又有小问题，不知在那里改代码，下面代码执行后，筛选没有问题，但当我先选了下面的一些节点，最后点上面的“加载所有数据”的选择框后，下面已经选择的节点前选择框还处于选中状态，如何在点了上面的“加载所有数据”的选择框后把这些下面的选择框自动变成不选中状态？
Dim nms As String() = {"牌号","母卷号","卷号"} '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
If e.node.Text = "加载所有数据" Then
flt = "1=1"
Else
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
End If
Tables("工序合并表查询独立窗口_Table_工序合并表").Filter = flt
