<ListView
    x:Name="taskItemListView"
    DataContext="{Binding SelectedItem,ElementName=itemListView}"
    ItemsSource="{Binding taskItems}">
...
</ListView>

我已经尝试了以下代码,但它似乎不起作用……

Binding b = new Binding();
b.Path = new PropertyPath("taskItems");

DependencyProperty dp = DependencyProperty.Register("itemsSource",typeof(object),null);
BindingOperations.SetBinding(taskItemListView,dp,b);

编辑：

基于@ sa_ddam213的答案,这有效：

Binding dataContextBinding = new Binding();
dataContextBinding.Path = new PropertyPath("SelectedItem");
dataContextBinding.Source = itemListView;
BindingOperations.SetBinding(taskItemListView,ListView.DataContextProperty,dataContextBinding );

Binding sourceBinding = new Binding();
sourceBinding.Path = new PropertyPath("taskItems");
BindingOperations.SetBinding(taskItemListView,ListView.ItemsSourceProperty,sourceBinding );
