title: DropDownList.SelectedIndex sets to 1
body: <p><a href="https://stackoverflow.com/a/81379/11582004">&quot;DropDownList.SelectedIndex = -1&quot; problem</a></p>
  <p>I used the above solution to set my DropDownlist and it is working as expected. But I have noticed <strong>an intermittent bug</strong>, where after the Insert Item at index 0 using below code<br>
  <code>myDropDownList.Items.Insert(0, new ListItem(&quot;Please select&quot;, &quot;&quot;));</code><br>
  The <strong>myDropDownList.SelectedIndex is set to 1</strong></p>
