The Controls collection cannot be modified.

[manoj]

Hi Team,
i am creating Multi language selection feature in Web App using Global Resources,Local Resources and bootstrap(css and Js). But I am getting the following Error while rending telerik control.

Error:
"The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)."

Aspx Code:
<% if (dirs == "ar-EG")
       { %>

 <link href="../bootstrap-arabic/css/bootstrap-arabic.css" rel="stylesheet" />

    <% }
       else
       { %>

 <link href="../bootstrap/css/bootstrap.css" rel="stylesheet" />

 <% } %>

Aspx control working good with  same code but issue occur while use telerik control.  
What is the possible way solve this issue Please suggest.

Hi Manoj,

The error you are seeing is most likely observed because you have JavaScript code that is not wrapped in a RadScriptBlock. Please ensure that all client-side code is placed inside RadScriptBlock and the error should disappear.
