title: dropdownlist autopostback?
body: <p>below is my dropdownlist with autopostback true now when i select prefix1 it gives me a post back but when i select it again it doesnt. I have to select prefix2 item first and then go back to prefix1 for it to postback again. Its like as if its postbacking only with <code>SeletedIndexChange</code>.</p>
  
  <p>I need postback evrytime I choose in my dropdownlist even if its the same item:</p>
  
  <pre><code>&lt;asp:DropDownList runat="server" ID="lstFilePrefix1" AutoPostBack="True" 
       OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged"  &gt;
      &lt;asp:ListItem Text="Prefix1" Value="Prefix1" /&gt;
      &lt;asp:ListItem Text="Prefix2" Value="Prefix2" /&gt;
      &lt;asp:ListItem Text="Prefix3" Value="Prefix3" /&gt;
      &lt;asp:ListItem Text="Prefix1 and Prefix2" Value="Prefix1 and Prefix2" /&gt;
      &lt;asp:ListItem Text="Prefix2 and Prefix3" Value="Prefix2 and Prefix3" /&gt;
  &lt;/asp:DropDownList&gt;
  </code></pre>
