我在我的视图中得到了这个，我需要能够通过右键单击 - ＆gt;编辑TreeView中的Skeleton项目的名称。上下文菜单 - ＆gt;改名。有一个小问题：
当我使用TextBlock时它工作正常（TextBlock不可编辑）但是当我使用TextBox时绑定关闭。我尝试了几种绑定和祖先类型，但无济于事。不确定我是否应该切换到TextBox。

当我使用TextBox时，这些是输出中的错误：
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=Root'. BindingExpression:Path=DataContext.AvailableSkeletonColors; DataItem=null; target element is 'ColorPicker' (Name=''); target property is 'StandardColors' (type 'ObservableCollection`1')
和
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.UserControl', AncestorLevel='1''. BindingExpression:Path=DataContext; DataItem=null; target element is 'TextBox' (Name=''); target property is 'Tag' (type 'Object')
感谢您的每一个输入！
