[RESOLVED] ListView Group Display Problem at run-time

Hello,

I've come across a really weird problem. I was trying to see the groups in my application, but it didn't seems to work at run-time. So, I stated to develop my control in a test application. Everything works fine. So, I've tried again since I was a lot better with the control and it still doesn't work.

So, when I'm in the designer, I add group, add items and we can see them fine. But as soon as I run the application, I loose all the grouping. I've put a screenshot in attachment.

So, I was wondering what can cause that? I've tried to search information on the net, but didn't found anything? Any idea would be welcome. It's probably a setting in my project, a reference or something like that, but I've looked at everything and didn't find any anomaly.

Thanks in advance!

Hahaha, looks like posting made me thought about the problem. I'm under XNA and I'm making an editor. I just remember I had to put the attribute STAThread. So, after comparing the 2 program.cs, I found out that there was a missing line that 6-7 month ago didn't made sense to me, but now reading it, make all the sense in the world:

Code:

---

Application.EnableVisualStyles();

---

So, seems like the styles are related to the groups in the ListView.
