Hi, after following the guide on setting the colour of tasks on data binding, which worked great, we have noticed an issue. If we have something like the following tree
Level 1
-- Level 2
---- Level 3
---- Level 4
Level 5
Level 6
If level 3 and 4 have a background colour set to say purple.... its working fine, but if we collapse Level 2, Level 5 and 6 have the background colour changed to purple as Level 3 and 4 would have been.
From looking at the source code, Levels 5 and 6 seem to replace the details in the rows for Level 3 and 4 but don't change the styling used. What we need to do is on collapsing the level, we need to repaint the rows to refresh the styling.
Is there any event we can use to detect the expanding / collapsing function so i can call another function which repaints the displayed tasks? I've included 2 screenshots which demonstrate the behaviour.
