我无法将DataGridComboBoxColumn绑定到数据表

Question

我是WPF的新手，我遇到的问题应该看似简单。我有一个数据表，我试图绑定到DataGridComboBoxColumn。这是我的代码=请指教。加载时没有显示组合框。

 <CollectionViewSource x:Key="ColorListData"/>

<DataGridComboBoxColumn Header="Color"  ItemsSource="{Binding Source=   {StaticResource ColorListData}}" x:Name="myColorComboBox" DisplayMemberPath="ColorName"   SelectedValuePath="DataID" />

 code behind:

                        Dim ColorListData As System.Windows.Data.CollectionViewSource = CType(Me.FindResource("ColorListData"), System.Windows.Data.CollectionViewSource)
    Dim Sql As String = "Select DataID, ColorName from Colors where StyleID = @StyleID"
    ReDim SqlP(0)
    SqlP(0) = MyData.CreateParameter("StyleID", SqlDbType.Int, 4, StyleID)
    Dim MyColorTable As DataTable = MyData.GetDataTable(Sql, "text", SqlP)
    ColorListData.Source = MyColorTable.DefaultView
