title: Populate a value in combobox dynamicly
body: <p>I have a form where user picks a Item# and gets info for the selected Item. This form got enhanced by adding another filter, using a combobox control, to select a 'warehouse'. </p>
  
  <p>I could use a lookup for the warehouse(the list is huge) to chosse a 'warehouse' but what am trying to do to query warehouse on Item# value and populate into combobox. </p>
  
  <p>Tried to attached a screen shot, unfotunately, the system doesn't let me do it.  If I need to put more details, please let me know.</p>
  
  <p>Is it doable?</p>
