我在将子级插入Treeview时遇到问题. [英] i have a problem in inserting child to treeview.

问题描述

大家好，
我的程序是leitner box.我有一个带有某些节点的树形视图.当我向数据库中添加一个单词时，这个单词作为其子级添加到树形视图节点中.但是当我关闭程序并停止调试时，下次我打开并调试program.tree视图为空.为什么?????.my代码在这里:
TreeView1.Nodes.Find("Node36", True)(0).Nodes.Add("G1", txtw.Text)
txtw.text是我写单词的地方.
node36是words的父节点.这意味着我想将此单词作为子代添加.
