感觉不一样，用select筛选出来符合条件的所有行后，怎么才能判断这些行里面有没有包含指定的文字（暂解决，帖子发出后不能撤销，比较麻烦）

1、请换成2楼的方式处理。

2、包含文字的判断，请用like，参考 http://www.foxtable.com/webhelp/scr/1647.htm

现在能够选择第一个节点，第二个节点显示不正确，应该怎么改
Dim trv1 As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim trv2 As WinForm.TreeView = e.Form.Controls("TreeView2")
Dim mc As String = "& e.Node.Name &"
Dim drs As List(Of DataRow) = DataTables("用户_授权").Select("用户 like \'*"& e.Node.Name &"*\'")

For Each nd As WinForm.TreeNode In trv2.AllNodes
nd.Checked = False
Next

For Each dr As DataRow In DataTables("用户_授权").Select("用户 like \'*"& e.Node.Name &"*\'")
For Each nd1 As WinForm.TreeNode In trv2.Nodes
nd1.Checked = dr("父节点").Contains(nd1.Name) And dr.IsNull("子节点")
For Each nd2 As WinForm.TreeNode In trv2.Nodes(nd1.Name).Nodes
nd2.Checked = dr("子节点").Contains(nd2.Name)
Next
Next
Next

弄了一两天还是没有弄出来，麻烦看看需要怎么改，现在一选择用户后，用户单元格就会出现所有用户

Dim trv1 As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim trv2 As WinForm.TreeView = e.Form.Controls("TreeView2")
Dim nd1 As WinForm.TreeNode = trv1.SelectedNode
Dim nd2 As WinForm.TreeNode = trv2.SelectedNode
Dim dr As DataRow
Dim sl As Integer

If nd2.Level = 0 Then
dr = DataTables("用户_授权").Find("父节点 = \'"& e.Node.Name &"\'")
ElseIf nd2.Level = 1 Then
dr = DataTables("用户_授权").Find("父节点 = \'"& e.Node.ParentNode.Name &"\' and 子节点 = \'"& e.Node.Name &"\'")
End If

If dr IsNot Nothing Then
Dim nms As String
If e.Node.Level = 0 Then
For Each yh1 As WinForm.TreeNode In trv1.Nodes
If nd2.Checked = True
nms = nms & "," & yh1.Name
End If
If nms > "" Then
dr("用户") = nms.Trim(",")
Else
dr("用户") = Nothing
End If
Next
ElseIf e.Node.Level = 1 Then
For Each yh1 As WinForm.TreeNode In trv1.Nodes
If nd2.Checked = True
nms = nms & "," & yh1.Name
End If
If nms > "" Then
dr("用户") = nms.Trim(",")
Else
dr("用户") = Nothing
End If
Next
End If
End If

我选择目录树第一层节点的最后一个节点，为什么增加，删除用户名的却是这个节点的下一个层级的节点最后一个

Dim trv1 As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim trv2 As WinForm.TreeView = e.Form.Controls("TreeView2")
Dim nd1 As WinForm.TreeNode = trv1.SelectedNode
Dim nd2 As WinForm.TreeNode = trv2.SelectedNode
Dim dr As DataRow
Dim sl As Integer

If nd2.Level = 0 Then
dr = DataTables("用户_授权").Find("父节点 = \'"& e.Node.Name &"\'")
ElseIf nd2.Level = 1 Then
dr = DataTables("用户_授权").Find("父节点 = \'"& e.Node.ParentNode.Name &"\' and 子节点 = \'"& e.Node.Name &"\'")
End If

If nd2.Level = 0 Then
dr = DataTables("用户_授权").Find("父节点 = \'"& e.Node.Name &"\'")
ElseIf nd2.Level = 1 Then
dr = DataTables("用户_授权").Find("父节点 = \'"& e.Node.ParentNode.Name &"\' and 子节点 = \'"& e.Node.Name &"\'")
End If
If dr IsNot Nothing Then
If e.Node.IsSelected = True
If dr("用户").contains(nd1.Text) = False
If dr.IsNull("用户")
dr("用户") = nd1.Text
Else
dr("用户") = dr("用户") & "," & nd1.Text
End If
End If
End If
If e.Node.Checked = False
Dim ss() As String = dr("用户").split(",")
Dim lst As new List(of String)
lst.AddRange(ss)
lst.remove(nd1.Text)
dr("用户") = String.Join(",",lst.ToArray())
End If
End If
