I am trying to change the Control template on a ListBoxItem when It is selected from the ListBox. To do so, I was going to get the selected ListBoxItem from the ListBox itself, and set the control template on that. How would i go about doing this? I have tried, SelectedItem and that returns the bound object within the ListBoxItem.

You can retrieve the item container from the bound item by using the ItemContainerGenerator :

object selectedItem = listBox.SelectedItem;
ListBoxItem selectedListBoxItem = listBox.ItemContainerGenerator.ContainerFromItem(selectedItem) as ListBoxItem;

  • This works but doesn't achieve anything. The "Content" property just returns the selected item object. I don't get the actual cell in the ListBox. – Christian Findlay Jun 26 '18 at 06:00

Now you can do it with this:

ListBoxItem container = listBox.ContainerFromIndex(listBox.SelectedIndex) as ListBoxItem;

The ItemContainerGenerator.ContainerFromItem() function seems like obsolete now.

If you have set the Item Template for the ListBox then you can get it from 

UIElement item= container.ContentTemplateRoot;
