Do it this way (make necessary changes in code)..

            SqlConnection con = new SqlConnection(GetConnectionString());
            con.Open();
            SqlCommand cmd = new SqlCommand("CheckUser", con);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlParameter p1 = new SqlParameter("username", username.Text);
            SqlParameter p2 = new SqlParameter("password", password.Text);
            cmd.Parameters.Add(p1);
            cmd.Parameters.Add(p2);
            SqlDataReader rd = cmd.ExecuteReader();
            if(rd.HasRows)
            {
                //do the things
            }
            else
            {
                lblinfo.Text = "abc";
            }
