Show Size of list visual force

Question

This is my VF page:

<apex:page standardController="Account">
<apex:relatedList list="Contacts" />
</apex:page>

I would like to show number of records in the related list. I´ve tried, without success, with:

{!Account.Contacts.size}

How can i accomplish this?

UPDATE: I know that i can do it in a controller extension (query contacts + size on result list) but i would like to calculate the number of record directly in the VF page.

Thanks in adavantage for any advice

Answer 1

This is very simple. You can try this code. I tested, it is working:

You need to use apex:repeat tag to get count

<apex:page standardController="Account">
    <apex:variable var="count" value="{!0}"/>
    <apex:repeat value="{!Account.contacts}">
        <apex:variable var="count" value="{!count + 1}"/>
    </apex:repeat>
    size is {!count}
    <apex:relatedList list="Contacts" />
</apex:page>

Here's a nasty workaround that works in later API versions.

It works by coercing the related items to a string and measuring the length.

(Note that standard controller related items are not just SObject lists... so treat as black box)

• Note mysteries of VisualForceArrayList
• Note reassigning variables in apex:repeat is officially unsupported

I know it's been years since this question has been asked. But I think it could help others if I answer it anyway.

Use length instead of size in your markup.

{!Account.Contacts.length}
