Dim sColList, sTableName As String
Dim DT_Data As New RS_UtilityService.dsSDFSystem.sp_DynamicSQLDataTable
Dim ds As New DataSet
Dim table1 As New DataTable


sTableName = ListColumn.DataSource(0)("TABLE_NAME").ToString
sColList = "*"
If ListRptCol.ItemCount > 0 Then
Dim DT As DataTable = ListRptCol.DataSource
sColList = ""
For iCnt = 0 To DT.Rows.Count - 1
If DT(iCnt)("SOURCE").ToString = "CALC" Then
sColList += "|" & DT(iCnt)("COLUMN_NAME").ToString & "=(" & DT(iCnt)("FORMULA").ToString & ")"
Else
sColList += "|" & DT(iCnt)("COLUMN_NAME").ToString
End If
Next
sColList = Mid(sColList, 2)
End If


r_sSQL = "Select Top(" & txtRecordNo.Text & ") " & sColList.Replace(CChar("|"), CChar(",")) & " From " & sTableName & _
" Where 0=0" & sParameter


If chkPreviewData.CheckState = CheckState.Unchecked Then r_sSQL += " And 1=0 "
Try
DT_Data = RiskkServices.UtilityService.GetDynamicData(r_sSQL)
Catch ex As Exception
RiskkCommonLib.RiskkMsg.ShowMsg(ex.Message, "Error", MessageBoxButtons.OK, Utils.MessageBoxExLib.MessageBoxExIcon.Error)
End Try
grdReport.DataSource = DT_Data
grdV.RefreshData()
grdV.BestFitColumns()
