Hi all,
I have a treeview and because I subclass the treeview and
allow multiple selection to be done on the treeview, I
have a problem changing the background color of the
treeview.
The problem is that after I multi-select the treenodes,
and I try to change the background color of the treeview,
those treenodes that have been multi-selected before still
maintain the previous background color. The rest of the
background change prefectly, only the bounds of those
previously selected nodes do not change.
I know that I can loop through all the nodes and change
the background color of the nodes but I don't understand
why this happens? Since everytime I reset the background
color of the nodes, I use the value treeView.BackCo lor.
Any suggestions will be greatly appreciated!
Thank you in advance.
regards,
Sean

I haven't tried this myself, so no guarantees, but it might be as simple as
invalidating the rectangle that represents the client area of the treeview.
Worth a try?

I'd like to be able to give a treeview in my application a nice smooth
gradient as a background image, but I'm having trouble doing this. Webpages
that I've seen so far seem to suggest using the BackgroundImage property, but
this does not seem to work. I'm using C# Express 2008.
Does anybody here have any solutions?
