Changing ContentTemplate based on ListBox selection

Question

I have a Listbox and a Border in a StackPanel similar to the following:

Answer 1

You can toggle the ContentTemplate using a DataTrigger as follows.
Note, that I am binding an ObservableCollection to a simple object (Thing) with one property called Name, and am I binding the Content of the ContentControl to the SelectedItem in the ListBox using a ViewModel.

Here is the Thing class:

public class Thing
{
  public Thing(String name)
  {
     this.Name = name;
  }

  public String Name { get; set; }

  public static ObservableCollection GetThingList()
  {
     return new ObservableCollection(new Thing[3] {
            new Thing("People"), 
            new Thing("Animals"),
            new Thing("Cars")
        });
  }
}
