How to input data in multi row into datagridview

Question

Hi Everyone.

 

I got a problem when I want to input data into my second row. whenever i try to insert data,the data always appeared in the row.

here's my code...

private void btnTambahStock_Click(object sender, EventArgs e)

{

int i = 0, j = 0, k = 0, l = 1;

if (dataGridView1[i, j].Value != "")

{

j++;

}

if (txtKodeBukuStock.Text != "" && txtJudulBukuStock.Text != "" && txtPengarangStock.Text != ""

&& txtPenerbitStock.Text != "" && txtTahunTerbitStock.Text != "" && txtJlhBukuStock.Text != "")

{

dataGridView1[k, j ].Value = txtKodeBukuStock.Text;

dataGridView1[k = k + l, j ].Value = txtJudulBukuStock.Text;

dataGridView1[k = k + l, j ].Value = txtPengarangStock.Text;

dataGridView1[k = k + l, j ].Value = txtPenerbitStock.Text;

dataGridView1[k = k + l, j ].Value = txtTahunTerbitStock.Text;

dataGridView1[k = k + l, j ].Value = txtJlhBukuStock.Text;

}

else

{

//menampilkan messageBox

MessageBox.Show("Isi textBox terlebih dahulu", "Error");

}

}

 

 

I would like to get any idea about this.. thanks
