  &lt;ContentTemplate&gt;  
      &lt;asp:DataList ID="dlSecurityQuestions" runat="server" AutoPostBack="true" OnSelectedIndexChanged ="dlSecurityQuestions_SelectedIndexChanged"&gt;
          &lt;ItemTemplate&gt;
              &lt;div&gt;
                  &lt;asp:Label ID="lbl_question" AssociatedControlID="lst_question" runat="server"&gt;&lt;%# DataBinder.Eval(Container.DataItem, "QuestionName")%&gt;&lt;/asp:Label&gt;
                  &lt;asp:DropDownList ID="lst_question" runat="server" AutoPostBack="true" &gt;
                      &lt;asp:ListItem Value="0"&gt;Select a Question...&lt;/asp:ListItem&gt;
                      &lt;asp:ListItem Value="1"&gt;Select a Question1..&lt;/asp:ListItem&gt;

              &lt;/div&gt;
              &lt;div&gt;
                  &lt;asp:Label ID="lbl_answer1" AssociatedControlID="txt_answer" runat="server"&gt;Answer *&lt;/asp:Label&gt;
                  &lt;asp:TextBox ID="txt_answer" runat="server" /&gt;
                  &lt;div id="validate"&gt;&lt;/div&gt;
              &lt;/div&gt;
          &lt;/ItemTemplate&gt;
      &lt;/asp:DataList&gt;
  &lt;/ContentTemplate&gt;
  &lt;/asp:UpdatePanel&gt;  
  </code></pre>
  
  <p>I have tried most of the options which google recommends, but i am not able to do a partial postback. evry time selectedindex is changed it does a full page postback. the drop down as you can see is in a itemtemplate and is repeated.
  what do you think I am doing wrong that its not firing postback of just the update panel.   </p>
