  Since migrating to Delphi 12 & Raize 8.0 I noticed that the checkboxes aren’t drawing anymore.
  
  At design-time they do appear, but at runtime when I generate the items, it no longer draws the checkboxes. I’m not doing any custom drawing.
  
  I was wondering if there was a known issue around this? Thanks!
  
  (as an aside i tried uploading an image to show the issue but it kept denying any format I tried to attach)

  Hi,
  Are you able to reproduce the issue in a test project? If so, please send the source code (zipped up) to support@raize.com and I’ll take a look.

  I think I have narrowed it down. The existing project has the “Project Options” –> Application –> Manifest –> “Enable Runtime Themes” unchecked.
  
  I can replicate it any project. Confirmed it worked in KSVC 7.0 & Delphi 12
  
  Sample attached: https://filebin.net/256hmfmmo0d820t8/ksvc8_checktree_runtime_themes_Project1.zip
  – Project1.dpr, Project1.dproj, Unit1.dfm, Unit1.pas
  
  Will send to support email as well. Thanks!

  I’m struck with the same problem.
  
  However i noticed something is changed in the default TTreeview.
  
  If you use TTreeview (not the Raize version) and want to use the partial checkbox you have to check cspartial in Checkstyles.
  When you do that and compile the checkboxes don’t show anymore….
  
  Since the TrzCheckTree also uses Partial it is hit with the same problem.
