OK, Thanks.
Can I replace the textarea with richtextbox
<%: Html.TextAreaFor(model => model.Title, new { @id = "txt_words"})%>
<%: Html.ValidationMessageFor(model => model.Title) %>
like <%: Html.richtexteditorFor(model => model.Title)
Pls, now I transfere richtext data in a textarea and then store it in database how I store and retrive it directly to richtexteditor.
