Pass object from another form to other c#

Lm Martiness

Hi everyone
How can i pass this method from another form to other

public class arka_data
{
public int NR { get; set; }
public int BARKODI { get; set; }
public string EMERTIMI { get; set; }
public int SASIA {get;set;}
public float CMIMI {get;set;}
public float TVSH { get; set; }
public float TOTAL { get; set; }
public float NENTOTALI { get; set; }
public float ZBRITJA { get; set; }
public float TOTALI { get; set; }
public DateTime KOHA { get; set; }
public string KASIERI { get; set; }
public string KLIENTI { get; set; }
public float VLERAETVSH { get; set; }
public float VLERAPATVSH { get; set; }
public int NRATIKUJVE { get; set; }
public float TOTALIPCS { get; set; }
public float VLERATVSHTOTAL { get; set; }

}
public void mbushe()
{
arka_data dta = new arka_data();
for (int i = 0; i < dataTable.Rows.Count; i++)
{
dta.NR = int.Parse(txtnrfatures.Text);
dta.VLERATVSHTOTAL = float.Parse( textBox1.Text);
dta.BARKODI = int.Parse(dataTable.Rows[i][0].ToString());
dta.EMERTIMI = dataTable.Rows[i][1].ToString();
dta.SASIA = int.Parse(dataTable.Rows[i][2].ToString());
dta.CMIMI = int.Parse(dataTable.Rows[i][3].ToString());
dta.TVSH = int.Parse(dataTable.Rows[i][4].ToString());
dta.NENTOTALI = float.Parse(txttotali.Text);
dta.ZBRITJA = float.Parse(txtzbritja.Text);
dta.TOTALI = float.Parse(totali.Text);
dta.KOHA = DateTime.Now;
dta.KASIERI = lbluser.Text;
dta.KLIENTI = cmbklienti.Text;
dta.VLERAETVSH = float.Parse(dataTable.Rows[i][7].ToString());
dta.VLERAPATVSH = float.Parse(dataTable.Rows[i][6].ToString());
dta.NRATIKUJVE = int.Parse(lblnumri.Text);
dta.TOTALIPCS = float.Parse(dataTable.Rows[i][5].ToString());

}
The idea it that this class handle the data from form one , and use it(insert it into sql) on form two . How should I pass the object in another form, or how should I refer it. Also another question is the class populated correctly (fromtextbox, labels and datagridview )

In addition to my post earlier regarding the _data variable in form2, use the required value from it

replace
cmd.Parameters.Add(new SqlParameter("@sasia", mbushe.SASIA);
with
cmd.Parameters.Add(new SqlParameter("@sasia", _data.SASIA);

@amit, now i want the collected data to bet inserted while clicking the btn_insert(frm2)

I use this code of insertion

SqlCommand cmd = new SqlCommand("insertfaturimi", conn);
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Clear();

cmd.Parameters.Add(new SqlParameter("@nrfatures", int.Parse(txtnrfatures.Text)));
cmd.Parameters.Add(new SqlParameter("@klienti", cmbklienti.Text));
cmd.Parameters.Add(new SqlParameter("@pagesa", faturimi));
cmd.Parameters.Add(new SqlParameter("@nentotali", txttotali.Text));
cmd.Parameters.Add(new SqlParameter("@zbritje", txtzbritja.Text));
cmd.Parameters.Add(new SqlParameter("@totali", totali.Text));
cmd.Parameters.Add(new SqlParameter("@vleratvsh", textBox1.Text));
cmd.Parameters.Add(new SqlParameter("@nrartikujve", lblnumri.Text));
cmd.Parameters.Add(new SqlParameter("@kasieri", lbluser.Text));
cmd.Parameters.Add(new SqlParameter("@koha", DateTime.Now));
cmd.Parameters.Add(new SqlParameter("@barkodi", row.Cells[0].Value));
cmd.Parameters.Add(new SqlParameter("@emertimi", row.Cells[1].Value));
cmd.Parameters.Add(new SqlParameter("@sasia", row.Cells[2].Value));
cmd.Parameters.Add(new SqlParameter("@tvsh", row.Cells[4].Value));
cmd.Parameters.Add(new SqlParameter("@cmimi", row.Cells[3].Value));
cmd.Parameters.Add(new SqlParameter("@totalipcs", row.Cells[5].Value));
cmd.Parameters.Add(new SqlParameter("@vlerapatvshpcs", row.Cells[6].Value));
cmd.Parameters.Add(new SqlParameter("@vleraetvshpcs", row.Cells[7].Value));

Now mu question is how should pass the collectore method mbushe() to form use and use it like this:

instead of this

cmd.Parameters.Add(new SqlParameter("@sasia", row.Cells[2].Value));

use this

cmd.Parameters.Add(new SqlParameter("@sasia", mbushe.SASIA);

"mbushe" is the void method on first form, and the "SASIA" is a field of this method from the upper code

You can create a variable function on the second form while calling it, like below

//form2.cs
public arka_data _data;

//form1.cs
...btnClick(object sender, EventArgs e)
{
Form2 frm = new Form2();
frm._data = //pass your filled object data here
frm.ShowDialog();
}

However, there are many ways to achieve this, I shared you the minimal one.

Do let me know, if you have any further queries.

public void mbushe()
{
arka_data dta = new arka_data();
for (int i = 0; i < dataTable.Rows.Count; i++)
{......}

This method fetches the data from controls, the insert event is in second form (btninsert). I want to collect data and pass the data from form1 to form2 and use it during the insertion.

Hey

There were several ways to achieve insertion in SQL but with your seems to be incomplete.

1.
public void mbushe()
{
arka_data dta = new arka_data();
for (int i = 0; i < dataTable.Rows.Count; i++)
{......}
What is this function doing? It just fetching the data from a datatable and filling it on class object (overriding every data)

2. You might have created a seperate Data Access Layer to your project that helps you to do CRUD operations

Could your please be more clear of your question, it quite confusing...
