我有一个CollectionViewSource我ItemsSource的DataGrid. 在Window.Resources我有这个定义：

<CollectionViewSource x:Key="ItemsPoolCollectionView"  
     Source="{Binding Path=MyObservableCollection, Mode=OneWay}" />

现在，我想从代码中生成相同的定义，所以我这样做了：

Dim _cvs as CollectionViewSource = New CollectionViewSource
Dim bindSource = New Binding() With {
        .Path = New PropertyPath("MyObservableCollection"),
        .Mode = BindingMode.OneWay }
_cvs.SetValue(CollectionViewSource.SourceProperty, bindSource)

但我在最后一条语句中有这个错误：

'System.Windows.Data.Binding' is not a valid value for property 'Source'

怎么了？我怎样才能做到这一点？

我解决！...这样：

      Dim _cvs as CollectionViewSource = New CollectionViewSource
      Dim bindSource = New Binding() With {
              .Source = Me.DataContext
              .Path = New PropertyPath("MyObservableCollection"),
              .Mode = BindingMode.OneWay }
      BindingOperations.SetBinding(cvs, CollectionViewSource.SourceProperty, bindSource)

您无需绑定 aCollectionViewSource即可使其自动“绑定”；只需直接设置 Source 属性的值：

Dim _cvs as CollectionViewSource = New CollectionViewSource
_cvs.Source = Me.MyObservableCollection

（对不起我生锈的 VB.net）
