pageCount 相关问题

收藏

我在 PageStart的时候生成了很多控件，其中包括2个textbox.

在  PageHeader_Format 的时候想把它们设成页面信息，就是当前是第1页，共3页之类的。因为是分开显示的，不能用PageInfo这个控件。但是现在代码总不能正常显示。请帮我看一下。这两个控件都在PageHeader里面。谢谢

Private Sub PageHeader_Format(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PageHeader.Format
      Dim tb1 As New DataDynamics.ActiveReports.TextBox
      Dim tb2 As New DataDynamics.ActiveReports.TextBox

      For Each item As DataDynamics.ActiveReports.ARControl In Me.PageHeader.Controls()

         If item.Name = "TEXT_1" Then
            tb1 = CType(item, DataDynamics.ActiveReports.TextBox)
            Continue For
         End If
         If item.Name = "TEXT_2" Then
            tb2 = CType(item, DataDynamics.ActiveReports.TextBox)
            Continue For
         End If
      Next

      tb1.SummaryRunning = SummaryRunning.All
      tb1.SummaryType = SummaryType.PageCount

      tb2.SummaryType = SummaryType.PageCount

End Sub
