Integer
Get
Return _services.Count
End Get
End Property
Public Sub Add(sName As String, sCode As String)
Dim bool As Boolean = False
If _services.Count = 0 Then GoTo firstThrough
For Each s As Service In _services
If s.Name = sName Then
s.Add(1)
bool = True
Exit For
End If
Next
If Not bool Then
firstThrough:
Dim newSer As New Service
newSer.Name = sName
newSer.Code = sCode
newSer.Count = 1
_services.Add(newSer)
End If
End Sub
End Class
你到目前爲止嘗試過的所有東西?你有沒有試過返回「_services.Count」而不是「Services.Count」? – Andarta
設計師沒有改變,但感謝您指出了這一點!進行編輯。我將它添加爲僅用於DataGridView的屬性,否則我一直在調用Patient.Services.Count – aitchpat
Off-Topic,但強烈建議:避免使用「GoTo」語句。 –
