生成.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）

 If (rbCostCenterName.Checked) Then
        Session("CostCenterBy") = "name"
    ElseIf (rbCostCenterNumber.Checked) Then
        Session("CostCenterBy") = "number"
 End If

输出

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

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

【解决方案1】：

好吧，我得到了答案。

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
