title: Keyboard focus to list box items in WPF
body: <p>I am having a list box, and its item template is having one check box. 
  Now, when I click on the check box in the listbox, it sets the checked status of the check box. If I use keyboard "Space" key, I cannot change the checkbox state. </p>
  
  <p>Note: Keyboard is shortcut is working once I set focus to the check box by clicking it. </p>
