本来就可以联动的呀，如果是指2个目录树的条件是同时而不是或者，参考：Dim nms As String() = {"单位","部门","责任人"} '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 flt1,flt2 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
If nd.FullPath Like "按设备*"
nms = {"设备大类","设备二类","设备三类"}
Else
nms = {"单位","部门","责任人"}
End If
Dim rts() As String = nd.FullPath.Split("\")
Dim val As String = ""
For i As Integer = 1 To rts.length - 1
If val > "" Then
val = val & " And "
End If
val = val & nms(i-1) & " = " & qts(i-1) & rts(i) & qts(i-1)
Next
If nd.FullPath Like "按设备*"
If flt2 > "" Then
flt2 = flt2 & " or (" & val & ")"
Else
flt2 = val
End If
Else
If flt1 > "" Then
flt1 = flt1 & " or (" & val & ")"
Else
flt1 = val
End If
End If
End If
Next
Dim flt As String = flt1
If flt > "" Then
If flt2 > "" Then
flt = "(" & flt1 & ") and (" & flt2 & ")"
End If
Else
flt = flt2
End If
Tables("主表").Filter = flt
