共享点错误 [英] Sharepoint errors

问题描述

我已经创建了一个.net Web部件并将其部署在共享点站点上.预览时，共享点将引发错误，提示预览Web部件时发生错误"

I have created a .net web part and deployed it on the sharepoint site. When I preview it, the sharepoint throws up an error saying "An error occured when previewing the Web Part"

Web部件中的代码如下

The code in the web part is as follows

        Dim myweb As Microsoft.SharePoint.SPWeb = Microsoft.SharePoint.WebControls.SPControl.GetContextWeb(Context)
        'Dim mylist As Microsoft.SharePoint.SPList = myweb.Lists(System.Configuration.ConfigurationSettings.AppSettings("BedList").ToString())
        Dim mylist As Microsoft.SharePoint.SPList = myweb.Lists("{80F6F320-E1F5-42EB-A2FB-895EAE00F589}")
        Dim items As Microsoft.SharePoint.SPListItemCollection = mylist.Items

        For Each item As Microsoft.SharePoint.SPListItem In items
            returnString = returnString + "<br/>" + item("Status").ToString() + " For " + item("Title").ToString + "<br/>"
        Next

有人知道为什么这行不通吗?我无法掌握所引发的执行力. 任何帮助都是很好的

Does anyone know why this would not work. I can not get hold of the execption thrown. any help would be greatful

推荐答案

首先，您应该通过更改web.config中的以下内容来使您的异常可见

First you should make your exceptions visible by changing the following in the web.config

CallStack = true

CallStack = true

    <SafeMode MaxControls="200" CallStack="true" DirectFileDependencies="10" TotalFileDependencies="50" AllowPageLevelTrace="false">

CustomErrors = Off

CustomErrors = Off

<customErrors mode="Off" />

然后您将看到真正的异常

Then you will see the real exception

您还可以尝试使用以下代码获取当前网站:

You can also try obtain the current web using the following code:

Dim myweb As Microsoft.SharePoint.SPWeb = SPContext.Current.Web

尝试获取列表时，其他问题可能与listId或ListName错误有关.

Other problem could be related with wrong listId ou ListName when you try to obtain the list.
