Hi, everyone
First sorry for my English
I need include a slidingPanel in a contentPage. I'm tried to do anything similar to http://demos.telerik.com/aspnet-ajax/panelbar/examples/applicationscenarios/slidingpanelbar/defaultcs.aspx but I have this error System.Web.HttpException: La colección de controles no puede modificarse porque el control contiene bloques de código (por ej. <% ... %>).
Any suggestion is welcome.
Thanks in advance

Hello Marcelo,
If you receive exceptions such as "System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks" you need to move the code block (i.e. <% ... %>) outside of the head tag. Please find more details about this topic here.
All the best,
