title: If 2 dropdown showing same value on selected index change
body: <p>I have been asked question on this scenario.There are 2 dropdownlist populating same data from same table one at top and other at bottom.when Item in first dropdownlist get selected,same item is shown in second dropdownlist and second item get selected,same item is selected in first.That means it is continuous loop.How to handle this situation. Don't want to use query
  <code>select name from table where id = ddl1.selecteditem.value</code> and execute it.
  On selectedindex function of dropdownlist1,he wrote like this</p>
  
  <pre><code>ddl2.selectedItem.value = ddl.selectedItem.value
  </code></pre>
  
  <p>and second list</p>
  
  <pre><code>ddl.selectedItem.value = ddl2.selectedItem.value 
  </code></pre>
  
  <p>Does it possible to select the value from these 2 statement?I done like this,but not working.</p>
