Add data to a list box from a dropdown
<p>I have a listbox (listBox) and a dropdown list(dropDown).  I want to be able to select an item from the dropDown and add them to the listBox.  I have looked everywhere for this but all I ever see is adding data from a datasource instead of a dropdown.  I want this to be dynamic so the listBox is populated based on the a user selected in the dropDown</p>
