and I Called the GetPatient(int ..) By Find Button , the Code Of Button Find is : -

private Patients _patient = new Patients();
private void btnFind_Click(object sender, EventArgs e)
{
try
{
_patient = new Patients();

_patient.GetPatient(int.Parse(txtPatientID.Text));

txtPatientID.Text = _patient.PatientId.ToString();
txtFirstName.Text = _patient.Firstname;
txtLastName.Text = _patient.Lastname;

btnDelete.Enabled = true;
btnSave.Enabled = false;
}
catch (FormatException ez)
{
MessageBox.Show("Plz Enter Right Format", ez.ToString());

}
}
