如何從radTreeListView SelectedItems集合檢索所有檢查的項目

Question

如何檢索從radTreeListView SelectedItems集合在c＃中的所有檢查的項目？

下面的示例從Retrieve All Checked Items根本不工作。

foreach (object checkedItem in radTreeView.CheckedItems) 
{ 
    // Get the container(RadTreeViewItem) of the checked item 
    RadTreeViewItem container = radTreeView.ContainerFromItemRecursive(checkedItem); 
    // Add your logic for handling the checked item scenario here 
} 

爲RadTreeListView的XML是

<telerik:RadTreeListView x:Name="radTreeListView" ItemsSource="{Binding Items}" 
     AutoGenerateColumns="False" Grid.RowSpan="2" SelectionChanged="radTreeListView_SelectionChanged" SelectionMode="Extended" SelectedItem="{Binding SelectedItem, Mode=TwoWay}" SelectionChanging="radTreeListView_SelectionChanging" BeginningEdit="radTreeListView_BeginningEdit"> 
      <telerik:RadTreeListView.ChildTableDefinitions> 
       <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}" /> 
      </telerik:RadTreeListView.ChildTableDefinitions> 
      <telerik:RadTreeListView.Columns> 
       <telerik:GridViewSelectColumn/> 
       <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name" /> 
       </telerik:RadTreeListView.Columns> 
     </telerik:RadTreeListView>

SelectedItems是關鍵！

我準備了SampleData，如here所述，並使用以下代碼捕獲檢查的項目。

System.Collections.ObjectModel.ObservableCollection<object> selected_items = radTreeListView.SelectedItems; 
     foreach (object item in selected_items) 
     { 
      WarehouseItem warehouseitem = (WarehouseItem)item; 
      MessageBox.Show(warehouseitem.Name); 
     }
