在这里绝望的高峰期。我离开了两个星期的假期，一个工作项目几乎在发布时我已经回到了问题。
使用Visual Studio 2010，C＃用于.Net（3.5）Web项目。
我有两种形式（几乎相同）
两种表格都包含许多事件（下面提供的代码）
表单上有许多用于触发以下对象的事件
所有活动背后的代码都存在，我知道并没有改变。
我知道他们一次又一次地检查了他们，然后向相关团队的团队负责人展示了这个项目。
经过一段美好的休息后，我回到了办公室，没有一个休息时间会开火。第二种形式仍按预期运作。
我不记得在我离开之前做了任何改变，所以我不知所措。
我今天早上尝试在表单中添加一个新对象，但它不会触发
<asp:DropDownList ID = "ddlItemList"
runat = "server"
BorderStyle = "None"
BorderColor = "White"
Height = "99%"
Width = "48%"
AutoPostBack = "true"
onselectedindexchanged = "ddlItemList_SelectedIndexChanged" >
</asp:DropDownList>
后面的代码
protected void ddlItemList_SelectedIndexChanged(object sender, EventArgs e)
{
OleDbConnection con = new OleDbConnection(odbcString);
OleDbCommand cmd = new OleDbCommand();
string theLanguage = Session["Language"].ToString();
if (Session["UserEmail"] == null)
{ // Session has timed out so get the user to log back in
........
}
else
{ // Still have the session data
// Get the list of items for the item box
try
{
......
} // Try
catch (Exception ex)
{
......
} // Catch
}
}
有没有人的想法？我很感激能得到的任何帮助。

我找到了问题的根源。
我添加了一个注册来关闭一个窗口，看起来这已经禁用了表单上的所有事件。如果我删除它全部工作（除了窗口没有关闭）
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Page.ClientScript.RegisterOnSubmitStatement(typeof(Page), "closePage", "window.onunload = CloseWindow();");
}
}
删除了注册，一切正常

可能的解决方案：
答案 2 :(得分：0)
您是否可能更改了ASPX页面标题中的命名空间或某些内容，导致未正确连接的内容？部署页面的DLL版本不正确？如上所述，干净和重新部署是最好的起点。
答案 3 :(得分：0)
添加内部
<system.web>
<compilation debug="true" targetFramework="3.5"/>
</system.web>
和Rebuild项目希望它能解决你的问题
