title: GridView on change of dropdown list selection
body: <p>So I have a gridview. One of the columns in the gridview has a drop down list for all rows. Is it possible to fire a method when any of the gridview drop down boxes selection is changed?</p>
  
  <p>I tried adding the onselectedindexchange for the drop down list in the item template but it did not work.</p>
  
  <p>Any ideas?</p>
  
  <pre><code>&lt;Gridview&gt;
     &lt;Columns&gt;
        &lt;asp:TemplateField&gt;
           &lt;ItemTemplate&gt;
              &lt;asp:DropDownList runat="server"&gt;
                 &lt;asp:ListItem Value="Yes"&gt;Yes&lt;/asp:ListItem&gt;
                 &lt;asp:ListItem Value="No"&gt;No&lt;/asp:ListItem&gt;
              &lt;/asp:DropDownList&gt;
           &lt;/ItemTemplate&gt;
        &lt;/asp:TemplateField&gt;
     &lt;/Columns&gt;
  &lt;/GridView&gt;
  </code></pre>
