Hi,
I guess there is no easy way to do this, but I need to be certain before give up 
I’ve been trying to make an IO-browser in my application, where all OPC-tags are shown in a template repeater with status, description, scaling etc. I have also added the possibility to edit the tags from here.
Editing of single opc-items (non-UDT) is no problem, and out of the box dynamic.
Problem occurs when the tag is part of an UDT. Since I want this to be dynamic, I need a way to retrive the OPCItemPath, with the parameter-name used in the udt-instance. Like this:
“opcserver.cpu1.{SPAddress}”.
Update:
udt.ExtendedProperties was the answer, I need to pay more attention and RTFM
