您必須在GridView的RowDataBound事件中編寫代碼。

我張貼，供大家參考示例代碼，自己嘗試一下

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     Label lblPrice = (Label)e.Row.FindControl("lblPrice"); 
     Label lblUnitsInStock = (Label)e.Row.FindControl("lblUnitsInStock"); 

     decimal price = Decimal.Parse(lblPrice.Text); 
     decimal stock = Decimal.Parse(lblUnitsInStock.Text); 

     totalPrice += price; 
     totalStock += stock; 

     totalItems += 1; 
    } 

    if (e.Row.RowType == DataControlRowType.Footer) 
    { 
     Label lblTotalPrice = (Label)e.Row.FindControl("lblTotalPrice"); 
     Label lblTotalUnitsInStock = (Label)e.Row.FindControl("lblTotalUnitsInStock"); 

     lblTotalPrice.Text = totalPrice.ToString(); 
     lblTotalUnitsInStock.Text = totalStock.ToString(); 

     lblAveragePrice.Text = (totalPrice/totalItems).ToString("F"); 
    } 
}
