[Source-VB.NET] ListView Grouping Example - idb. - Nov 15, 2011

Was pretty sure I posted this up but I guess I didn't. This example shows ListView grouping and how to collapse/expand those groups. This uses the same class that I use in the example here: https://hackforums.net/showthread.php?tid=1740204

Anyhow, always liked the look of LV grouping. Very professional in my opinion. Hope someone can put some use to this. Some of the collapse/expand code comes from somewhere out the internets but I don't have a source at the moment to give credit to. Props to whoever that intelligent fellow was.

It's not the actual grouping that people don't know... it's the collapse/expand of it. I added a screenshot of the collapsed groups so people know what I mean by that. Also, had to do some subclassing to supress the selection of all items in the group when the group header is clicked (I always thought that was annoying as shit). This is done inside of the NativeComponents class. Grouping is pretty beginner stuff though so def agree with you on that though. Either way... I'm pretty confident someone can put some use to this.

Thank you very much for this share idb. Will make many GUI's look great in the future.

Also, I'm sure you are aware but if not to stop ListView from flickering when adding many items I found this out on the interwebs..

Quote:Using vb.net, I solved this in a slightly different way. I created a new class called ffListView, which looks like this:

Code:
Public Class ffListView
Inherits ListView

Public Sub New()
Me.DoubleBuffered = True
End Sub
End Class
Then I opened the .Designer.vb of my form and changed the initialization of my listview (which is called lvOutput) to the following:

Code:
Me.lvOutput = New ffListView
and that's all I had to do - no flicker of any sort.

All that is handled already in the NativeComponents class :)

You can do it yourself, here's s the example from MSND:

Adding items to a group is just as easy.

I know how use group items in listview. The IDB's example has collapsible group (customized listview). Thanks anyways.
