【搞定】[请求]怎么取DataTreeList1的父节点！**

dupit · 发表于 2007-4-18 18:53:08

看过http://bbs.justep.com/forum.php? ... cted是取节点的
那么在DataTreeList1是应该是
DataTreeList1.SelectedNodes();
括号里的参数是什么啊？？
我也想在DataTreeList1中点中一个节点时取它的父节点！
该怎么实现》》？？

能不能取到？

property SelectedCount: Longint;
选中的节点的个数
property SelectedNodes[Longint]: TTreeListNode;
从0开始枚举每一个选中的节点

这些在StudioHelp中都有的

那怎么取到父节点的值啊？

alang · 发表于 2007-4-19 16:14:20

既然是DataTreeList，这个控件是数据绑定的，只要取数据集当前的字段值，根据数据集取他父节点的值

DataTreeList1.FocusedNode.Parent //取当前节点的父节点
