Hi Pablo,

From memory, there are some examples if ListView in Torry <www.torry.net>

Do a search, also look in tVCL - List and Tree Views for samples and
in Tips - search on Listview and sort

If you can't find anything, please let me know, and I can post a sample

I am leaving the house for a few hours, but will be back in about 8 hours

I have tried many examples, so I must doing something wrong .
I am working on the virtuallistview example of turbo explorer (the same
of delphi 7) an I need to click on the column header and
sort the list for that column like the Window$ explorer.

Thanks

What examples have you tried? In what ways did they not work? What were
you expecting to happen, and what happened instead?

Pablo,

Here is some code you can try

It is the Unit and DFM files for a very simple test I was doing

It should come up and work as it is, but if not, then add in some more
data

Cheers,

Frank
