1.这段是树的"重命名"按钮,"重命名"操作以后立即存入表,但表中数据没修改,请帮忙看一下.

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

2.从表中读出树时,树控件公重新按字母顺序重排树,这样再存回去顺序就变了.怎么办?
