内容类型上的事件接收器未在WikiPageLibrary上触发

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)。接下来,我为此内容类型添加了一个事件接收器(在ItemAdded和ItemAdding上)。我的问题是没有任何事件发生。 如果我将这些事件直接添加到wiki页面库,一切正常。 是否有限制/错误/技巧?

我查看了使用SharePoint Manager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查看添加到网站的内容类型,我会将此部分视为模式。

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();
    }

Thx!

我不确定,但是在将内容类型添加到列表之前,您是否可以尝试将事件接收器添加到内容类型。

我认为之前必须添加事件接收器,因为在向列表添加内容类型时,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。
