I need to place my ckeditor in insert and edit templates of the detailsview. But when I open the webpage i could see that the ckeditor is not loading.

I have added the ckeditor folder and added the javascript file

 <script type="text/javascript">
     if (CKEDITOR.instances('TextBoxArticleBody')) {
         CKEDITOR.instances['TextBoxArticleBody'].destroy();
