Is there a way to modify a value in a listview after it is added

[thedesolatesoul]

This is something elementary, but I just want confirmation whether it can be done.
It seems that there is no way to modify a value of a label in a listview, once it has been added.
I was hoping there could be a way, where I could assign a string ByRef, so when I change the value of the string, it changes in the listview automatically.
Thanks!

You could dump all the info in the ListView to a list, change what you need to change and then re-populate the ListView again.

That may be a good idea if the listview is not visible, but if it is, then the scroll position will change and it will look weird to the user.

This can be very quick, I use a similar method to filter entries in a list of over 2000 items and it's almost instant.

You could use a ScrollView, then you have the whole control on it.
You can modify any entry and set the scroll position.

Best regards.

You can set the scroll position so the edited field re-appears in the window, if I remember correctly it will be at the top of the visible window (unless it's less that one screen full from the top or bottom).

Yes, I now plan to use a scrollview.
I wanted to create a download list (like in the browser), which is also expandable/collapsible. and shows the current progress of all the downloads.
Initially I thought I could get away with using a listview (and using cunning indentation to indicate hierarchy), but now I think a scrollview is the way to go.

stevel05,
My download progress timer is 0.5 seconds, and updated the progress (and hence listview) every 1/2 a second. I think the UI will be too jerky with the scrollposition jumping around.

Yes that sounds more appropriate considering what you actually want it to do.
