Update Contact Mailing Address with Account Billing Address on Custom Button

March 28, 2015

Requirement: On Account Detail Page is there is a Custom Button named Copy Address, When We click on this button then Billing Address of Account record is updated in all Contacts of that Account in Mailing Address.

Solution : There are 3 solution
1) First one is write the trigger and invoke at custom button
2) Call javascript code on Custom Button
3) Invoke Web service on Custom Button.

I am explaining 3rd .

Firstly Create a Apex Class:

Class Name : UpdateContactAddress

global class UpdateContactAddress {

webservice static String processDetails(String accID){

List<Account> lstacc =[select id,BillingCity,BillingCountry,BillingState from Account where ID =:accID limit 1];
system.debug('acc====='+lstacc);
List<Contact> lstofcont =[select id ,MailingCity,MailingCountry,MailingState,MailingPostalCode,MailingStreet
from contact where AccountID =: accID];

system.debug('lstofcont ====='+lstofcont);

List<Contact> Updatelstofcon = new List<Contact>();
If(lstacc!=null && lstacc.size()>0)
{

if(lstofcont!=null && lstofcont.size()>0)
{
for(Contact objCon :lstofcont )
{
// objCon .accountId = acc.Id;
system.debug('lstofcont =====dddd');

// For demo i m populating one fiield but similar you can update other fields , those field must be in query
objCon.MailingCity = lstacc[0].BillingCity;

/*objCon.MailingStreet = lstacc[0].BillingStreet;

objCon.MailingState = lstacc[0].BillingState;

objCon.MailingCountry = lstacc[0].BillingCountry;

objCon.MailingPostalCode = lstacc[0].BillingPostalCode;

objCon.MailingCity = lstacc[0].BillingCity; */

Updatelstofcon.add(objCon);

}
}

}

system.debug('Updatelstofcon=====dddd'+Updatelstofcon);

if(Updatelstofcon!=null && Updatelstofcon.size()>0)
{
update Updatelstofcon;
}
return null;


}
}
