Hi,
This issue was referenced all the way back in 2017 in this post for Win Forms, but it appears it was never actually resolved; only a workaround was provided. I don't think this workaround will work for me, however, because I am binding to the RtfDataProvider in xaml and therefore it makes the changes to the document string before I am able to do a manual replacement of "rtf1" where it only had "rtf" for the version tag before. While changing the tag after the fact will fix the issue of it not being recognized in the other software we use, it still causes bloat because of the fact that it most cases it over triples the amount of raw text in the returned string when the textbox does not properly apply the rtf version tag.
Below is an example of the greatly enlarged amount of data before and after this error occurs:

If there is a way that I can use the workaround in that post to prevent this bloating of the data while still using my current setup with bindings, I would be happy to do so, but as it is I don't think that's the case. It seems like this is clearly a bug and something that should have a real fix on the control and not a workaround after all this time, but if that's not the case and it was left as is for a reason, I'd be happy to hear that reason.
Thanks in advance for the help.
Is there a workaround for this or is this a bug that you will fix?
Hi,
I found a bug when drag&dropping selected tree nodes (extended multi-selection) when the tree is virtualized. Items that never got into view are missing from the Payload Manager Data object. If virtualization is off, works as expected.
Please see modified sample for demonstration. I added 200+ items to League A -> Division A. Select the first item, quickly scroll by dragging vertical scrollbar to the bottom of the list and extend selection to the whole list. Then perform drag and drop. Note, not all items were moved.
Also, the drag visual helper moves and updates very very slowly when dragging hundredths of objects. In our application, we have thousands of objects, which makes it unusable
Thank you for a quick fix.
Tomas.
