以下代码有个问题，就是取消所有TreeView的复选框后，整个表就全部加载了，可我希望的是清空掉所有数据，不知代码中哪个地方要改下，请老师看看！
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
For Each nd In trv.AllNodes
If nd.Name <> e.Node.Name Then nd.Checked = False
Next
flt = "1=1"
Else
For Each nd In trv.AllNodes
If nd.Checked Then
trv.Nodes(0).Checked = False '最上面"加载所有数据" 选择框去掉
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
Dim flt1 As String = "[工序] not like '销售出库%' and [工序] not like '废品入库' and [工序] not like '来料加工退货' and [工序] not like '盘点出库' and [工序] not like '并卷转出' and [库存标记] = 1"
If e.Form.Controls("CheckBox_仅显库存").checked=True AndAlso flt <> "" Then
DataTables("工序合并表").LoadFilter = flt & "and" & flt1 '设置加载条件
Else
DataTables("工序合并表").LoadFilter = flt '设置加载条件
End If
DataTables("工序合并表").LoadOrder = "卷号,起始时间"
DataTables("工序合并表").Load()
