Can we have, Backend / Frontend Different Languages?

hello all
i look for a way that i have, English Language for my admin panel and Persian Language for my store.
that mean i need , store customers just see Persian language(don't have combo box or key for change language).
how can i do it?
Regards,

Assuming that your website is currently in Persian, you can create a new language (English) and then remove all public resources from the language pack. Then export this language pack and after that import it over your Persian language. The remaining admin resources (English) will override the ones in Persian and you will have your administration in English while your public store will remain in Persian.
If your website is currently in English you should proceed in the opposite way - create a Persian language, remove all admin resources, export the language pack and then import it over the English language, so the public resources in Persian will override the ones in English.

Does anyone have another idea?

Nop-templates solutions sounds like the right way to do it but if your default language is Persian you could try commenting out the language selector for the public store in Views\Shared\Header.cshtml

I haven't tried it but I think that would prevent the customers from selecting a different language but still leave you the option to switch it to English on the admin side.

Another option would be to add a second url to the store (i.e. admin.yourstore.com) and use the multistore function to limit the admin language to this new store.

But in that case you would probably want to implement some redirect rules as well to redirect the public store to the official url.

I think the first proposal with leaving all "Admin" resources in english is better.

In my case, I have the Portuguese language package installed and would like the admin in English.

I've downloaded the English xml file, and then I'm suppose to delete all the public resources?
As xml files are a big mess, can you give an example of what to delete and what to leave for the admin to be in English?
