  • SharePoint 2013:自定义ECB菜单项的添加

    本文分别介绍了两种常用的添加ECB菜单项的方式。

    声明式创建

    这也是微软最佳实践推荐的方式。在VS中创建一个SharePoint空解决方案,并添加一个“空元素”类型的SPI。

    在Elements.xml中,定义一个CustomAction,重点关注一下其中高亮部分的属性(本例在文档内容类型的项上添加了一个菜单项,点击导航到一个自定义应用程序页面,并传递项所在的列表的Id作为参数):

    添加到Feature,并部署。效果如下:

    服务器对象模型创建

     这里会用到Feature的事件处理程序。本例同时还演示了如何指定Url,并且用对话框的方式打开。同时,还会传递网站Url,所选列表项的ID给目标应用程序页面。

    public override void FeatureActivated(SPFeatureReceiverProperties properties)
    {
        SPSite site = (SPSite)properties.Feature.Parent;
        SPWeb web=site.RootWeb;
        try{
            
                       SPList list = web.Lists["Announcements"];
                       web.AllowUnsafeUpdates = true;
                        if (list.UserCustomActions.Count > 0)
                        {
                            foreach (SPUserCustomAction action in list.UserCustomActions)
                            {
                                if (action.Name == "ECBItemCustomization")
                                {
                                    action.Delete();
                                    list.Update();
                                    break;
                                }
                            }
                        }
                        SPUserCustomAction customaction = list.UserCustomActions.Add();
                        customaction.Name = "ECBItemCustomization";
                        customaction.Location = "EditControlBlock";
                     
                        //customaction.ImageUrl = "/_layouts/15/images/demo/workflows.gif";
     
                        string cAction = @"javascript: var options = {
                                                    url: '{SiteUrl}' + '/_layouts/15/demo/page.aspx/?WorkItemID={ItemId}',
                                                    allowMaximize: false,
                                                     500,
                                                    height: 440 };
                                                SP.UI.ModalDialog.showModalDialog(options);";
                        customaction.Url = cAction;
                        customaction.Sequence = 106;
                        customaction.Title = "Demo ECB Title";
                        customaction.Update();
                        list.Update();
                        web.AllowUnsafeUpdates = false;
                        
              }
              catch{ }
     }

    相应的,要在Feature关闭时移除我们的ECB项:

    public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
    {
        SPSite site = (SPSite)properties.Feature.Parent;
        SPWeb web=site.RootWeb;
        try{
            
                       SPList list = web.Lists["Announcements"];
                       web.AllowUnsafeUpdates = true;
                        if (list.UserCustomActions.Count > 0)
                        {
                            foreach (SPUserCustomAction action in list.UserCustomActions)
                            {
                                if (action.Name == "ECBItemCustomization")
                                {
                                    action.Delete();
                                    list.Update();
                                    break;
                                }
                            }
                        }
                        
                        web.AllowUnsafeUpdates = false;
                        
              }
              catch{ }
    }

    为了看最终效果,添加了一个demopage.aspx应用程序页面。接收url参数,然后显示相应的通知标题。代码比较简单,就不贴了。部署看效果:

    注意:与SharePoint 2010的ECB不同的是,SharePoint 2013的ECB会忽略ImageUrl这一属性。因为从前面的图中也可以看出,2013的ECB项左侧都是不带图标的。
