In this blog, we are going to discuss about how to add and delete the custom action in site menu using csom.

Introduction

In this blog, we are going to learn how to add and delete the custom action in the site menu using CSOM. Custom actions are linked or custom menu items that we can add to the SharePoint UI. This can be added to a site or the list/library menu.

Add Custom Action to site menu

Here we have added the custom action in the site menu. Please copy the below code snippet to add the custom action in the site menu.

using System;
using System.Collections.Generic;
using System.Security;
using Microsoft.SharePoint.Client;
namespace CustomAction {
    class Program {
        static void Main(string[] args) {
            string userName = "[email protected]";
            string password = "Password";
            string siteUrl = "https://contoso.sharepoint.com/sites/SiteName";
            SecureString securePassword = new SecureString();
            foreach(char c in password) {
                securePassword.AppendChar(c);
            }
            var cred = new SharePointOnlineCredentials(userName, securePassword);
            using(ClientContext ctx = new ClientContext(siteUrl)) {
                try {
                    ctx.Credentials = cred;
                    Web oWeb = ctx.Web;
                    ctx.Load(oWeb);
                    UserCustomActionCollection userCustActionColl = oWeb.UserCustomActions;
                    UserCustomAction objUserCustAction = userCustActionColl.Add();
                    objUserCustAction.Location = "Microsoft.SharePoint.StandardMenu";
                    objUserCustAction.Group = "SiteActions";
                    objUserCustAction.Sequence = 101;
                    objUserCustAction.Title = "Site User Custom Action";
                    objUserCustAction.Description = "This description appears on the Site Actions menu.";
                    objUserCustAction.Url = "https://contoso.sharepoint.com/sites/SiteName/SitePages/myPage.aspx";
                    objUserCustAction.Update();
                    ctx.Load(oWeb, webSite => webSite.UserCustomActions);
                    ctx.ExecuteQuery();
                    Console.WriteLine("Successfully added user Custom Action");
                } catch (Exception e) {
                    Console.WriteLine(e);
                }
            }
        }
    }
}

                foreach(char c in password) {

                }
                var cred = new SharePointOnlineCredentials(userName, securePassword);
                using(ClientContext ctx = new ClientContext(siteUrl)) {
                        try {
                            ctx.Credentials = cred;
                            Web oWeb = ctx.Web;
                            ctx.Load(oWeb);
                            UserCustomActionCollection userCustActionColl = oWeb.UserCustomActions;
                            ctx.Load(userCustActionColl, userCustomActions => userCustomActions.Include(userCustomAction => userCustomAction.Title));
                            ctx.ExecuteQuery();
                            foreach(UserCustomAction objUserCustomAction in userCustActionColl) {
                                if (objUserCustomAction.Title == "Site User Custom Action") {
                                    objUserCustomAction.DeleteObject();
                                    ctx.ExecuteQuery();
                                    Console.WriteLine("Successfully deleted user Custom Action");
                                }
