所以，我在C＃中創建一個ASP.NET頁面。我有一個非常簡單的形式，其上有2個文本框和3個按鈕。當我點擊「提交」按鈕時，它會調用SQL Server數據庫來檢索一些信息。一旦數據被檢索，我有一個if語句來檢查一個加載的值。問題在於單擊按鈕後頁面似乎凍結，我無法再次單擊它。我仍然可以在文本框中輸入數據，但按鈕不會顯示爲LinkButton，鼠標圖標不會更改或任何內容。對於ASPX.CS頁面的代碼如下：ASP.NET頁面凍結
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using CharacterSheet.BLL;
using CharacterSheet.Data;
public partial class Login : System.Web.UI.Page
{
protected void ClearButton_Click(object sender, EventArgs e)
{
UserBox.Text = "";
PassBox.Text = "";
}
protected void SubmitButton_Click(object sender, EventArgs e)
{
PlayerController pc = new PlayerController();
Player player;
if (UserBox.Text.Contains('@') && UserBox.Text.Contains(".c"))
player = pc.GetByEmail(UserBox.Text);
else
player = pc.GetByUser(UserBox.Text);
if (player != null)
{
if (!player.Flagged)
{
if (PassBox.Text != player.Password)
{
ErrorLabel.Text = "Password does not match our records. Please retype carefully...";
player.LoginAttempts++;
if (player.LoginAttempts >= 3)
player.Flagged = true;
pc.Update(player);
}
else
Response.Redirect(SiteData.LoginMainPage);
}
else
ErrorLabel.Text = "Your account has been flagged. Please e-mail our support team.";
}
else
ErrorLabel.Text = "Unable to find user. Please retype carefully...";
}
}
而對於ASP頁面的標記代碼：
<%@ Page Title="" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Login.aspx.cs" Inherits="Login" %>
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" Runat="Server">
<style type="text/css">
.leftColumn
{
text-align: right;
}
.style1
{
width: 30%;
text-align: right;
height: 47px;
}
.style2
{
width: 70%;
text-align: right;
height: 47px;
}
</style>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
<table>
<tr>
<td class="leftColumn">

由於任何人誰可以幫助這個！ :-)
編輯：在進一步調查（註釋掉代碼行）後，我發現問題出現時，我更新「ErrorLabel.Text」。如果我不這樣做，那麼它的功能就好了......這使我很困惑......
你調試了，它在哪裏被調試？ –
嘗試調試以查找處理停止的位置。也許當你試圖讓玩家（通過名字或電子郵件）或當你嘗試更新用戶。另一個想法：嘗試提交一個不存在的用戶。頁面是否凍結或是否照常響應？ –
當提交一個不存在的用戶時它會做同樣的事情...並且它實際上並沒有凍結...頁面在最初按下按鈕後仍在運行，但按鈕沒有響應... – Jack
