    Question Refresh of WPF controls

    Attached is a small simple VB.NET app that loads a Listview with some items. I want the items to appear as I add them but right now they do not appear until all of the items are added. What do I have to do to get an added item to appear as I add them? Thank you

    I would recommend is using an ObservableCollection and bind the listbox to the collection.

    That way you can add/remove items to the collection and the listbox will automatically display the changes. Also, you probably want to set it up in the Loaded event instead of ContentRendered event.

    I don't code in VB, but here's a link to a sample:
