Dim nms As String() = {"一级分类","二级分类","产品名称"} '指定生成目录树的各列
Dim qts As String() = {"'","'","'"} '指定将各列的值括起来的符号,这里都是字符型,所以都是单引号
Dim trv As WinForm.TreeView = e.Sender
Dim flt As String
Dim nd As WinForm.TreeNode
For Each nd In e.node.allNodes '清除子节点的选中标记
nd.Checked = False
Next
nd = e.Node.ParentNode
Do While nd IsNot Nothing '清除父节点的选中标记
nd.Checked = False
nd = nd.ParentNode
Loop
For Each nd In trv.AllNodes
If nd.Checked Then
Dim rts() As String = nd.FullPath.Split("\")
Dim val As String = ""
For i As Integer = 0 To rts.length - 1
If val > "" Then
val = val & " And "
End If
val = val & nms(i) & " = " & qts(i) & rts(i) & qts(i)
Next
If flt > "" Then
flt = flt & " Or (" & val & ")"
Else
flt = val
End If
End If
Next
Dim a,b As Double
a = Forms("窗口2").Controls("ComboBox1").text
b = Forms("窗口2").Controls("ComboBox2").text
If flt Is Nothing Then
DataTables("订单").LoadFilter = "[折扣] > " & a & " And [折扣] < " & b
DataTables("订单").Load
Else
DataTables("订单").LoadFilter = flt & " And [折扣] > " & a & " And [折扣] < " & b
DataTables("订单").Load
End If
问题：
当选择单个节点时满足复合筛选要求，但选择第二个及以上节点节点，附加条件” [折扣] > " & a & " And [折扣] < " & b
”即不起作用。
