[英]Insert and retrieve data from database to TreeView control in C# WinForms
问题描述
I am working with a project, in which I have a task that Names represents with hierarchy in a treeview control.
我正在处理一个项目，在该项目中，我有一个任务，名称在树视图控件中用层次结构表示。
That means I must able to add the parent and child nodes to treeview and when I click Save button all the nodes should be stored in database.这意味着我必须能够将父节点和子节点添加到树视图中，当我单击“保存”按钮时，所有节点都应存储在数据库中。
My typical task is, if I retrieve the data, all the parent and child node should retrieved and added to the treeview control as I inserted hierarchy only.我的典型任务是，如果我检索数据，则所有父节点和子节点都应该检索并添加到树视图控件中，因为我只插入了层次结构。
