title: ASP.Net DropDownList event handler even when user selects the same item
body: <p>I have a <code>DropDownList</code> that allows users to make selections. These selections result in a table being populated. </p>
  
  <p>This all works fine when users select different values. However, I woudl like to refresh the table even when the user selects the same value. </p>
  
  <p>Does anyone know what event on the <em>ASP.Net</em> <code>DropDownList</code> that I can use for this?</p>
  
  <p>My DropDownList looks like:</p>
  
  <pre><code>&lt;asp:DropDownList ID="ddlClient" runat="server" AutoPostBack="True"&gt;
      &lt;asp:ListItem Value="1"&gt;1&lt;/asp:ListItem&gt;
      &lt;asp:ListItem Value="2"&gt;2&lt;/asp:ListItem&gt;
      &lt;asp:ListItem Value="3"&gt;3&lt;/asp:ListItem&gt;
      &lt;asp:ListItem Value="4"&gt;4&lt;/asp:ListItem&gt;
  &lt;/asp:DropDownList&gt;
  </code></pre>
  
  <p>Thanks<br>
  Alan</p>
