Hello,

I'm trying to make my custom attribute that extend DisplayNameAttribute to make it localized. But I cannot get the value from the languageTextManager nor from the localizationManager.

Here is my attribute for LocalizedDisplayName

using System;
using System.ComponentModel;
using System.Globalization;
using Abp.Dependency;
using Abp.Localization;
using Abp.Runtime.Session;

namespace iExpertise.Localization
{
    [AttributeUsage(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter | AttributeTargets.Method, AllowMultiple = false)]
    public class LocalizedDisplayNameAttribute : DisplayNameAttribute
    {
        private IApplicationLanguageTextManager _languageTextManager;
        private ILocalizationManager _localizationManager;
        //private IAbpSession _abpSession;
        private string _originalName;
        public LocalizedDisplayNameAttribute(string displayName)
            : base()
        {
            _originalName = displayName;
        }

        public override string DisplayName
        {
            get
            {
                if (_languageTextManager == null)
                {
                    _languageTextManager = IocManager.Instance.Resolve<IApplicationLanguageTextManager>();
                    _localizationManager = IocManager.Instance.Resolve<ILocalizationManager>();
                    //_abpSession = IocManager.Instance.Resolve<IAbpSession>();
                }
                var translation = _localizationManager.GetString(iExpertiseConsts.LocalizationSourceName,
                    _originalName);
                var translation2 = _languageTextManager.GetStringOrNull(null, iExpertiseConsts.LocalizationSourceName,
                    CultureInfo.CurrentCulture, _originalName);
                return translation;
            }
        }
    }
}

I put a breakpoint at the return translation and it results that: translation is [Task type id_Label] translation2 is null

I wanted to be sure that my key that was added in the xml file was ok, so I navigated to the languages list and see my entry and put a breakpoint inside of the EditTextModal of LanguagesController, the translation here is ok.

In PreInitialize method of Core module I have:

//Add/remove localization sources
            Configuration.Localization.Sources.Add(
                new DictionaryBasedLocalizationSource(
                    iExpertiseConsts.LocalizationSourceName,
                    new XmlEmbeddedFileLocalizationDictionaryProvider(
                        Assembly.GetExecutingAssembly(),
                        "iExpertise.Localization.iExpertise"
                        )
                    )
                );

I cannot understand why my localization is ok in LanguagesController and not in my custom attribute in Core project.

Thanks for help

    Your code seems correct. We had actually done something similar:

    public class AbpDisplayNameAttribute : DisplayNameAttribute
    {
        public override string DisplayName => LocalizationHelper.GetString(SourceName, Key);

        public string SourceName { get; set; }
        public string Key { get; set; }

        public AbpDisplayNameAttribute(string sourceName, string key)
        {
            SourceName = sourceName;
            Key = key;
        }
    }

    And this properly works and it's already included in Abp framework. To compare, can you try to use AbpDisplayNameAttribute instead of your own attribute?

    Yeah didn't know about this existing attribute

    It's working, I was tired and set a wrong key in the attribute key value :oops:

    Do you have similar attribute for required and string length attributes that can be localized ?

    Thank for the help

    No, because we had problem with localizing validation attributes. Created an issue for that: <a class="postlink" href="https://github.com/aspnetboilerplate/aspnetboilerplate/issues/1360">https://github.com/aspnetboilerplate/as ... ssues/1360</a>
