我有一个名为gvForecasts的ASPX gridview
这有一个标题为一年中的每一周;第1周第2周第3周等。
我希望能够遍历这些列以查明它是否小于今天的日期。但是要做到这一点，我需要首先弄清楚如何获取列标题值。
任何帮助都会很棒。

Init事件如下;
Protected Sub gvForecasts_Init(sender As Object, e As EventArgs)
Dim dat As String = DatePart(DateInterval.WeekOfYear, Now)
Dim WeekNum As String = "Week " & dat
End Sub
