What is the correct way to put multiple controls inside update panel? : <p>I have one registration form which contains 3 to 4 dropdown controls and 2 datepickers and now when dropdown controls value are selected(selectedindex change are fired)
then i dont want my page to postback.</p>

<p>I have use update panel to stop this behaviour of post like below:</p>

<pre><code>&lt;asp:UpdatePanel ID="UpdatePanel1" runat="server"&gt;
        &lt;ContentTemplate&gt;

      &lt;%--Update Panel for date picker%&gt;
      &lt;asp:UpdatePanel ID="UpdatePanelDatepicker" runat="server"&gt;
                    &lt;ContentTemplate&gt;
                      &lt;telerik:RadDatePicker ID="rdpDate1" runat="server"&gt;
                      &lt;/telerik:RadDatePicker&gt;
                    &lt;/ContentTemplate&gt;
      &lt;/asp:UpdatePanel&gt;

       &lt;%--Update Panel for Dropdown--%&gt;
       &lt;asp:UpdatePanel ID="updatepaneldata" runat="server"&gt; 
                      &lt;ContentTemplate&gt;
                     &lt;telerik:RadComboBox ID="ddlCountry" runat="server"&gt;
                      &lt;/telerik:RadComboBox&gt;
                    &lt;/ContentTemplate&gt;
      &lt;/asp:UpdatePanel&gt;


  &lt;/ContentTemplate&gt;
    &lt;/asp:UpdatePanel&gt;
