Question

I have separated my picklist values in two records types.Now I want to display all the values of my picklist on a Visualforce page, however I am unable to do so. Please help me to achieve it. Useful links and hints are much appreciated.

public with sharing class extension_user {
private String first_picklist_option = '- All -'; //first value to display in picklist
private final User user_object; //User sobject

public extension_user(ApexPages.StandardController stdController) {
    this.user_object = (User)stdController.getRecord();
}

//builds a picklist of values based upon the passed information
public List<selectOption> getPickValues(Sobject object_name, String field_name, String first_val) {
    List<selectOption> options = new List<selectOption>(); //new list for holding all of the picklist options
    if ( first_val != null ) { //if there is a first value being provided
        options.add(new selectOption(first_val, first_val)); //add the first option
    }
    Schema.sObjectType sobject_type = object_name.getSObjectType(); //grab the sobject that was passed
    Schema.DescribeSObjectResult sobject_describe = sobject_type.getDescribe(); //describe the sobject
    Map<String, Schema.SObjectField> field_map = sobject_describe.fields.getMap(); //get a map of fields for the passed sobject
    List<Schema.PicklistEntry> pick_list_values = field_map.get(field_name).getDescribe().getPickListValues(); //grab the list of picklist values for the passed field on the sobject
    for (Schema.PicklistEntry a : pick_list_values) { //for all values in the picklist list
        options.add(new selectOption(a.getLabel(), a.getValue()));  //add the value and label to our final list
    }
    return options; //return the List
}

//return the picklist options for User.TimeZoneSidKey
public List<selectOption> getTimeZones() {
    return getPickValues(user_object, 'TimeZoneSidKey', first_picklist_option);
}

//return the picklist options for User.LocaleSidKey
public List<selectOption> getLocales() {
    return getPickValues(user_object, 'LocaleSidKey', first_picklist_option);
}

}
