    Our Project Migrated  from .Net 3.5 with Telerik 2009.2.701.35  version  to  .Net 4.5 with Telerik 2013.1.417.45 version.

    After successful migration when we run the application we get the following exception but we could not get proper solution or reasons for the exception in any forums.

    Issue is causing in the situation where multiple usercontrols are present inside  a page/usercontrol.  

    Hence to replicate this issue, we created an isolated demo project based on our application.    The demo contains working Page as well Error producing page.  It has a Master Page, Page, Parent UserControl, Child UserControls.   If a Page contain only one usercontrol it is working well. However if it contains several Usercontrols, there comes a problem, especially when a usercontrol have several child usercontrols inside.

    Hello Meenakshi,

    The presented error is rather generic and could occur in various cases. Therefore it will be best if you cold open a  regular support ticket and send us the isolated test application which demonstrates the issue. Thus we will be able to debug it locally and advise you further.
