I have gridlines and toUseExplorerTheme enabled in virtualtreeview (DesignTime).
I would like to remove the gridlines in runtime but it seems like I'm losing the toUseExplorerTheme property. Is this a bug or did I miss something? I tried to add it back to the set/options but no luck. I have also the XP Manifest.
Here's a little bit of code:
VirtualStringTree1.TreeOptions.PaintOptions := VirtualStringTree1.TreeOptions.PaintOptions - [toShowVertGridlines]; // I lose the ExplorerTheme :/
Thank you for your help.
