Question

It is understood that if you wish to get a container from an item in a ListBox you can use:

ListBoxItem lbi1 = (ListBoxItem)(listBox.ItemContainerGenerator.ContainerFromIndex(0));

(Source: http://bea.stollnitz.com/blog/?p=7)

Assuming the above listbox was bound to a List, how can I do the opposite? As in, what if I wanted to get the databound data in the list by using the container (lbi1 in the above example)?

Answer 1

Ok I think I have found the answer 🙂

For ListBox items or other similar ContentControls the data can be retrieved by something like:

Class data = (Class)lbi1.Content; 

For other controls, like TreeViewItems, as they are not ContentControls, the data can be retrieved by accessing the DataContext:

Class data = (Class)treeViewItem.DataContext;
