I have been doing some research and this seems to be not possible unless I start digging into InterOperabilty, i.e PInvoke and what not which is not really my kettle fish. I am re posting this question as I want to know if anyone has managed to do this yet?
I use .png for all my images and get a professional to provide my images so I know the images come with the best quality most appropriate formats.
It seems the standard tree view control does not support a background image directly a such neither does it allow its background colour to be set to transparent? Anyone got any ideas on these two?
If you’re willing to use a third-party library take a look at http://objectlistview.sourceforge.net/cs/index.html – note however that it’s GPL. It’s easy to set the background images there.
