  When a user changes a theme, the themed treeview hot background paints using the color of the previous theme’s C1TreeView\Palette\Colors\ControlBackColor path
  
  
  
  In this example the theme was changed from Office2013HighContrast to Office2010Blue

  Since themed backgrounds are frequently brushes, intercepting ApplyNodeStyles wont help.

  Many themes C1TreeView\TreeViewStyles\Hot\BackBrush background brushes are transparent, yet backrounds are painted slightly greyed.

  Is there a way to force nodes to display properly once the theme is changed? None of the
  
  Thanks,

  PS Any news on the Sluggish Treeview With Only 300 Nodes problem? (I get the feeling it has to do with storing images in a treelist which used to slow down the Ribbon Menu and Tabs controls) It would be great to directly set the images used by the checkboxes and expand collapse.

  Hello,

  We could not observe both the issues at our end using 4.0.20173.282. If you are using any older version ,we suggest you to please update using C1Live. If still the issues occurs, could you please modify the uploaded application, so that we could test at our end and help you further: https://www.dropbox.com/s/vjglimtp1muk7zy/TreeViewStyle.zip?dl=0
  
  Also, regarding slow loading of C1TreeView, the development team is currently working over this case. We will update you once it is updated.

  Thanks,
