Does anyone know how to get filtering to work for UDTs on the Tag Browse Tree component? I want to filter on tags that contain a specific string. using the components builtin filter function, I can filter on tag name, but that doesn’t help because if I have a tag with, for example, “PV” as a child element, all i can access is PV; I don’t know what the path to this item is, so i lose all my PVs, which defeats the purpose because you can’t historize a UDT, only its child elements.
So i also went as far as populating the historized tags’ Documentation metatdata with the tag path, but when I access this from the filter function, the returned property is blank, even though i can see it has populated correctly inside the designer’s tag browser.
Any ideas how I can make the component do what i need?
I also tried using a treeview to create a custom tag browser, but this cam with other issues (no drag drop which i need (from component to trend chart), very complicated coding required for my specific project etc), so i’d prefer avoiding this line of investigation.
