读取SharePoint 2010列表时出现“项目不存在"错误 [英] 'Item Does Not Exist' error reading SharePoint 2010 List

问题描述

我在SharePoint 2010中有一个列表.如果我以编程方式(通过自定义Webpart)将项目添加到列表中，则以后可以阅读这些项目并将其显示在其他Web部件中.但是，如果尝试读取通过Web界面添加的列表项，则会在Webpart中收到以下错误:

I have a list in SharePoint 2010. If I add items to the list programmatically (via a custom webpart), I can later read those items and show them in other web parts. However, if I attempt to read a list item added through the web interface, I get the following error in my webpart:

该项目不存在. 您选择的页面包含一个不存在的项目.它可能已被另一个用户删除.0x81020016

Item does not exist. The page you selected contains an item that does not exist. It may have been deleted by another user.0x81020016

奇怪的是，在调试器中，我看到正确读取了列表项.我正在把剩下的头发拉出来.

The weird part is, in the debugger, I see that the list item is properly read. I'm pulling what's left of my hair out over this one.

有什么想法吗?

这是任何关心的人的答案:

Here's the answer for anyone who cares:

我这样称呼我的页面-mywebpage.aspx?id = 1，其中id = 1是我希望Webpart显示的列表中项目的ID.由于只有Microsoft知道的某些原因，在查询字符串中使用'id'是不可以的.因此，我将参数名称更改为"lid"，现在一切正常.

I was calling my page like this - mywebpage.aspx?id=1, where id=1 was the id of the item in the list I wanted my webpart to display. For some reason known only to Microsoft, using 'id' in the query string is a no-no. So I changed the param name to 'lid' and now everything works like I would expect.

推荐答案

好吧，我想我已经找到了.我这样称呼我的页面-mywebpage.aspx?id = 1，其中id = 1是我要显示Webpart的列表中项目的ID.由于只有Microsoft知道的某些原因，在查询字符串中使用'id'是不可以的.因此，我将参数名称更改为"lid"，现在一切正常.

Well, I think I've found it. I was calling my page like this - mywebpage.aspx?id=1, where id=1 was the id of the item in the list I wanted my webpart to display. For some reason known only to Microsoft, using 'id' in the query string is a no-no. So I changed the param name to 'lid' and now everything works like I would expect.
