    Checking if member has accesss on content to create menu

    I am trying to render the menu based on permission from public access..

    @foreach (var primaryNavItem in primaryNavItems)
                    {
                        var isProtected = umbraco.library.IsProtected(primaryNavItem.Id, primaryNavItem.Path.ToString());
                        var loginAcces = isProtected && umbraco.library.HasAccess(primaryNavItem.Id, primaryNavItem.Path.ToString());

                        if (!isProtected || loginAcces)
                        {
                          //menu item here
                        }
                    }

    But this throws error as below from log

        System.NullReferenceException: Object reference not set to an instance of an object.

    Can you please guide me right direction. Umbraco is v7.3.1

    Few more detail: 1. Members are Identity 2 based handled customly 2. Role provider is also custom and replaced umbraco default provider using web.config

    HI aits,

    Since your are using Umbraco 7, then try have a look at the UmbracoHelper in Razor https://our.umbraco.org/documentation/Reference/Querying/UmbracoHelper/

    As you can see you have Razor code examples

    .MemberHasAccess(int nodeId, string path)

    Returns a Boolean on whether the currently logged in member has access to the page given its ID and path.

    @if(Umbraco.MemberHasAccess(CurrentPage.Id, CurrentPage.Path)){
    <h1>Welcome!</h1>
}

    .IsProtected(int pageId, string path)

    Returns a Boolean on whether a page with a given pageId and path has public access restrictions set.

    @foreach (var child in CurrentPage.Children) { 
    <h2>@child.Name</h2>
        @if(Umbraco.IsProtected(child.id, child.Path)){
            <blink>Members only</blink>
        }
}

    Hope this helps,

    /Dennis

    Hi Dennis,

    Thanks, for your direction. But I have already tried this too. Even I got the same exception, so I tried with lower level methods but still no luck.

    Hi Dennis,

    Quick question, would this be the preferred method instead?

    Umbraco.MemberHasAccess(page.Path)

    If I try to specify page.Id then Visual Studio complains that this is obsolete:

    Method 'Umbraco.Web.UmbracoHelper.MemberHasAccess' is obsolete: Use the MemberHasAccess method that only specifies path

    Hi Bijesh,

    You need to do something like this.

    @Umbraco.MemberHasAccess(page.Id, page.Path)

    Hope this helps,

    That's what I mean, when i use @Umbraco.MemberHasAccess(page.Id, page.Path) I get a message that it's obsolete.

    If I use just Umbraco.MemberHasAccess(page.Path) it seems fine and works ok.

    I'm wondering if the documentation needs updating?

    I'm using 7.3.3.

    Hi Dennis,

    One more thing, is there a way to get the roles name that is associated with a content, SO that I could check wiht current login user as I have role in session like

    @foreach (var primaryNavItem in primaryNavItems)
                {
                    var isProtected = umbraco.library.IsProtected(primaryNavItem.Id, primaryNavItem.Path.ToString());
                  var rolesAllowed=primaryNavItem.SomeMethod();

                    if (!isProtected || rolesAllowed.Contians(Session["myRole"])
                    {
                      //menu item here
                    }
                }

    Is there any way to accomplish, I really don't want to manipulate the umbraco table to check the permission for performance issue. It looks like the problem with my custom membership. So I am thinking of this approach.

    Any help could be great.

    Thanks
