此主题相关图片如下：2.png

Dim dr As DataRow = e.Node.DataRow '获取生成此节点的行

Dim Year As Integer = dr("年")

Dim pd As String = dr("fa piao类型")

Select Case e.Node.Level

Case 0

Filter ="Year(开piao日期) = " & Year

Case 1

此主题相关图片如下：1.png

Filter ="Year(fa piao日期) = " & Year & " And fa piao类型 = '" & pd & "'"

MessageBox.Show(filter)

End Select

如果是做筛选，没有Year(开piao日期) 这种用法，参考这里日期的处理：http://www.foxtable.com/webhelp/topics/0917.htm

做成这个效果，稍许改了下代码而已

Dim Filter As String

If e.node.Text = "加载所有行" Then

Filter = ""

Else

Dim dr As DataRow = e.Node.DataRow '获取生成此节点的行

Dim Year As Integer = dr("年")

Dim Month As Integer = dr("月")

Dim pd As String = dr("开piao单位简称")

Select Case e.Node.Level

Case 0

Filter ="Year(fa piao日期) = " & Year

Case 1

Filter ="Year(fa piao日期) = " & Year & " And Month(fa piao日期) = " & Month

Case 2

Filter ="Year(fa piao日期) = " & Year & " And Month(fa piao日期) = " & Month & " And 开piao单位简称 = '" & pd & "'"

End Select

End If

DataTables("销项fa piao").LoadFilter = Filter

DataTables("销项fa piao").Load()

看不出哪里有问题。方便做个例子测试一下
