title: How to get the previous item on DropDownList before OnSelectedIndexChanged fires the event
body: <p>How would I get the previous item on <code>DropDownList</code> before <code>OnSelectedIndexChanged</code> fires the event?</p>
  
  <p>Example: I had a <code>DropDownList</code> that has names as its items ("John", "Mark"). By default the <code>SelectedIndex</code> is "John". Upon changing its index and selecting "Mark" the event <code>OnSelectedIndexChanged</code> will be triggered. When I use <code>ddlName.SelectedIndex</code> it will return only the index for "Mark" which I want to get is the index of "John".</p>
