Mandatory related item
Posted: 06 Jan 2017
Hi , I couldn't find any information about that: is there any way to make a related item mandatory. Let's say: if the user checked the box then he should incert at least one related item.
Hi Katy,
You can check if the related items is empty via JavaScript before the submission in the 'onsubmit' handler:
if (fd.relatedItems(0).data('ctx').ListData.Row.length > 0) {...}
