Asp.net 从数据集调用数据（嵌套If）

Generate.aspx.vb

Case "costcentersummary"
            Dim newparams(4) As ReportParameter
            newparams(0) = New ReportParameter("CallClassCode", callClassCode)
            newparams(1) = New ReportParameter("DateTimeFrom", startDateTime)
            newparams(2) = New ReportParameter("DateTimeTo", endDateTime)
            newparams(3) = New ReportParameter("Vat", vat)
            newparams(4) = New ReportParameter("CostCenterBy", costcenterby)
            rvScreen.LocalReport.SetParameters(newparams)
            rvScreen.LocalReport.Refresh()

            Dim rdsCostCenterSummary As New ReportDataSource
            Dim daCostCenterSummary As New CostCenterSummaryTableAdapter
            Dim dtCostCenterSummary As New CostCenterSummaryDataTable

            Dim filters = reportFilter.Split(",")
            Dim ta As New LCSRDBDataSetTableAdapters.CostCentersLookupTableAdapter
            Dim dt = ta.GetData(siteId)

            If String.IsNullOrEmpty(reportFilter) Or filters.Count = dt.Rows.Count Then
                daCostCenterSummary.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_call_class_code = 'OUTGOING' AND cdr_call_type_id IN({4}) GROUP BY cdr_id", siteId, startDateTime, endDateTime, callClass, callType))
            Else
                daCostCenterSummary.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_call_class_code = 'OUTGOING' AND cdr_call_type_id IN({4}) AND cost_center_id IN ({5}) GROUP BY cdr_id", siteId, startDateTime, endDateTime, callClass, callType, reportFilter))
            End If

            daCostCenterSummary.Fill(dtCostCenterSummary)

            rdsCostCenterSummary.Name = "LCSRDBDataSet_CostCenterSummary"
            rdsCostCenterSummary.Value = dtCostCenterSummary
            rvScreen.LocalReport.DataSources.Add(rdsCostCenterSummary)

Standard.aspx.vb（会话）

输出

问题：
如何在generate.aspx.vb中嵌套if语句？
还是应该在standard.aspx.vb中对其进行编码？
如何从数据集中调用值？
可能吗？
或者我应该在rdlc报告中编写代码

这个想法是：

if(ByCostCenterName is checked) then
  CostCenterName is in alphabetical order
  if(ByCostCenterNumber is checked) then
    CostCenterNumber is in ascending order
  end if
end if

好吧，我知道答案了

在Generate.aspx.vb中，我在其中插入了以下代码

If costcenterby = "name" Then
  daCostCenterSummary.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_call_class_code = 'OUTGOING' AND cdr_call_type_id IN({4}) GROUP BY cdr_id ORDER BY department_description", siteId, startDateTime, endDateTime, callClass, callType))
Else
  daCostCenterSummary.SetWhereClause(String.Format("cdr_site_id = '{0}' AND cdr_datetime BETWEEN '{1}' AND '{2}' AND cdr_call_class_code = 'OUTGOING' AND cdr_call_type_id IN({4}) GROUP BY cdr_id ORDER BY cost_center_description", siteId, startDateTime, endDateTime, callClass, callType))
End If

End If
