If e.node.Level > 0 Then
    Dim t As Table = Tables("个人客户信息")
    Dim filter As String = ""
    Dim dr As DataRow = e.Node.DataRow
   
    If e.node.Level = 0 AndAlso e.node.text = "全部" Then
        t.DataTable.LoadFilter =  ""
        t.DataTable.Load()
       
    Else  If dr("分组") = "按分组" Then
        If e.Node.Level = 1 Then
            filter = "省 = '" & dr("省") & "'"
        Else If e.Node.Level = 2 Then
            filter = "省 = '" & dr("省") & "' and 市 = '" & dr("市") & "'"
