问题描述
在绝望的高度在这里。我走了度假2周的一个工作项目几乎释放点，我已经回来了问题。
使用Visual Studio 2010，C＃为一个.net（3.5）Web项目。
我有2个形式（几乎相同）
- 创建的文档和存储在数据库中的数据
- 的数据被从数据库加载和被操纵
这两种形式都包含一些事件（code供给下文）
有与用于火以下对象的一些表格上的事件
- 文本框tbPartNumber - OnTextChanged
- 列表框lstbEmailSelectFrom - OnSelectedIndexChanged
- 列表框lstbEmailSelected - OnSelectedIndexChanged
背后的code所有事件的存在，我知道没有改变。
我知道他们解雇我检查了一遍又一遍，并展示了该项目所涉及的团队的领队。
我有一个很好的休息回来后到办公室，没有休息时间的将闪光。第二种形式仍然运行按预期。
我不记得之前，我去了，所以我很茫然做任何更改。
我想今早添加一个新对象的形式，它不火或者
＆LT; ASP：DropDownList的ID =ddlItemList

边框样式=无
BORDERCOLOR =白
HEIGHT =99％
WIDTH =48％
的AutoPostBack =真
onselectedindexchanged =ddlItemList_SelectedIndexChanged＆GT;
＆LT; / ASP：DropDownList的＆GT;
背后
在code 保护无效ddlItemList_SelectedIndexChanged（对象发件人，EventArgs的发送）
{
OleDbConnection的CON =新的OleDbConnection（odbcString）;
OleDbCommand的CMD =新的OleDbCommand（）; 。字符串theLanguage =会话[语言]的ToString（）; 如果（会话[USEREMAIL] == NULL）
{//会话超时以便让用户重新登录
........
}
其他
{//还有会话数据
//获取项目列表的项目框 尝试
{
......
} //尝试
赶上（异常前）
{
......
} //捕捉
}
}
有没有人任何想法？我想AP preciate任何帮助，我可以得到的。

解决方案
我找到了问题的根源。
我又增加了一个注册关闭一个窗口，看来这已禁用表上的所有事件。如果我删除其所有的作品（从窗户外不关闭）
保护无效的Page_Load（对象发件人，EventArgs的发送）
{
如果（！的IsPostBack）
{
Page.ClientScript.RegisterOnSubmitStatement（typeof运算（页），closePage，window.onunload = CloseWindow（）;）;
}
}
删除了登记和一切运作良好。
At the height of despair here. I went away on holiday for 2 weeks with a working project almost at the point of release and I have come back to a problem.
Using Visual Studio 2010, C# for a .Net (3.5) Web project.
I have 2 forms (almost identical)
- The document is created and the data stored in a database
- The data is loaded from the database and is manipulated
Both forms contain a number of events (Code supplied below)
There are a number of events on the form that used to fire for the following objects
- Text Box tbPartNumber - OnTextChanged
- List Box lstbEmailSelectFrom - OnSelectedIndexChanged
- List Box lstbEmailSelected - OnSelectedIndexChanged
The Code behind for all events exists and I know have not been changed.
I know they fired as I checked them over and over and demonstrated the project to the team leader of the team involved.
I have come back into the office after a nice break and none of the breaks will fire. The second form still operates as intended.
I cannot remember making any changes before I went off so I am at a loss.
I tried adding a new object to the form this morning and it does not fire either
<asp:DropDownList ID = "ddlItemList"
runat = "server"
BorderStyle = "None"
BorderColor = "White"
Height = "99%"
Width = "48%"
AutoPostBack = "true"
onselectedindexchanged = "ddlItemList_SelectedIndexChanged" >
</asp:DropDownList>
with the code behind
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
}
}
Has anyone any Ideas ? I would appreciate any help I can get.

解决方案
I found the source of the problem.
I had added a registration to close a window and it appears that this has disabled all events on the form. If I remove it all works (apart from the window not closing)
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Page.ClientScript.RegisterOnSubmitStatement(typeof(Page), "closePage", "window.onunload = CloseWindow();");
}
}
Removed the registration and all works well
