我为 wiki 页面库创建了一个新的内容类型。我通过代码将此内容类型添加到库中(接口不允许这样做)。接下来,我向此内容类型添加了一个事件接收器(在 ItemAdded 和 ItemAdding 上)。我的问题是没有触发任何事件。如果我将此事件直接添加到 wiki 页面库中,则一切正常。有限制/错误/技巧吗?

我使用 SharePoint Manager 查看了附加到库的内容类型,在他的架构中缺少事件接收器的部分......我知道应该有类似的内容:

<XmlDocuments>
    <XmlDocument NamespaceURI="http://schemas.microsoft.com/sharepoint/events">
      <spe:Receivers xmlns:spe="http://schemas.microsoft.com/sharepoint/events">
        <Receiver>
          <Name>
          </Name>
          <Type>1</Type>
          <SequenceNumber>10000</SequenceNumber>
          <Assembly>RssFeedWP, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f6722cbeba696def</Assembly>
          <Class>RssFeedWP.ItemEventReceiver</Class>
          <Data>
          </Data>
          <Filter>
          </Filter>
        </Receiver>
        <Receiver>
          <Name>
          </Name>
          <Type>10001</Type>
          <SequenceNumber>10000</SequenceNumber>
          <Assembly>RssFeedWP, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f6722cbeba696def</Assembly>
          <Class>RssFeedWP.ItemEventReceiver</Class>
          <Data>
          </Data>
          <Filter>
          </Filter>
        </Receiver>
      </spe:Receivers>
    </XmlDocument>

如果我使用 SPM 查看添加到站点的内容类型,我会在架构中看到这部分。

这是我的代码:

   public override void FeatureActivated(SPFeatureReceiverProperties properties)
    {
        using (SPWeb web = (SPWeb)properties.Feature.Parent)
        {
            // create RssWiki content type
            SPContentType rssFeedContentType = new SPContentType(web.AvailableContentTypes["Wiki Page"], 
                                                web.ContentTypes, "RssFeed Wiki Page");

            // add rssfeed url field to the new content type
            AddFieldToContentType(web, rssFeedContentType, "RssFeed Url", SPFieldType.Note);                
            // add use xslt check box field to the new content type
            AddFieldToContentType(web, rssFeedContentType, "Use Xslt", SPFieldType.Boolean);                
            // add xslt url field to the new content type
            AddFieldToContentType(web, rssFeedContentType, "Xslt Url", SPFieldType.Note);

            web.ContentTypes.Add(rssFeedContentType);
            rssFeedContentType.Update();
            web.Update();

            AddContentTypeToList(web, rssFeedContentType);
            AddEventReceiversToCT(rssFeedContentType);
            //AddEventReceiverToList(web);
        }
    }

   private void AddFieldToContentType(SPWeb web, SPContentType ct, string fieldName, SPFieldType fieldType)
    {            
        SPField rssUrlField = null;
        try
        {
            rssUrlField = web.Fields.GetField(fieldName);
        }
        catch (Exception ex)
        {
            if (rssUrlField == null)
            {
                web.Fields.Add(fieldName, fieldType, false);
            }
        }
        SPFieldLink rssUrlFieldLink = new SPFieldLink(web.Fields[fieldName]);
        ct.FieldLinks.Add(rssUrlFieldLink);
    }

   private static void AddContentTypeToList(SPWeb web, SPContentType ct)
    {
        SPList wikiList = web.Lists[listName];
        wikiList.ContentTypesEnabled = true;
        wikiList.ContentTypes.Add(ct);
        wikiList.Update();
    }

   private static void AddEventReceiversToCT(SPContentType ct)
    {
        //add event receivers                
        string assemblyName = System.Reflection.Assembly.GetExecutingAssembly().FullName;
        string ctReceiverName = "RssFeedWP.ItemEventReceiver";

        ct.EventReceivers.Add(SPEventReceiverType.ItemAdding, assemblyName, ctReceiverName);
        ct.EventReceivers.Add(SPEventReceiverType.ItemAdded, assemblyName, ctReceiverName);
        ct.Update();
    }

谢谢 !

我不确定,但您能否在将内容类型添加到列表之前尝试将事件接收器添加到内容类型。

我认为必须先添加事件接收器,因为在将内容类型添加到列表时,内容类型不会直接添加到列表中,而是将其副本添加到列表中。因此,当您将内容类型添加到列表时,还没有事件接收器。
