private void dataGridView3_CellClick(object sender, DataGridViewCellEventArgs e)

{
if (e.RowIndex == -1) return; //check if row index is not selected (The index must not be negative)

{
// gets the row index
DataGridViewRow row = this.dataGridView3.Rows[e.RowIndex];
// checks if cell value is not null
if (row.Cells[1].Value != null)
{
// variable str is the order number to be cancelled
ibClient.ClientSocket.cancelOrder(Convert.ToInt32(row.Cells[1].Value)); // cancels the order
// this will change the color of the background of cell 8
//row.Cells[8].Style.BackColor = System.Drawing.Color.Red;
// removes the row from the grid
dataGridView3.Rows.RemoveAt(row.Index);
}
else
{
// pop up message of nothing in order id cell coloumn
MessageBox.Show("no ID number in ID cell ");
}
}
}
