       con.Open()
       listFilter = Nothing
       listFilter = BindName()
       'fetching course deatil'
       If Not IsPostBack Then

           da = New SqlDataAdapter(cm)
           ds = New DataSet
           da.Fill(ds, "cour")
           dt = New DataTable
           dt = ds.Tables("cour")
           While i <= dt.Rows.Count - 1
               Me.dl_course1.Items.Add(dt.Rows(i).Item("course_name").ToString)
               i = i + 1
           End While

           i = 0
       End If
       Me.dl_course1.Focus()
   End Sub

Private Function BindName() As String
     Dim dt As DataTable = Nothing

     Dim output As New StringBuilder()
     output.Append("[")
     For i As Integer = 0 To dt.Rows.Count - 1
         output.Append("""" & dt.Rows(i)("empid_name").ToString() & """")

         If i <> (dt.Rows.Count - 1) Then
             output.Append(",")
         End If
     Next
     output.Append("];")
     Return output.ToString()
 End Function
