สอบถาม การเรียก Bind ค่า เพื่อโชว์ข้อมูล GridView ค่ะ

Sub ShowGrid()
 
    BindGrid("FEVGRDCD is not null  ORDER BY FEVGRDCD")
   
  End Sub

Public Function Selected(ByVal stringCondition As String) As DataTable
      'Dim ds As DataSet = db.Selected(tbl_name, "FEVGRDCD, FEVGRDDS, FEVGRDSCS,FEVGRDSCS,FEVGRDSCE,FEVSCORERE,FEVPAR,FEVPQCASE1,FEVPQCASE2 CASE WHEN FNOTUSE = 'N'  END AS FNOTUSE ", stringCondition)
      Dim ds As DataSet = db.Selected(tbl_name, "FEVGRDCD, FEVGRDDS, FEVGRDSCS,FEVGRDSCS,FEVGRDSCE,FEVSCORERE,FEVPAR,FEVPQCASE1,FEVPQCASE2 CASE WHEN FNOTUSE = 'N'  END AS FNOTUSE", stringCondition)
      Dim dt_result As DataTable = ds.Tables(0)

      '//return insert result
      Return dt_result
    End Function
