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

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!)

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

An old thread...but the modern, more efficient way to do this is `Context:Pages.GetPage(Guid:<%inf_GUID%>).GetElementByName(lst_myPages).Value.Count` (where inf_GUID is the page GUID) – neil Dec 11 '14 at 14:01

<!IoRangePreExecute>
  <% lst_myPagesSize = 0 %>

  <!IoRangeList>
    <% lst_myPagesSize = lst_myPagesSize + 1%>
    <!IoRangeRedDotMode><!--[if !IE]><%lst_myPages%><![endif]--><!/IoRangeRedDotMode>  
  <!/IoRangeList>

<!/IoRangePreExecute>

I think this is the fastest way. First counter = 0. Then in the list range increment the counter (keep in mind to include the list place-holder too in that block). After that you have the value in the counter.

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 !!%>

Would be great if someone could confirm this (or, even better, come up with a proper way of finding the length!) – Bobby Jack Jul 03 '09 at 10:40
<%!! Store:listCounter !!%> gives the position on the loop (0,1,2..) – Riccardo De Contardi Nov 30 '20 at 16:29

In OpenText use this render tag to get the length of a list (name of list element: lst_Navigation):

<%!! Context:CurrentPage.GetElementByName(lst_Navigation).GetLinkedContents().Count !!%>

Context/RDObj: by ObjectLoader Context (alias: RDObj) you get access to objects of Management Server

CurrentPage: returns Page objekt from current page

GetElementByName: method from page object to get a page element by name

GetLinkedContents: returns a LinkList object

Count: returns the number of LinkList elements

@SurajBahadur Its actually the best answer. Since Object Linklist does not have a property called Value at least in OpenText version >= 11. – aLx13 Aug 27 '20 at 13:14
