I am sure many of us aware of this error :
System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).
at System.Web.UI.ControlCollection.Add(Control child)
at Telerik.Web.SkinRegistrar.RegisterCssReference(Page _page, Control _control, String _url)
My case is i have a master page used as template.
Now there is another page that has an user control in it which has the rad treeview in it.
To narrow down the problem i have just added a rad treeview with rad script manager to the user control
This user control is placed in an aspx page which has a master page set for it.
now While trying to access this page i am getting the same error.
Can anyone help me in this respect.
I need it urgently.
Thanks for your help in advance.
