我有一個填充了從數據庫檢索的值的表單。該表單有一個提交按鈕,應該在點擊數據庫時更新數據庫中的相應字段。更新表格保留原始值
問題是無論我做什麼值都不會在數據庫中更新。我正在使用一個存儲過程,並檢查了兩次,它工作正常,我也嘗試了硬編碼插入值的技巧 - 也可以。
我的猜測是,一旦該字段從Page_Load上的數據庫填充,即使我改變它的值,它的值仍然存在。如何解決此問題,以便我可以使用相同的表單來檢索和更新數據?
protected void Page_Load(object sender, EventArgs e)
{
lblMsg.Visible = false;
string bookingid = Request.QueryString["bookingid"];
Booking b = BookingAccess.GetBooking(Int32.Parse(bookingid));
if (b != null)
{
var start_date_formatted = ((DateTime)b.StartDate).ToString("dd-MM-yyyy");
var end_date_formatted = ((DateTime)b.EndDate).ToString("dd-MM-yyyy");
pet_name.Text = b.PetName;
species.Text = b.Species;
start_date.Text = start_date_formatted;
end_date.Text = end_date_formatted;
}
}
protected void btnEditBooking_Click(object sender, EventArgs e)
{
string bookingid_raw = Request.QueryString["bookingid"];
int bookingid = int.Parse(bookingid_raw);
var start_date_formatted = DateTime.ParseExact(start_date.Text, "dd-MM-yyyy", null);
var end_date_formatted = DateTime.ParseExact(end_date.Text, "dd-MM-yyyy", null);
string pet_name = "a";
string species = "b";
lblMsg.Visible = true;
string msg = BookingAccess.UpdateBooking(bookingid, pet_name, species, start_date_formatted, end_date_formatted);
if (msg == null)
lblMsg.Text = "Updated booking details successfully!";
else
lblMsg.Text = "Error -> " + msg;
}
請添加您的代碼。並確保你的郵件沒有填充字段。 – MikeSmithDev
