dfpitt Hide related list table headers in VF Email Template, if related list is empty
Hello,
I have an email template that shows information from a custom object and from a related list to that custom object. I want to be able to hide the table headers whenever the related list has no records. I have tried using <apex: outputpanel rendered...> but it has n't worked, as I haven't been able to get the size of the list, so that if the outputpanel is rendered when the size is greater than 0.
Any ideas would be greatly appreciated.
I had some trouble implementing your suggestion a while back and I put this on hold.
I was able to implement it today via another route.
I created a summary field in the parent object that counts the number of records in the related list (Count_RelatedList__c) and then in the VF Email template, I use Rendered="{!relatedTo.Count_RelatedList__c >0}"

This sounds very much like something I was doing a while ago (albeit in visualforce pages). I wrote up a blog post explaining how at:

You should be able to create the custom components for use in visualforce email templates in much the same way.
Hi Bob,
thanks for your reply.
a couple of questions:
- I would have to create a Controller specific to my related list, just like the example one you posted, right?(ListIteratorExampleController)
- How would I bring in the controller into the email? Would I use an <apex:page>?
I actually have 4 related list that I want to include in the emai and only show if they have any information.
I think you'll need a controller per list, or higher level controller that converts the related list ot a list of strings.
You can include custom components in visualforce email templates, and these have custom controllers backing them. There's more details at:
