WinForms ListView

[realJSOP]

Is it possible to use callbacks (like in the old days with C++/MFC) to display listview items? Or how about an observable collection that tells a listview that its data has changed? Anything like that?

in vb.net to get the items in listview take this

dim name as string
dim ind as integer

for each items as listviewitem in listview1.items
' here you get the name of the item
name = items.text ' or items
'here your get the index
ind = items.index

next items

Using INotifyProprtyChanged with an obseravable collection is a good option. Have a look here - http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/c86df936-853f-452f-ad98-7d2ac53958ff[^]. Hope this helps.

One way to achieve this would be to have your collection implement INotifyCollectionChanged (if using ObservableCollection is out of bounds), and use a mediator class to monitor the changes. Obviously you'd want to use INotifyPropertyChanged for individual items in the collection.

Would using a DataGridView be a better option? I don't want anything fancy - I just need the listview to update items that have changed (possibly hundreds of items changing every 2 or three seconds or so). BTW, this isn't a WPF application...

This is not a WPF application.

You can use the VirtualMode in list view. http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.virtualmode.aspx[^] This way you can specify your own content in call back events.

Will these links help you? Both use INotify. http://blog.spencen.com/2009/03/04/inotifypropertychanged-via-extension-methods.aspx[^] http://stackoverflow.com/questions/638859/c-winforms-how-to-update-listbox-items-with-inotifypropertychanged[^]

I don't know that DGV would be a better choice. The fact that the listview supports virtualisation is a big plus. BTW - I figured it wasn't WPF.
