主题：当前日期生成

 呃，datacolchanged事件，改改用

 写错了......

 想一想，二楼的不对，再改一下。

If e.DataCol.name = "日期" Then
    Dim d As Date = e.DataRow("日期")
    Dim d1 As Date = new Date(d.Year, 2, 15)
    Dim d2 As Date = new Date(d.Year, 7, 10)
    Dim d3 As Date = new Date(d.Year, 7, 16)
    Dim d4 As Date = new Date(d.Year, 12, 31)
    Dim d5 As Date = new Date(d.year+1, 2, 14)
    If d >= d1 AndAlso d <= d2 Then
        e.DataRow("学期") = d.Year & "年(春)"
    Else If d >= d3 AndAlso d <= d4 Then
        e.DataRow("学期") = d.Year & "年(秋)"
    Else If d > d4 AndAlso d <= d5 Then
        e.DataRow("学期") = (d.Year-1) & "年(秋)"
    End If
End If
