--  一个条件的问题
请教老师,我写的代码,点击目录树节点,不会按条件选择,表的行都显示出来了

Dim dr As DataRow = e.Node.DataRow \'获取生成此节点的行  
Dim Filter As String
Filter = "上传类型_商务文件 = True"
Dim Year As Integer = dr("年").Replace("年", "")
Dim Month As Integer = dr("月").Replace("月", "")
Dim Product As String = dr("信息编号")
Select Case e.Node.Level
    Case 0
        Filter ="Year(上传时间) = " & Year
    Case 1
        Filter ="Year(上传时间) = " & Year & " And Month(上传时间) = " & Month
    Case 2
        Filter ="Year(上传时间) = " & Year & " And Month(上传时间) = " & Month & " And 信息编号 = \'" & Product & "\'"
End Select
DataTables("查询_Table20").LoadFilter = Filter
DataTables("查询_Table20").Load()

改写这样,到是可以了,不知这样写代码可对
Dim dr As DataRow = e.Node.DataRow \'获取生成此节点的行  20160810
Dim Filter As String
Dim Year As Integer = dr("年").Replace("年", "")
Dim Month As Integer = dr("月").Replace("月", "")
Dim Product As String = dr("信息编号")
Select Case e.Node.Level
    Case 0
        Filter ="Year(上传时间) = " & Year & " And 上传类型_商务文件 = True "
    Case 1
        Filter ="Year(上传时间) = " & Year & " And Month(上传时间) = " & Month & " And 上传类型_商务文件 = True "
    Case 2
        Filter ="Year(上传时间) = " & Year & " And Month(上传时间) = " & Month & " And 信息编号 = \'" & Product & "\'" & " And 上传类型_商务文件 = True "
End Select
DataTables("查询_Table20").LoadFilter = Filter
DataTables("查询_Table20").Load()
