Question

I’m used to the old Winforms way of doing things. Apparently WPF ListViews are full of… XmlElements? How would I do something like disabling a ListViewItem?

foreach (XmlElement item in this.lvwSourceFiles.Items)
{
   //disable?

}

ListView is an ItemsControl. ItemsControl.Items does not return the child controls – it returns the items – that is, objects that you have added to the ListView, either directly, or via data binding. I guess in this case you have bound your ListView to some XML, right?

ListViewItem (and other classes like it – e.g. ListBoxItem for ListBox) is called an “item container”. To retrieve an item container for a given item, you should do this:

ListView lv;
...
foreach (object item in lv.Items)
{
   ListViewItem lvi = (ListViewItem)lv.ItemContainerGenerator.ContainerFromItem(item);
}
