主题：e.getvalues传值问题

filter.htm

...

wb.AddForm("", "form2", "gylist.htm")

With wb.AddButtonGroup("", "btg2", False) '垂直排列
          .Add("btn2", "确认", "button", "gylist.htm?Date = today")        

End With

gylist.htm

Dim e As RequestEventArgs = args(0)
Dim wb As New WeUI
Dim flt As String
  MessageBox.Show(e.GetValues("date"))

现在这个显示是空值，请问哪里错了？我只是判断是否有这个键，键值无所谓。
