Hi,

If any one have sample code to get depenedent picklist(either Schema or MetaData Api) values please let me know.It is urgent.

Thanks

Dear Khillan,

Please see the below sample code:

And also follow this link :

http://blog.deadlypenguin.com/blog/2012/07/09/dynamic-dependent-picklists-in-salesforce/


public with sharing class ProductUtils {
static public List<Product__c> getAllProducts(Boolean includeEOL) {
//This is done since the formula field cannot return a boolean
Integer currentlySupported = (includeEOL) ? 0 : 1;
 
return [
select Name
from Product__c
where Currently_Supported__c >= :currentlySupported
order by Name
];
}
 
public static List<Product__c> getAllProducts() {
return getAllProducts(false);
}
 
public static List<Version__c> getAllVersions(Id productId, Boolean includeEOL) {
Integer currentlySupported = (includeEOL) ? 0 : 1;
 
return [
select Name,
Product__c
from Version__c
where Currently_Supported__c >= :currentlySupported and
Product__c = :productId
order by Name
];
}
 
public static List<Version__c> getAllVersions(Id productId) {
return getAllVersions(productId, false);
}
}

It is hard to find depndencies but here http://titancronus.com/blog/2014/07/03/acquiring-dependent-picklists-in-apex-contd/ has written the way to do this.

I realize that I'm 3 years too late to answer the original poster, but I have developed a very concise implementation for determining the valid dependent picklist values for every controlling value.  The solution consists of a single method of about 30 lines of Apex, and I've included test code that provides 100% coverage and full functional testing (with asserts).  You can find my solution here: https://glyntalkssalesforce.blogspot.com/2018/08/dependent-picklist-values-in-apex.html

I hope this helps you -- the developer who found this forum question in a search!
