private void btnSave_Click(object sender, EventArgs e)
{
  if (txtID.Text.Trim()== "")
  {
    labelID.Text = "!";
  }
        
  if (txtLastName.Text.Trim()=="")
  {
    labelLN.Text = "!";
  }
  if (txtFirstName.Text.Trim()=="")
  {
    labelFN.Text = "!";
  }
  if (txtMiddleName.Text.Trim()=="")
  {
    labelMI.Text = "!";
  }
  else
  {
    DialogResult dialogresult = MessageBox.Show("Successfully save.", "Books",MessageBoxButtons.OK, MessageBoxIcon.Question);
    if (dialogresult == DialogResult.Yes)
    {
      string myCon = ...;
      string Query = ....
