}

Still one question :
1) Is this still possible with the KryptonTreeview ?
TreeViewChannels.BackColor = KryptonManagerMain.GlobalPalette.GetBackColor1(PaletteBackStyle.PanelAlternate, PaletteState.Normal)
TreeViewChannels.ForeColor = KryptonManagerMain.GlobalPalette.GetContentShortTextColor1(PaletteContentStyle.LabelNormalPanel, PaletteState.Normal)

@Tom : it would be great, with the colored background it would allow us to have the treeview we can see in office 2010. So +1 for the possibility.

Feature requests are not possible, but here a customdrawn request: The posibility to draw the background over the full width, to mimic the outlook treeview?!
