ListView subitem editing

[K_F]

Hi... Somewhere over here there was a ListView (detail/report mode) example where you could edit a subitem.
I know of using a modified edit box laid over the cell, but I'm sure this example shows an easier method !!

I've tried search.. but nothing has popped up. I vaguely remember it.. but if anyone has it or a link... pleeezze 

Thanks

Send LVM_EDITLABEL to the listview control ;)

If I not mistaken, you can only edit the Item with LVM_EDITLABEL, not the subitem, as you'll need an Item and SubItem number to locate it.

http://www.masmforum.com/board/index.php?topic=17551.0 is an example i had that allowed editing of the subitems to display dropdown combos, dropdown lists or editboxes. Hope that helps, there is a couple other links in that old forum post that points to a few sources i referred to whilst making my own example.

Thanks Fearless.. I think that looks similar to what I'm thinking... I read through it  :t

Problem solved,... quite neatly actually..
I used a hidden EditBox.. which I just repositioned (and Zordered) depending where you clicked in the List View
Just must do the Edit Box proc to transfer the changes back to the Item or subItem, and do the column width changes as well.

I'm going to tidy this thing up (add all the other functionality), and put it up as an example..

Here an extended version of the ListView editing with an edit box.

I could go on forever.. but digressing would take too much time so I cut it at this point.
It's not perfect, but you might be able to use the idea..

It's an EasyCode project with the exe in the Debug folder.
