I'm trying to theme the RadTreeView to change the colours of the checkboxes. Currently, the tri-state checkbox turns red when in the indeterminate state. This is quite unusual as it is different to every other tri-state checkbox style out there, and the red draws unnecessary attention.
However it seems that whatever values I set for MiddleStateCheckColor and NormalStateCheckColor are ignored. Has anyone else successfully changed the indeterminate tri-state checkbox colour?
