我對DatagridComboboxColumn有一個類似的問題,但它告訴我如何使用.itemsource綁定到數據網格之外的數組。我在嘗試綁定到數據網格在運行時綁定的集合時遇到問題。WPF VB.NET 4.0 DatagridComboBoxColumn運行時綁定
我已經包含了一個工作測試程序,用於處理這個問題。
Class MainWindow
Dim ServerInfoArray As List(Of ServerInfo) = New List(Of ServerInfo)
Private Sub GetInfo(ByVal list As List(Of String))
For Each server As String In list
Dim tempip As ComboBoxItem = New ComboBoxItem
Dim tempip2 As ComboBoxItem = New ComboBoxItem
Dim sinfo As ServerInfo = New ServerInfo
tempip.Content = "192.129.123.23"
tempip2.Content = "23.213.223.21"
sinfo.IPArray.Items.Add(tempip)
sinfo.IPArray.Items.Add(tempip2)
sinfo.ServerName = server
ServerInfoArray.Add(sinfo)
DataGrid1.Items.Refresh()
Next
End Sub
Private Sub Button1_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles Button1.Click
Dim serverlist As List(Of String) = New List(Of String)
serverlist.Add("Test")
serverlist.Add("Random")
serverlist.Add("Local")
GetInfo(serverlist)
End Sub
Private Sub Window_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
Dim Col_Serial As DataGridTextColumn = New DataGridTextColumn()
Col_Serial.Binding = New Binding("Servername")
Col_Serial.Header = "Servername"
Col_Serial.Width = 40
Dim Col_IPArray = New DataGridComboBoxColumn()
Col_IPArray.Header = "IP Addresses"
Col_IPArray.IsReadOnly = True
'Col_IPArray.ItemsSource = serverInfoArray ' Don't know how to do this.
Col_IPArray.SelectedValuePath = "IPArray"
Col_IPArray.DisplayMemberPath = "IPArray"
DataGrid1.Columns.Add(Col_Serial)
DataGrid1.Columns.Add(Col_IPArray)
DataGrid1.ItemsSource = ServerInfoArray
End Sub
End Class
Class ServerInfo
Dim _Servername As String
Dim _IPArray As ComboBox
Public Property Servername() As String
Get
Return _Servername
End Get
Set(ByVal value As String)
_Servername = value
End Set
End Property
Public Property IPArray As ComboBox
Get
Return _IPArray
End Get
Set(ByVal value As ComboBox)
_IPArray = value
End Set
End Property
Public Sub New()
_Servername = Nothing
_IPArray = New ComboBox
End Sub
End Class
我可以讓所有的字符串和布爾值綁定。
我不知道如何將此DataGridComboBoxColumn綁定到屬性上附加的列表。我無法使用XAML,因爲我需要在運行時執行此操作。
你能舉個快速的例子嗎?這個組合框也應該是隻讀的。我不需要任何用戶輸入。所以你的意思,而不是讓IPArray列表(字符串)它應該是組合框?我以爲我曾嘗試過,但我會再試一次。 – Jasin
好吧我認爲我越來越接近了,我必須從外部綁定itemsource?因爲datagrid綁定到同一個類數組。我仍然無法獲取任何數據。我用我正在嘗試的內容更新了我的代碼。 – Jasin
是的。在Windows窗體中,我已經迭代組合框的每個單元格,並將typecase顯式地作爲組合框並將數據源應用於每個單元格。 –
