主题：关于筛选目录树的一点问题~~跪求大神指导~...标题长才看的到~~~

 

1、窗口的AfterLoad事件代码改为：

Dim cmd As New SQLCommand
Dim dt As DataTable
cmd.CommandText = "SELECT DISTINCT Year(日期) As 年, Month(日期) As 月, 产品 From {订单}"
dt = cmd.ExecuteReader()
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree(dt, "年|月|产品")

2、目录树的NodeMouseDoubleClick事件代码改为：

Dim Value()As String
Dim Filter As String
Dim d1 As Date
Dim d2 As Date
Value = e.Node.FullPath.Split("\")
Select Case e.Node.Level
    Case 0
        Dim y As Integer = value(0)
        d1 = New Date(y,1,1) '取得该年的第一天
        d2 = new Date(y,12,31) '取得该年的最后一天
        Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "#"
    Case 1
        Dim y As Integer = value(0)
        Dim m As Integer = value(1)
        d1 = New Date(y, m, 1) '取得该月的第一天
        d2 = new Date(y, m, Date.DaysInMonth(y,m)) '取得该月的最后一天
        Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "#"
    Case 2
        Dim y As Integer = value(0)
        Dim m As Integer = value(1)
        d1 = New Date(y, m, 1) '取得该月的第一天
        d2 = new Date(y, m, Date.DaysInMonth(y,m)) '取得该月的最后一天
        Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "# And 产品 = '" & Value(2) & "'"
End Select
Tables("订单").Filter = Filter

 

以上代码是帮助里面的筛选目录树，如果在该目录树的产品的后面再加一级节点，也就是实现年--月--产品---XX   应该怎么设置代码呢？ 跪求帮助

不占地方了，也是筛选树的问题，放一起了

能实现下图的功能吗？单独将一列筛选出来，可以自由组合筛选

0...你这个我知道的 更新后的筛选有多个条件筛选的~~~帮助有的~~你可以去看看~

0....高手都那里去~了 吃饭了么~~求帮助啊~求帮助~~

Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "# And 产品 = '" & Value(2) & "' And 产品 ='" & Value(3) & "'"

........5555拜谢啊~~~虽然还不知道对不对~~但是能帮我就很感谢了~~恩人~~献上菊花一枚~~

晕，干嘛不是玫瑰花呀！

e  语法不对啊~~

1、窗口的AfterLoad事件代码改为：
 
Dim cmd As New SQLCommand
Dim dt As DataTable
cmd.CommandText = "SELECT DISTINCT Year(日期) As 年, Month(日期) As 月, 产品, XX From {订单}"
dt = cmd.ExecuteReader()
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree(dt, "年|月|产品|XX")

2、目录树的NodeMouseDoubleClick事件代码改为
 
Dim Value()As String
Dim Filter As String
Dim d1 As Date
Dim d2 As Date
Value = e.Node.FullPath.Split("\")
Select Case e.Node.Level
    Case 0
        Dim y As Integer = value(0)
        d1 = New Date(y,1,1) '取得该年的第一天
        d2 = new Date(y,12,31) '取得该年的最后一天
        Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "#"
    Case 1
        Dim y As Integer = value(0)
        Dim m As Integer = value(1)
        d1 = New Date(y, m, 1) '取得该月的第一天
        d2 = new Date(y, m, Date.DaysInMonth(y,m)) '取得该月的最后一天
        Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "#"
    Case 2
        Dim y As Integer = value(0)
        Dim m As Integer = value(1)
        d1 = New Date(y, m, 1) '取得该月的第一天
        d2 = new Date(y, m, Date.DaysInMonth(y,m)) '取得该月的最后一天
        Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "# And 产品 = '" & Value(2) & "'"
   Case 3
        Dim y As Integer = value(0)
        Dim m As Integer = value(1)
        d1 = New Date(y, m, 1) '取得该月的第一天
        d2 = new Date(y, m, Date.DaysInMonth(y,m)) '取得该月的最后一天
        Filter = "日期 >= #" & d1 & "# And 日期 <= #" & d2 & "# And 产品 = '" & Value(2) & "' And XX = '" & Value(3) & "'"
End Select
Tables("订单").Filter = Filter

那

Dim cmd As New SQLCommand
Dim dt As DataTable
cmd.CommandText = "SELECT DISTINCT Year(日期) As 年, Month(日期) As 月, 产品 From {订单}"
dt = cmd.ExecuteReader()
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree(dt, "年|月|产品")

 这个语法不需要改么~~
