Submitting a multipart AJAX form with CKEditor textarea

OK, the subject of this post is pretty niche, but that’s why I am posting about it because I do it so little I’d only forget about it for the next time!

With ASP.NET MVC if you want to allow a file upload on a form submitted by AJAX then you have to intercept the form submit event and do the submit it yourself via Javascript, rather than using MVC’s helpers. This is detailed in this useful Stackoverflow answer: How to do a aspnet mvc ajax form post with multipart form data

What the post doesn’t mention (as it wasn’t asked for!) was that if your form contains an instance of the popular rich text editor CKEditor then this code alone will not transfer the data the editor contains to the form. I think this must be because the CKEditor is waiting for the submit event to be triggered before it does the copy into the field.

It took a bit of digging, as I have not had to look at the CKEditor API before, but if you take the code from the above link as a start point, then add the following code to somewhere between the event.preventDefault() call and the ajax() call, it seems to work OK.


            for (instance in CKEDITOR.instances) {
                CKEDITOR.instances[instance].updateElement();
            }
