维持Treeview状态 [英] Maintain Treeview state

问题描述

有人可以告诉我在c#中重新加载后如何维护treeview节点的状态(展开或折叠)吗?

预先感谢.

解决方案

您将需要在temporaray文件或数据库中写入树状视图状态，并在再次加载表单/程序时检索这些值.

这很容易保存状态，只需按照此处 [ ^ ]，将状态存储在Dictionary对象，然后使用序列化 [ 解决方案

You will need to write treeview state in a temporaray file or the database and retrieve these values when the form / program is loaded again.

That''s simple to save it''s state, Just follow tha way HERE[^], Once you have stored state in Dictionary object then store that object permanantly using Serialization[^], Once page is loaded again, DeSerialize object back and Load tree view again from it.
