C#, VB.NET, ListView Groups are not showing

Listview not showing groups? This could be your problem.

  • I have done everything to display groups but they refuse to display!
  • Cannot see groups in listview
  • Listview has groupings but no groups at runtime
  • listview does not show groups
  • listview not showng groups

Call it at the beginning of your App, this will only effect people who decide to add this to an older app in most cases.

I ripped my hair out for a while before finding this in the documentation. Grats googlers I did the work for you.

ListView groups are available only on Windows XP Home Edition, Windows XP Professional, Windows Server 2003 when your application calls the Application..::.EnableVisualStyles method. On earlier operating systems, any code relating to groups has no effect and the groups will not appear. For more information, see ListView..::.Groups.

p.s. - Another possibility is you are viewing in details but do not have a column added.
p.p.s. - Another possibility is you do not have listview1.showgroups = true.
p.p.p.s. - You can also set this in the properties rather than calling it. (Picture below p.p.p.p.s.)
p.p.p.p.s. - If you are running anything older than XP, Server 2003, etc you cannot view visual styles and are screwed until you update.

Thanks Technage - I had missed Application.EnableVisualStyles();
in Program.cs.
