DataSet ds;

public Form1()

{

InitializeComponent();

ds = new DataSet();

ds.Tables.Add(new DataTable("Test"));

ds.Tables["Test"].Columns.Add ( new DataColumn("Quantity",System.Type.GetType("System.Int32")));

ds.Tables["Test"].Columns.Add(new DataColumn("Cost", System.Type.GetType("System.Decimal")));

ds.Tables["Test"].Columns.Add ( new DataColumn("Total", System.Type.GetType("System.Decimal")));

dataGridView1.DataSource = ds.Tables["Test"];

}

private void dataGridView1_RowLeave(object sender, DataGridViewCellEventArgs e)

{

if (dataGridView1["Quantity", e.RowIndex].Value != System.DBNull.Value && dataGridView1["Cost", e.RowIndex].Value != System.DBNull.Value)

{

int i = Convert.ToInt32(dataGridView1["Quantity", e.RowIndex].Value.ToString());

decimal j = Convert.ToDecimal( dataGridView1["Cost", e.RowIndex].Value.ToString());

dataGridView1["Total", e.RowIndex].Value = i * j;

}
