WPF樹型視圖

Question

建議我有這樣的樹視圖：

<TreeView Height="295" HorizontalAlignment="Left" Margin="11,58,0,0" Name="treeView1" VerticalAlignment="Top" Width="260" Grid.ColumnSpan="2"> 
      <TreeViewItem Header="Boek" Name="BoekenLijst" Width="260" HorizontalContentAlignment="Stretch" /> 
      <TreeViewItem Header="CD" Name="CDLijst" Width="260" /> 
      <TreeViewItem Header="DVD" Name="DVDLijst" Width="260" /> 
     </TreeView> 

在3個Treeviewitems我把動態的treeviewitems與它的複選框。

我試圖刪除選定的項目，現在我這樣做：

TreeViewItem parent = treeView1.SelectedItem as TreeViewItem; 
    //What do i need to put here so i can remove the selected childs? 

Answer 1

如果要直接刪除選定的項目，請嘗試：

treeView1.Items.Remove(treeView1.SelectedItem); 

如果你想刪除所選項目的所有子項目：

ObservableCollection<TreeViewItem> helper = new ObservableCollection<TreeViewItem>(); 
foreach(TreeViewItem item in treeView1.SelectedItem.Items) 
{ 
    helper.Add(item); 
} 

foreach(TreeViewItem item in helper) 
{ 
    treeView1.SelectedItem.Items.Remove(item); 
}
