SharePoint 2013:自定義ECB菜單項的添加 - Sunmoonfire－IT工程師數位筆記本

本文分別介紹了兩種常用的添加ECB菜單項的方式。

聲明式創建

這也是微軟最佳實踐推薦的方式。在VS中創建一個SharePoint空解決方案，并添加一個“空元素”類型的SPI。

在Elements.xml中，定義一個CustomAction，重點關注一下其中高亮部分的屬性（本例在文檔內容類型的項上添加了一個菜單項，點擊導航到一個自定義應用程序頁面，并傳遞項所在的列表的Id作為參數）:

添加到Feature，并部署。效果如下：

服務器對象模型創建

這里會用到Feature的事件處理程序。本例同時還演示了如何指定Url，并且用對話框的方式打開。同時，還會傳遞網站Url，所選列表項的ID給目標應用程序頁面。

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,
                                                width: 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{ }
 }

相應的，要在Feature關閉時移除我們的ECB項：

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{ }
}
