主题：[原创]树存回原表没反应

以下是重命名一个树节点名，然后存回原表，怎么原表没反应？

Dim tr As WinForm.TreeView
tr = e.Form.Controls("TreeView1")
tr.Select()
tr.BeginEdit()

Dim nd As WinForm.TreeNode = tr.SelectedNode
Dim id As Integer = nd.index

Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim nds As List(of Winform.TreeNode) = trv.AllNodes
DataTables("商品").DataRows(id)("条码") = nds(id).fullpath
