用日期列做目录树 怎么去掉时间部分?

Dim tv As WinForm.TreeView
tv =e.Form.Controls("TreeView1")
Dim cm As WinForm.CheckedComboBox = e.Form.Controls("CheckedComboBox1")
Dim cmd As New SQLCommand
Dim dt As DataTable
cmd.C
cmd.CommandText = "SELECT * From {订单}"
dt = cmd.ExecuteReader()
Dim str As String = cm.Value
Dim x As String
Dim Values() As String
Values = Str.split(",")
For Index As Integer = 0 To Values.Length - 1
    For Each cl As DataCol In dt.DataCols
        If Values(Index)= cl.Name  Then
            x= x & cl.Name & "|"
        End If
    Next
Next
tv.Nodes.Clear
tv.BuildTree("订单", x)

 

  我动态生成的,怎么修改这个呢?

老大,我试试

不对呀,老大,我这个本身就是没有问题,只是加载日期列的时候  有时间部分出现,我想去掉而已,你这个还是有.

另外一个,我这个因为是可以随意组合节点的,那么筛选的代码我应该怎么写?
