Access Rights for Properties

Hi All

I am using IMetadataAware to restrict access to certain properties on content types, although when using an example i found from Linus it doesnt seem to work if the property is located in the SystemTabNames.PageHeader tab

The code i am using is as follows :

    public class PropertyEditRestrictionAttribute : ValidationAttribute, IMetadataAware
    {
        public PropertyEditRestrictionAttribute(string[] allowedRoles)
        {
            AllowedRoles = allowedRoles;
        }

        public string[] AllowedRoles { get; set; }

        public void OnMetadataCreated(ModelMetadata metadata)
        {
            foreach (string role in AllowedRoles)
            {
                if (EPiServer.Security.PrincipalInfo.CurrentPrincipal.IsInRole(role))
                {
                    return;
                }
            }
            metadata.IsReadOnly = true;
        }

        public override string FormatErrorMessage(string name)
        {
            return "You do not have access to change " + name;
        }

        protected override ValidationResult IsValid(object value, ValidationContext validationContext)
        {
            var contentData = validationContext.ObjectInstance as IContentData;
            if (contentData == null)
            {
                //This attribute only handles instances of IContentData.
                return ValidationResult.Success;
            }
            if (!contentData.Property[validationContext.MemberName].IsModified)
            {
                return ValidationResult.Success;
            }
            return base.IsValid(value, validationContext);
        }

        public override bool RequiresValidationContext
        {
            get
            {
                return true;
            }
        }

        public override bool IsValid(object value)
        {
            foreach (string role in AllowedRoles)
            {
                if (EPiServer.Security.PrincipalInfo.CurrentPrincipal.IsInRole(role))
                {
                    return true;
                }
            }
            return false;
        }
    }

And to restrict at Property Level i am doing

        [PropertyEditRestriction(new string[] { "WebEditors" })]

Just to confirm when i use on any other property not in that specific tab it works just fine. Any Help would be appreciated

Also for some bonus points is their anyway i can completely restrict access to SystemTabNames.PageHeader or Hide it ? Via admin mode i tried setting access right to administer only and it took no effect

Cheers

is this possible we can use dynamicall with out [PropertyEditRestriction(new string[] { "WebEditors" })] this method, this is should be like hard code. we can to handle this in CMS

Maybe you can hide the property if placed in PageHeader?

if (metadata.GroupName == SystemTabNames.PageHeader)
{
    metadata.ShowForEdit = false;
    metadata.ShowForDisplay = false;
}

Oh, btw, you can hide the default page header with this editor descriptor:

[EditorDescriptorRegistration(TargetType = typeof(string))]
[EditorDescriptorRegistration(TargetType = typeof(string), UIHint = "previewabletext")]
[EditorDescriptorRegistration(TargetType = typeof(bool))]
[EditorDescriptorRegistration(TargetType = typeof(bool?))]
[EditorDescriptorRegistration(TargetType = typeof(AccessControlList))]
public class HideAllPageHeaderProperties : EditorDescriptor
{
    private static IEnumerable<string> _pageHeaderPropertyNames = new[]
    {
        "iroutable_routesegment",
        "icontent_name",
        "PageExternalURL",
        "PageVisibleInMenu",
        "PageTypeName",
        "ACL"
    };

    private static IEnumerable<string> _allowedRoles = new[]
    {
        "CmsAdmins",
        "Administrators"
    };

    public override void ModifyMetadata(ExtendedMetadata metadata, IEnumerable<Attribute> attributes)
    {
        base.ModifyMetadata(metadata, attributes);

        if (IsDefaultPageHeaderProperty(metadata.PropertyName) && !_allowedRoles.Any(EPiServer.Security.PrincipalInfo.CurrentPrincipal.IsInRole))
        {
            metadata.ShowForEdit = false;
            metadata.ShowForDisplay = false;
        }
    }

    private static bool IsDefaultPageHeaderProperty(string propertyName)
    {
        return _pageHeaderPropertyNames.Any(name => name.Equals(propertyName, StringComparison.OrdinalIgnoreCase));
    }
}

I've come upon a similar problem recently. Though it seems like the "ACL" property has been hidden since this answer. Any idea how to change change the GroupName of the "ACL"?
