3 rows data into one column

Hi,

Im working with asp application having controls (1 dropdownlist(options--Schedlue,InProcess,On HOld),two textboxes(SSStatusComments,SSGeneralComments))  I want to show output something  like below

CREATE TABLE [dbo].[EFIWorkStatus1](
	[WID] [int] IDENTITY(1,1) NOT NULL,
	[ST_ID] [int] NULL,
	[SSStatus] [nchar](10) NULL,
	[SSStatusComments] [nvarchar](max) NULL,
	[SSGeneralComments] [text] NULL) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]

 private void SiteSurveystatusload()
    {
        using (SqlConnection cn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["ArgentDB"].ConnectionString))
        {
            cn.Open();

            string sql = "Select  SSStatus,SSStatusComments from EFIWorkStatus1 where  ST_ID=@ST_ID";

            SqlCommand cmd = new SqlCommand(sql, cn);
           cmd.Parameters.AddWithValue("@ST_ID", Request.QueryString["ID1"]);
            using (SqlDataReader reader = cmd.ExecuteReader())
            {
                if (reader.HasRows)
                {


                    while (reader.Read())
                    {

                        txt_SiteSurveyGeneralComments.Text = reader["SSStatus"].ToString() + " " + reader["SSStatusComments"].ToString();
                    }
                }
                else
                {
                    txt_SiteSurveyGeneralComments.Text = "";
                }

            }
        }

    }

output in database  for  above   code 
WID    ST_ID    SSStatus          SSStatusComments  SSGeneralComments
