title: What event handler to use for ComboBox Item Selected (Selected Item not necessarily changed)
body: <p><strong>Goal:</strong> issue an event when items in a combobox drop down list is selected.</p>
  
  <p><strong>Problem:</strong> Using "SelectionChanged", however, if the user choose the same item as the item is currently being selected then the selection is not changed and therefore this event will not be triggered.</p>
  
  <p><strong>Question:</strong> What other event handler(or other ways) I may use to issue an event regardless of the selected item is changed or not as long as the mouse clicked on that item and that item is being selected.</p>
  
  <p>(Clarification: Problem is how to trigger "something" when the same item is being selected again. No duplicates in the drop down list. Scenario: first time select item 1,close drop down. And then again, open drop down box and select item 1 when some function are triggered.)</p>
  
  <p><strong>Solution</strong>: for now there seems to be no straight-forward solution to do this. But according to each individual project, there can be ways to work around it. (Please update if there are indeed good ways to do this). Thanks.</p>
