Usercontrol not allow open popup as <% %>

[Pierre]

Hi,

My solution not allow to open Popup as javascript with call the <%  %> expressions. I'm work with one Usercontrol inside masterpage. How to open showpopup for Date and Time picking as codebehind not javascript?

System.Web.HttpException: La collection Controls ne peut pas être modifiée, car le contrôle contient des blocs de code (c'est-à-dire <% ... %>).

Not workking expressions in my solution

<script type="text/javascript">
          function OnOpen1()
          {
                     <%= RadDatePicker1.ClientID %>.ShowPopup();
            var datePicker = $find("<%= RadDatePicker1.ClientID %>"); 
            datePicker.get_selectedDate();  */
         }

Hi Pierre,

Please, wrap the script in Telerik.Web.UI RadCodeBlock  to avoid this error. You can read more about that here.
