Question

我想在重复广告系列代码和车辆号码时尝试组合行单元格，如下图所示。下面列出的结果是gridview 20页面大小

问题

例如，当网格视图页面大小设置为2时，行单元格不再组合。结果显示每个分开的记录。
如果广告系列代码按升序/降序排序，则即使广告系列代码与车辆号匹配，最后一个记录行单元格也始终不会合并。下图显示的广告系列代码按升序排序。因此，当活动代码按降序排序时，所有CMP002都会合并，而CMP001的最后一条记录将不再组合，如下图所示。

代码背后

 Private Sub GV_RowDataBound(sender As Object, e As GridViewRowEventArgs) Handles GV.RowDataBound

    For rowIndex As Integer = GV.Rows.Count - 2 To 0 Step -1

        Dim gvRow As GridViewRow = GV.Rows(rowIndex)
        Dim gvPreviousRow As GridViewRow = GV.Rows(rowIndex + 1)
        Dim sCurrCampaignCode As String = GV.DataKeys(rowIndex).Values("CAMPAIGN_CODE")
        Dim sCurrVehicleNo As String = GV.DataKeys(rowIndex).Values("VEHICLE_NO")
        Dim sPreviousCampaignCode As String = GV.DataKeys(rowIndex + 1).Values("CAMPAIG_CODE")
        Dim sPreviousVehicleNo As String = GV.DataKeys(rowIndex + 1).Values("VEHICLE_NO")


        If sCurrCampaignCode = sPreviousCampaignCode AndAlso sCurrVehicleNo = sPreviousVehicleNo Then

            If sCurrCampaignCode = sPreviousCampaignCode Then

                    If gvPreviousRow.Cells(1).RowSpan < 2 Then
                        gvRow.Cells(1).RowSpan = 2
                        gvRow.Cells(2).RowSpan = 2
                        gvRow.Cells(3).RowSpan = 2
                    Else
                        gvRow.Cells(1).RowSpan = gvPreviousRow.Cells(1).RowSpan + 1
                        gvRow.Cells(2).RowSpan = gvPreviousRow.Cells(2).RowSpan + 1
                        gvRow.Cells(3).RowSpan = gvPreviousRow.Cells(3).RowSpan + 1
                    End If

                    gvPreviousRow.Cells(1).Visible = False
                    gvPreviousRow.Cells(2).Visible = False
                    gvPreviousRow.Cells(3).Visible = False
            End If

        End If

    Next

End Sub

我刚刚找到了解决方案。代码必须从RowDataBound移动到OnDataBound而不是

将行单元组合用于中继器记录
