Hi all,
I want to implement a listview with editable subitems and I assume the
easiest way is to overlay a textbox over the item to be edited.
With this in mind I have come up with:
Using fullrowselect=t rue in the listview
Private Sub ListView1_ItemS electionChanged (ByVal sender As Object, _
ByVal e As System.Windows. Forms.ListViewI temSelectionCha ngedEventArgs) _
Handles ListView1.ItemS electionChanged
Dim t As New TextBox
Me.Controls.Add (t)
t.Location = e.Item.Position
t.BringToFront( )
End Sub
Unfortunately item.position only enables me to get the position of the first
column. How can I obtain the x position of the subitem that was clicked.
I have searched google, but the only examples I can find are in C++ which I
can't make any sense of.
Thanks,
Martin.

I have found this VB6 example, but I can't figure out how to convert it to
..net, can anyone help me.
Thanks

Hi Martin,
I have come up with something similar myself, but I can't see how to easily
adapt it to work with scrolling of the listview, so I would definitely be

Here is my version anyway, which retrieves the text from the any of the 6

I have changed my objective a bit. Since detecting a scroll event in a
Listview requires me to subclass the Listview (MS simply forgot to raise a
scroll event, although it is built in the API) I am going to do it right.
I'm building a subclass of the Listview that allows any kind of control
(checkbox, combobox, datetimepicker, textbox) to be added as subitem.
If you're interested I will publish the code on my site when I'm done.

Although my solution works in the context in which I am using it, I am well
aware that it isn't very efficient and would be very interested in seeing
how you approach the problem, as I am a newbie programmer and what you are
suggesting is well beyond my capabilities at the moment.
If you want to email me the link to your site you can send it to mvhorn@remove_t his_bit.ntlworl d.com or post it here instead.
Kind regards,
