Hi Thomas,

with below you can check the logged user of umbraco back end page.

 var ticket = new HttpContextWrapper(HttpContext.Current).GetUmbracoAuthTicket();
            if(ticket != null)
            {
                var userName = new HttpContextWrapper(HttpContext.Current).GetUmbracoAuthTicket().Name;
                if(ApplicationContext.Current.Services.UserService.GetByUsername(userName) != null)
                {
                    //Here you can add Your Logic to get node based on user role.
                }
            }

Hope this will help you.

Hi Mehul, 

Thank you for your reply, but it wasn't quite what I was hoping for. My emphasis was more on the "when the page is requested" part of the question. Sorry for not being too clear on that. 
I've tried to do the userrole-check on the umbracoPage.Load event, but I can't get it to fire when I surf to https://www.mysite.com/umbraco#/content/content/edit/2538, for example.

So I'm not sure where I can do the User check to prevent the user from surfing to this page.

I hope you (or anyone else) can help me with this.

Hi Thomas,

Can I know how you have restricted user to display content pages?

Because I am not able to restrict particular user to particular content pages from content tree.

I am just able to set start not of the Content tree.

Hi Thomas,

when you hit this link in another browser https://www.mysite.com/umbraco#/content/content/edit/2538

will you get the login prompt ? if yes then can you please check which user name and password you entered

because once you set the permission for any "node" to one user , the umbraco it self the restrict the access for this node to other user.

Administer user can access all node so it might be possible that you had enter in umbraco with administer privilege

and then you had try to access this url and you got the access.

share your steps if i am getting wrong

@Mehul

Apart from creator of the node, there are some other things that need to be hidden for certain users. There are some users that ARE allowed to see other writers' content, so hiding it for the current user seemed like a good idea. 
So I'm not really setting actual permissions for child node, but hiding it from the content tree.  (See my answer to Urvish below)

I'll definitely take a look at setting the permissions, but for the time being, do you have any idea whether there's an event I can register to that fires when i go to the link?

@Urvish

I'm just taking everything the user shouldn't see out of the content tree before rendering it.

TreeControllerBase.TreeNodesRendering += TreeControllerBase_TreeNodesRendering;

public static void TreeControllerBase_TreeNodesRendering(TreeControllerBase sender, TreeNodesRenderingEventArgs e)
        {

            var currentUmbracoUser = sender.UmbracoContext.Security.CurrentUser;
            var currentUser = UserManager.GetUserBaseByUmbracoUserId(currentUmbracoUser.Id);
            List nodesToDelete = new List();

            var aliasesToCheck = new List()
aliasesToCheck.Add("Newsitem"); // add whatever content types you want to check

            var contentIds = e.Nodes.Where(
                    x =>
                        x.AdditionalData != null &&
                        x.AdditionalData.ContainsKey("contentType") &&
                        x.AdditionalData["contentType"] != null &&
                        aliasesToCheck.Contains(x.AdditionalData["contentType"].ToString()))
                    .Select(x => Convert.ToInt32(x.Id))
                    .Distinct();
            if (contentIds.Any())
            {
                var itemContents = sender.Services.ContentService.GetByIds(contentIds);

                foreach (var contentId in contentIds)
                {
                    var content = itemContents.FirstOrDefault(x => x.Id == contentId);
                    if (content == null) continue;

                    if (content.CreatorId != currentUmbracoUser.Id)
                    {
                        nodesToDelete.Add(contentId);
                    }
                }
            }

            e.Nodes.RemoveAll(x => nodesToDelete.Contains(Convert.ToInt32(x.Id)));
        }

(cleaned this code up a bit, hope i didn't take too much out)

is working on a reply...
