It makes no sense at all. Can you explain what exactly you are trying to achieve?
You create a form locally. It simply does nothing.
You don't think you are ready for UI development. It looks like you have little understanding of the very basics, what are types and instances, what constructors do, and do on...

You need to understand the concept of classes and objects first. Creating a new FRM_PatientData form in the datagridview click method is not the way to do it. You need a reference to the original form.

this ismy code in form gridview :-
public partial class FRM_Patient_List : Form
{
SqlConnection con = new SqlConnection("Server= .; Database= GammaCamera; Integrated Security = true");
SqlCommand sCommand;
SqlDataAdapter sdAdapter;
DataTable dt;
string s;

public FRM_Patient_List()
{
InitializeComponent();
}

void FillGridView()
{
try
{
con.Open();
s = " select P_id as , P_Name , case when P_Gender = 1 then 'M' else 'F' end as 'الجنس', P_DateOfBirth , City.City_Name , ";
s = s + " Center.Center_Name , Phone1 , Phone2 , Doctor.Doctor_Name , ";
s = s + " SideName.Side_Name , P_Weight , P_Length , Notes ";
s = s + " from Patients ";
s = s + " inner join City on Patients.City_id = City.City_id ";
s = s + " inner join Center on Patients.Center_id = Center.Center_id ";
s = s + " inner join Doctor on Patients.Doctor_id = Doctor.Doctor_id ";
s = s + " inner join SideName on Patients.Side_id = SideName.Side_id ";
sCommand = new SqlCommand(s, con);
sdAdapter = new SqlDataAdapter();
sdAdapter.SelectCommand = sCommand;
dt = new DataTable();
sdAdapter.Fill(dt);
BindingSource BSource = new BindingSource();
BSource.DataSource = dt;
dGV_Patient.DataSource = BSource;
con.Close();
}
catch
{
return;
}
}

private void FRM_Patient_List_Load(object sender, EventArgs e)
{
FillGridView();
}
