How do I determine the length of a list in RedDot?

Question

I have a page with a list element attached. How do I determine the number of items in that list? Can use render tags, asp, or any other technique (so long as it works!)

Answer 1

Apparently, the only way to do this is to loop through the list, counting each item, e.g.

<reddot:cms>
<foreach itemname="testList"
         object="Context:CurrentPage.Elements.GetElement(lst_myPages).Value"
         countername="listCounter">
</foreach>
</reddot:cms>

The length is then available as:

<%!! Store:listCounter !!%>

Answer 2

Reading the render tags documentation I believe it may be possible to do this in a nicer way

So getting the list Element using this

Context:CurrentPage.Elements.GetElement(lst_myPages).Value

The Value property should return a page collection for list items so you should be able to do

Context:CurrentPage.Elements.GetElement(lst_myPages).Value.Count
