[SalesForce] Translated related list label in salesforce

<apex:page sidebar="true" showHeader="false" language="ru">

The language parameter of the page decides language.

Make a getter setter variable in the controller and use userinfo to get the language or through the query and populate on the language parameter.

This method works but still need to investigate more on why for unauthenticated user it's weird! Please try in different browser where only unauthenticated user is accessing page.

In the Metadata API CustomFieldTranslation has a picklistValues field of type PicklistValueTranslation[]. It has a masterLabel and translation string.

So your package.xml for the retrieve call would be something like:

<types>
    <members>*</members>
    <name>CustomObjectTranslation</name>
</types>

You will get something like:

<?xml version="1.0" encoding="UTF-8"?>
<CustomObjectTranslation xmlns="http://soap.sforce.com/2006/04/metadata">
<!-- SNIP... -->
<fields>
    <name>LeadSource</name>
    <picklistValues>
        <masterLabel>Advertisement</masterLabel>
        <translation>Anzeige</translation>
    </picklistValues>
    <picklistValues>
        <masterLabel>Customer Event</masterLabel>
        <translation>Kundenveranstaltung</translation>
    </picklistValues>

I am trying to build a custom wizard where user can load a file and save the records. I need to check if the translated picklist values are correct and then save them back into database

You can get the translated picklist values directly in Apex without having to go via the Metadata API.

List<Schema.PicklistEntry> picklistValues = 
    SomeSobject.SomePicklistField__c.getDescribe().getPicklistValues();
for (Schema.PicklistEntry pe: picklistValues) {
    system.debug('PicklistEntry Value:' + pe.getValue() + ' Translated Label:' + pe.getLabel());
}
