Button click control c#

Apr 9 2024 6:54 AM

My code for button

Button btn = (Button)sender;
var itemAndPrice = btn.Text;

int sno = dataGridView1.Rows.Count + 1;
string nazivartikla = itemAndPrice.Split('-')[0].ToString();
double cijena = Convert.ToDouble(itemAndPrice.Split('-')[1].ToString());
string exists = "";
NazivArtiklaTextBox.Text = nazivartikla;
Provjera_stanja();
Sifra_i_Podgrupa_robe();

foreach (DataGridViewRow g1 in dataGridView1.Rows)
{
    if (g1.Cells[2].Value.ToString().Trim() == itemAndPrice.Split('-')[0].ToString().Trim())
    {
        exists = "y";
        g1.Cells[3].Value = Convert.ToInt32(g1.Cells[3].Value) + 1;
        g1.Cells[5].Value = Convert.ToDouble(g1.Cells[3].Value) * Convert.ToDouble(g1.Cells[4].Value);
    }
}

if (exists != "y")
{
    dataGridView1.Rows.Add(sno, SifraTextBox.Text, nazivartikla, 1, cijena, cijena);
}

double[] columnData = new double[dataGridView1.Rows.Count];
columnData = (from DataGridViewRow row in dataGridView1.Rows
              where row.Cells["kolicina"].FormattedValue.ToString() != string.Empty
              select Convert.ToDouble(row.Cells["kolicina"].FormattedValue)).ToArray();
kolicinalabel.Text = columnData.Sum().ToString("0.00");

double[] columnData2 = new double[dataGridView1.Rows.Count];
columnData2 = (from DataGridViewRow row in dataGridView1.Rows
               where row.Cells["ukupno"].FormattedValue.ToString() != string.Empty
               select Convert.ToDouble(row.Cells["ukupno"].FormattedValue)).ToArray();
ukupnolabel.Text = columnData2.Sum().ToString("0.00");
UkupnobezpdvLabel.Text = columnData2.Sum().ToString("0.00");
label15.Text = columnData2.Sum().ToString("0.00");


double ukupno;
if (!double.TryParse(ukupnolabel.Text, out ukupno))
{
    // ... report problem to user ...
    return;
}
double lab3;
if (!double.TryParse(label3.Text, out lab3))
{
    //... report problem to user ...
    return;
}
label4.Text = (ukupno * lab3 / 100.0).ToString("0.00");


dataGridView1.Refresh();
