Custom picklist or lookup

Hi,

 I am trying to create a wizard that will create a case based on user input to the pages. 

On the first page the user selects the account from a lookup.  On the second screen, I only want to allow the user to pick a contact that is associated with the account selected on the first screen.  I implemented a lookup but it shows all contacts.  Is there a way to show only the contacts on the account selected; or, if not, how can I implement a select list with only the associated contacts?

 

Thanks,

Lloyd

If you wanted to use a picklist in place of the standard lookup field you could include the apex:pageBlockSectionItem tag in your visualforce page. It may look something like this:

<apex:pageBlockSectionItem> <apex:outputLabel value="Contacts" for="c"></apex:outputLabel> <apex:selectList id="c" value="{!Custom_Field}" size="1" title="Contact"> <apex:selectOptions value="{!contactlist}"></apex:selectOptions> </apex:selectList> </apex:pageBlockSectionItem>

 

The "{!Custom_Field}" piece is the field where the selection is stored. Then you'll need to have add something like the following to your extension or custom controller:

 

public List<selectOption> getContactlist() { List<selectOption> options = new List<selectOption>(); //new list for holding all of the picklist options options.add(new selectOption('', '- None -')); //add the first option of '- None -' in case the user doesn't want to select a value or in case no values are returned from query below for (Contact contacts : [SELECT Id, Name FROM Contact WHERE AccountId = 'XXXXXXXXXXXXXXXXXX']) { //query for Contact recordsassociated to your account Id options.add(new selectOption(contacts.Id, contacts.Name)); //for all records found - add them to the picklist options } return options; //return the picklist options }

 

You will need to adjust the query portion of the code above to suite your specific needs but this should at least get you pointed in the correct direction.

Thank you Greg.  I was working in the right direction but couldn't quite get it.

Thanks again.
