目录树语法错误问题 - 专家坐堂 - Foxtable(狐表) - 新一代数据库软件，完美融合Access、Foxpro、Excel、vb.net之优势，人人都能掌握的快速软件开发工具!

如下：

在AfterSelectNode的代码：

If e.Node.DataRow Is Nothing Then

Tables("B_Room").Position = Tables("B_Room").FindRow("_Identify = " & e.Node.tag)

Else

Tables("B_Room").Position = Tables("B_Room").FindRow(e.node.DataRow)

End If

在AfterEditNode的代码：

If e.NewText = "" Then

e.Cancel = True

Return

End If

Dim pth() As String = e.Node.FullPath.Split("\")

Select Case e.node.Level

Case 0

DataTables("B_Room").ReplaceFor("仓库一级",e.NewText,"仓库一级 = '" & pth(0) & "'")

Case 1

DataTables("B_Room").ReplaceFor("仓库二级",e.NewText,"仓库一级 = '" & pth(0) & "' And 仓库二级 = '" & pth(1) & "'")

Case 2

DataTables("B_Room").ReplaceFor("仓库三级",e.NewText,"仓库一级 = '" & pth(0) & "' And 仓库二级 = '" & pth(1) & "' And 仓库三级 = '" & pth(2) & "'")

Case 3

DataTables("B_Room").ReplaceFor("仓库四级",e.NewText,"仓库一级 = '" & pth(0) & "' And 仓库二级 = '" & pth(1) & "' And 仓库三级 = '" & pth(2) & "' And 仓库四级 = '" & pth(3) & "'")

Case 4

DataTables("B_Room").ReplaceFor("仓库伍级",e.NewText,"仓库一级 = '" & pth(0) & "' And 仓库二级 = '" & pth(1) & "' And 仓库三级 = '" & pth(2) & "' And 仓库四级 = '" & pth(3) & "' And 仓库伍级 = '" & pth(4) & "'")

Case 5

DataTables("B_Room").ReplaceFor("仓库六级",e.NewText,"仓库一级 = '" & pth(0) & "' And 仓库二级 = '" & pth(1) & "' And 仓库三级 = '" & pth(2) & "' And 仓库四级 = '" & pth(3) & "' And 仓库伍级 = '" & pth(4) & "' And 仓库六级 = '" & pth(5) & "'")

End Select

e.Node.Name = e.NewText

在窗体按钮增加仓库的代码如下：

Dim dr As DataRow = DataTables("B_Room").AddNew

dr("仓库一级") = "新节点"

Dim tr As WinForm.TreeView

Dim nd As WinForm.TreeNode

tr = e.Form.Controls("TreeView1")

nd = tr.Nodes.Add("新节点")

tr.SelectedNode = nd

tr.Select()

tr.BeginEdit()

当在点击增加的时候会出现以下的问题，请问是什么问题？

.NET Framework 版本：2.0.50727.8669

Foxtable 版本：2017.12.18.1

错误所在事件：窗口,仓库管理,TreeView1,AfterSelectNode
