I would suggest you to use two different columns instead of single column, this will make data entry and even less complicated for implementation.

And then handle the CellEndEdit event of your gridview. And in that event calculate and assign the value to the third column

something like
private void dataGridView1_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
int quantity,rate;
if (int.TryParse(dataGridView1.Rows[e.RowIndex].Cells["quantity"].Value.ToString(), out quantity) && int.TryParse(dataGridView1.Rows[e.RowIndex].Cells["rate"].Value.ToString(), out rate))
{
int price = quantity * rate;
dataGridView1.Rows[e.RowIndex].Cells["price"].Value = price.ToString();
}
}
