e.Form.Controls("TreeView2").BuildTree("订单清单", "楼层|房间|类别|产品名")
e.Form.Controls("TreeView2").BuildTree("订单清单", "房间|楼层|类别|产品名")
e.Form.Controls("TreeView2").BuildTree("订单清单", "产品名|房间")
e.Form.Controls("TreeView2").BuildTree("订单清单", "类别|楼层|房间|产品名")
四种情况筛选模式
AfterCheckNode
代码入下
勾选复选框会不正常
如何改变呢
Dim nms As String() = {"楼层","房间","产品名","类别"} '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
Tables("订单总表.订单清单").Filter = flt
