如何仅为具有特定模板 ID 的列表添加事件接收器

发布于 2024-09-29 11:17:07 字数 740 浏览 8 评论 0原文

我正在为自定义列表模板添加 ItemAdding 事件接收器。事件接收器和列表模板都是由相同的功能部署的。同样的功能还可以创建列表实例。

我遇到的问题是，该事件在部署到的站点中为每个列表项触发。 eventreceivre 的 Elements.xml 是：

<Receivers ListTemplateId="10200">
  <Receiver>
    <Name>ListEventReceiverItemAdding</Name>
    <Type>ItemAdding</Type>
    <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
    <Class>SharepoitProject.ListEventReceiver</Class>
    <SequenceNumber>10000</SequenceNumber>
  </Receiver>
</Receivers>

我不确定我做错了什么我已经或多或少地完成了此处。

I'm adding ItemAdding event receiver for custom list template. Both event receiver and list template are deployed by the same feature. Also the same feature creates List Instances.

The problem I've got is that the event is fired for each list item in site to which it was deployed. Elements.xml for eventreceivre is:

<Receivers ListTemplateId="10200">
  <Receiver>
    <Name>ListEventReceiverItemAdding</Name>
    <Type>ItemAdding</Type>
    <Assembly>$SharePoint.Project.AssemblyFullNamelt;/Assembly>
    <Class>SharepoitProject.ListEventReceiver</Class>
    <SequenceNumber>10000</SequenceNumber>
  </Receiver>
</Receivers>

I'm not sure what I'm doing wrong I've done more or less everythin from here.

我的事件接收器也有同样的问题。我尝试了ListTemplateId、ListTemplateOwner，甚至ListUrl。我知道这些设置是有效的，但它们被忽略了，并且接收器被附加到每个列表中。

我有预感，这可能与在站点范围功能中声明的事件接收器有关。 SPEventElement 的 "documentation" 似乎证实了这一点：

  switch (this.FeatureDefinition.Scope)
  {
    case SPFeatureScope.Site:
      if (this.SiteScopedReceivers())
      {
        this.UpdateEventReceiversForSite(site, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForSite(this.GetEventReceivers(site.RootWeb).GetSqlToAddEventReceiversToSite));
        break;
      }
      else
      {
        this.UpdateEventReceiversForWeb(site.RootWeb, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForWeb(this.GetEventReceivers(site.RootWeb).GetSqlToAddEventReceiversToWeb));
        break;
      }
    case SPFeatureScope.Web:
      if (this.RootWebOnly && !web.IsRootWeb)
      {
        ULS.SendTraceTag(1718513714U, (ULSCatBase) ULSCat.msoulscat_WSS_General, ULSTraceLevel.Verbose, "Event Receivers in Feature '{0}' were not activated because current web is not the root web.", new object[1]
        {
          (object) this.FeatureDefinition.Id.ToString("B")
        });
        break;
      }
      else
      {
        bool templateIdExists;
        int templateId;
        this.CheckTemplateId(out templateIdExists, out templateId);
        if (!templateIdExists)
        {
          if (this.ListUrl != null)
          {
            this.UpdateEventReceiversForList(web, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForList(this.GetEventReceivers(web).GetSqlToAddEventReceiversToList), true);
            break;
          }
          else
          {
            this.UpdateEventReceiversForWeb(web, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForWeb(this.GetEventReceivers(web).GetSqlToAddEventReceiversToWeb));
            break;
          }
        }
        else
        {
          if (this.ListUrl != null)
            throw new SPException(SPResource.GetString("ElementHasBothTemplateIdAndUrl", new object[0]));
          this.UpdateEventReceiversForListTemplate(templateId, web, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForList(this.GetEventReceivers(web).GetSqlToAddEventReceiversToList));
          break;
        }
      }
  }

对于站点范围，ListTemplateId、ListTemplateOwner 和 ListUrl 似乎被忽略特征。当我将事件接收器元素移动到 Web 范围的功能时，接收器仅正确附加到所需的列表。

I had the same problem with my Event Receiver. I tried ListTemplateId, ListTemplateOwner, and even ListUrl. I knew the settings were valid, but they were being ignored and the receiver was being attached to every list.

I had a hunch that it might be related to the Event Receiver being declared within a Site scoped feature. This seems to be confirmed by the "documentation" for SPEventElement:

  switch (this.FeatureDefinition.Scope)
  {
    case SPFeatureScope.Site:
      if (this.SiteScopedReceivers())
      {
        this.UpdateEventReceiversForSite(site, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForSite(this.GetEventReceivers(site.RootWeb).GetSqlToAddEventReceiversToSite));
        break;
      }
      else
      {
        this.UpdateEventReceiversForWeb(site.RootWeb, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForWeb(this.GetEventReceivers(site.RootWeb).GetSqlToAddEventReceiversToWeb));
        break;
      }
    case SPFeatureScope.Web:
      if (this.RootWebOnly && !web.IsRootWeb)
      {
        ULS.SendTraceTag(1718513714U, (ULSCatBase) ULSCat.msoulscat_WSS_General, ULSTraceLevel.Verbose, "Event Receivers in Feature '{0}' were not activated because current web is not the root web.", new object[1]
        {
          (object) this.FeatureDefinition.Id.ToString("B")
        });
        break;
      }
      else
      {
        bool templateIdExists;
        int templateId;
        this.CheckTemplateId(out templateIdExists, out templateId);
        if (!templateIdExists)
        {
          if (this.ListUrl != null)
          {
            this.UpdateEventReceiversForList(web, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForList(this.GetEventReceivers(web).GetSqlToAddEventReceiversToList), true);
            break;
          }
          else
          {
            this.UpdateEventReceiversForWeb(web, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForWeb(this.GetEventReceivers(web).GetSqlToAddEventReceiversToWeb));
            break;
          }
        }
        else
        {
          if (this.ListUrl != null)
            throw new SPException(SPResource.GetString("ElementHasBothTemplateIdAndUrl", new object[0]));
          this.UpdateEventReceiversForListTemplate(templateId, web, sqlcmdAppendOnly, new SPEventElement.GetSqlToUpdateEventReceiversForList(this.GetEventReceivers(web).GetSqlToAddEventReceiversToList));
          break;
        }
      }
  }

It appears that ListTemplateId, ListTemplateOwner, and ListUrl are ignored for Site scoped features. When I moved my Event Receiver element to a Web scoped feature, the receiver was properly attached only to the desired list.

当范围限定为网站时，它会针对所有列表触发。当我将解决方案范围限定为网络时，它起作用了。希望有帮助。

这让我相信您提供的列表 templateID 可能无效。
