Hello,

RadCodeBlock should be used when you have server code blocks placed within the markup (most often some JavaScript functions accessing server controls). RadCodeBlock prevents the server error:
System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
For additional information please review this help article. 

All the best,
