Data Text Field from MySQL Database displaying as System.Byte in ASP.Net

I am using mysql database and i am binding radiobuttonlist using query below.On local it is fine But when i upload same code online radio button text shows as System.Byte[].

query="SELECT CONCAT (`desc` ,'- ' , `price`)  AS     `title`,desc  FROM   `ping`"
            db.cmd.CommandText = query
            Dim da As New OdbcDataAdapter(query, db.conn)
            Dim ds As New DataSet
            da.Fill(ds)

            r.DataSource = ds
            r.DataTextField = "title"
            r.DataValueField = "desc"
            r.DataBind()

Is there something wrong i am doing or there is any issue with mysql.

Thanks
