Unfortunately this is not currently possible. It is a common request we know about and have on the list, and it should become available in Version 5.21 (less than a month from now); if not (unlikely but possible) then into the subsequent version.

quick follow up question - can the daItemDialog be used to return more than one item, perhaps in a collection? if not, is there another function that can?
thanks!
thanks!

thank you for your quick reply!
i changed the "Specific Version" property to "False" for all of the OPCLabs assembly references and rebuilt my app. my app is now allowing me to traverse the entire hierarchy, and select items (leafs) along the way.
thank you for your support with this issue.

Thsi could be because the assemblies of a precise version are being referenced (Visual Studio does this for assemblies that it finds in the GAC).
You can either remove all QuickOPC assembly references from your project and them add them anew, or simply select them, and in the Properties window, set the "Specific Version" property to False.

i uninstalled the older version of QuickOPC, then downloaded and installed the newer version from your website. when i tried to rebuild my app, the build failed with these errors:

it looks like old QuickOPC elements are being looked for (Version=5.20.507.10) - how do i eliminate these old references? i tried to clean the build before rebuilding it, but that did not seem to help.
thank you again for your assistance!

It is quite likely that this is fixed in the recent build (5.20.1016.1), posted on our Web site today. Can you please install it, rebuild your app, and re-test?
More info: We have addressed a problem where no node elements were returned, that occurred when following conditions were fulfilled: 1) filter for both leaves and branches was used (this is also the case with DAItemDialog), 2) the server supported DA 3.0 but not DA 2.0, and 3) no leaves were present at the parent node.
Interestingly, we have found this in internal testing some weeks ago and fixed it, but the fix has not been made public. It is quite possible that you ran into precisely the same thing. Please let me knwo if this resolves the issue.
Kind regards,
Zbynek Zahradnik

the server supports OPC-DA 2.05A; does not support 3.0.
in the hierarchy screenshots, the selected item is the first one encountered when traversing the hierarchy from the root down. so i believe the answer to your question is yes - there are no items (leafs) at the root level.
thank you. please let me know if you have any other questions.

One more question, sorry - does the server support OPC-DA 2.0, OPC-DA 3.0, or both?
Many thanks

Thank you. Is the true number of leafs (items) on the root level zero - i.e. no error in behavior there? (I could not see this from any of your pictures).
