Make TinyMCE text area required in MVC.

Data Annotaions (validation) works the same way as it does with other fields, tinyMCE is not different.

[Display(Name = "Details:")]
[Required(ErrorMessage = "Personal Details is required.")]
[AllowHtml]
public string PersonalDetails { get; set; }
@Html.TextAreaFor(m => m.PersonalDetails)
@Html.ValidationMessageFor(m => m.PersonalDetails, "", new { @class = "error" })
@Scripts.Render("~/bundles/jquery")
"text/javascript" src="//tinymce.cachefly.net/4.0/tinymce.min.js">
"text/javascript">
tinymce.init({ selector: 'textarea', width: 500 });
