private void btnSave_Click(object sender, EventArgs e)
      {
          string s = dtpdue_date.Value.ToString();
          string s1 = dtpcompletiondate.Value.ToString();

          string connectionstr = "Data Source=TUSHAR-PC;Initial Catalog=callcenter;Persist Security Info=True;User ID=sa;Password=password@123";
          string sql = "Insert into tasks(t_id,Name,Priority,status,Due_date,description,date of completion)"+txtT_id.Text+",'"+txtname.Text+"','"+cbopriority.Text+",'"+cboStatus.Text+"','"+ s+"','"+txtcomments.Text+"'.'"+s1+"')";
