How to refer to a parameterized data page from html?
Hello !
We are modifying a section developed in html (A non-auto generated section in a Pega framework). It has a dropdown control sourced from the prompt list of the corresponding property. Now, we want to dynamically populate the dropdown. We want to populate it using a parametrized data page. How do we do so in html?

You can reference the Parameter page properties using the prefix 'Param' like this:
<p:r n="Param.MyText" m="literal"/>
So for example : I have created an Activity which sets a Parameter, then performs a 'Show-Stream' of a "Rule-Obj-HTML" file which contains the Pega Tag above:
When I run the Activity; it shows the Parameter is used:

Oops: I misread your question - you need call a Parameterized Data Page; rather than access the Parameter Page.
I'll look into this and get back shortly !
(there is a special syntax using square brackets I believe - but I need to double-check)

Mmmh: I just tried using this Expression (using an OOTB Data Page) on PRPC72 in a Pega Tag:
D_pxOperatorDetails[OperatorId:"Admin@gcs"].pyUserName
, but it seems these are not allowed in this context, I get:
Section 'MyHTMLRule' execution error on page 'pyTempPage' of class 'OBQ6DY-GCS-Work'. : The reference D_pxOperatorDetails[OperatorId:"Admin@gcs"].pyUserName is not valid. Reason: declare page parameters not supported by PropertyReference
So I guess you will have do a Property-Set to another Property before hand to capture the value; and then reference that Property (or Param) ?
