Fire selectedindexchange event on button click for dropdown
<p>i change dropdown list with button click like this: </p>

<pre><code>ddl.selectedIndex+=1
</code></pre>

<p>my dll has a selectedindexchange event which is not firing if index changed through button. Is it a normal behavior? Should I create separate method and call it right after the <code>ddl.selectedIndex+=1</code> or there's a better way?</p>
