ex. I have grid1 with items and grid2 that is null, so I want to add items from grid1 to grid2, but not duplicate the rows just increment quantity of the same item , I hope I'm more clear now :)

After adding row you can assign values to the cell whichever you want. The following code will increment the value of first row and first column with 1. You have to make sure there is a value in the particular cell before adding it.

dataGridView1.Rows[0].Cells[0].Value = (int)dataGridView1.Rows[0].Cells[0].Value + 1;

yes I have solved this myself, take a look here :

C#

private void insertitem_toBill()
{
    DataGridViewRow row = new DataGridViewRow();
    // create cells and fill them from dgv1 data
    row.CreateCells(this.dgvBill, ID, NameTxtBox.Text, outPriceTxtBox.Text, PriceTax.Text, QuantityTxtBox.Text, TaxTxtBox.Text);

    if (dgvBill.Rows.Count == 0)
    {
        this.dgvBill.Rows.Add(row);
    }
    else
    {
        bool SAME = false;
        for (int i = 0; i < dgvBill.Rows.Count; ++i)
        {
            if (dgvBill.Rows[i].Cells[0].Value.ToString() == ID)
            {
                dgvBill.Rows[i].Cells[4].Value = (Convert.ToDouble(dgvBill.Rows[i].Cells[4].Value) + Convert.ToDouble(QuantityTxtBox.Text)).ToString();

                SAME = true;
            }
            try
            {
                decimal value1 = Convert.ToDecimal(dgvBill.Rows[i].Cells[3].Value);
                decimal value2 = Convert.ToDecimal(dgvBill.Rows[i].Cells[4].Value);
                dgvBill.Rows[i].Cells[6].Value = value1 * value2;
            }
            catch{}
        }
        if (SAME == false)
        {
            this.dgvBill.Rows.Add(row);
        }
    }


    //calculating sum of rows
    decimal sum = 0;
    for (int i = 0; i < dgvBill.Rows.Count; ++i)
    {
        sum += Convert.ToDecimal(dgvFatura.Rows[i].Cells[6].Value);
    }


    TotalTxtBox.Text = sum.ToString();
    SearchProductTxtBox.Text = "";
}
