I wrote a blog about creating a list of letters that changes depending on the language / culture the website is in.
I then had a follow up reply from Anders with a Gist that he had created and this code works in .Net Core but not in .Net Framework and since this was going to be used in an Umbraco 8 site, I needed to adjust things a bit.
Here is the code that worked for me in Umbraco 8 and .Net Framework
| @using Umbraco.Core.Composing | |
| @using Site.Core.Localisations; | |
| @{ | |
| var localisation = Current.Factory.GetInstance<LocalizationService>(); | |
| } | |
| <html> | |
| <!-- this is your razor view --> | |
| <ul class="compliance-results-index"> | |
| @foreach (var letter in localisation.GetAlphabet()) | |
| { | |
| <li class="compliance-results-item __active"><a href="/" title="@letter">@letter</a></li> | |
| } | |
| </ul> | |
| </html> |
