you can just define an empty datatable without defining columns from your datagridview to it

SqlConnection CN = new SqlConnection(mysql.CON.ConnectionString);
dataGridView1.AutoGenerateColumns = false;
DataTable dt = new DataTable();
SqlDataAdapter sda = new SqlDataAdapter("select id,name,age,notes  from test where id = '" + txtID.Text + "'", CN);
sda.Fill(dt);
dataGridView1.DataSource = dt;
