WPF VB.NET 4.0 DatagridComboBoxColumn运行时绑定

我对DatagridComboboxColumn有一个类似的问题，但它告诉我如何使用.itemsource绑定到数据网格之外的数组。我在尝试绑定到数据网格在运行时绑定的集合时遇到问题。WPF VB.NET 4.0 DatagridComboBoxColumn运行时绑定

我已经包含了一个工作测试程序，用于处理这个问题。

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

我可以让所有的字符串和布尔值绑定。

我不知道如何将此DataGridComboBoxColumn绑定到属性上附加的列表。我无法使用XAML，因为我需要在运行时执行此操作。

Dim Col_Serial As DataGridComboColumn = New DataGridComboColumn() 
    Col_Serial.ItemSource = GetData(); 
    Col_Serial.SelectedValuePath = "ID_value"; 
    Col_Serial.DisplayMemberPath = "displya_col"; 
    Col_Serial.Header = "Disk4" 
    Col_Serial.Width = 40 
Col_Serial.IsEnabled= false; 
dg.Columns.Add(Col_serial);

你能举个快速的例子吗？这个组合框也应该是只读的。我不需要任何用户输入。所以你的意思，而不是让IPArray列表（字符串）它应该是组合框？我以为我曾尝试过，但我会再试一次。 – Jasin

好吧我认为我越来越接近了，我必须从外部绑定itemsource？因为datagrid绑定到同一个类数组。我仍然无法获取任何数据。我用我正在尝试的内容更新了我的代码。 – Jasin

是的。在Windows窗体中，我已经迭代组合框的每个单元格，并将typecase显式地作为组合框并将数据源应用于每个单元格。 –
