You should set AutoGenerateColumns=false and add the specific column manually.

in your aspx page set dataGridView1 AutoGenerateColumn = false;
then in BoundColumn set DataField = "attn_id";
and then update your code as below.

C#

private void tmst_timein_new_Load(object sender, EventArgs e)
        {
         try
         {
            using (TMPB_attn_DAL dalObj = new TMPB_attn_DAL())
          {
              dataGridView1.DataSource = dalObj.GetRecords();
              dataGridView1.DataBind();

                }
            }
            catch (Exception es)
            {
                MessageBox.Show(es.Message);

            }
        }
