I'm using TListView in my form (which inherits from TCustomListView) and when I change ListView style to "vsSmallIcon" the icons gets badly arranged. We found this issue ever since we ported our Code from Borland 2006 to XE4. Rest all "ViewStyle"s like vsIcon, vsList & vsReport are working fine. Did anyone faced similar issue with VCL's TlistView component? I have already tried ListView1->Arrange(arDefault) and 'AutoArrange' Icon Options but nothing seems to work for 'vsSmallIcon' TViewStyle.
I'm on Windows 7 and using RAD Studio XE4 with Update1.
Thanks,

PS: Added an image to show this issue with vsSmallIcon TViewStyle.

ListView.Arrange(arDefault);in f.i.OnCreateof your form, also be sure to haveIconOptions.AutoArrange'true' for when you're deleting an item etc.. Does it help? – Sluff
