                {
                    Book bookModel = Mapper.Map<AddEditBookViewModel, Book>(model);
                    db.books.Add(bookModel);
                    db.SaveChanges();
                }
                return view("index");
        }
}

How can i post ckeditor html value to action to save or edit?

Answer 1

Forms post back the name/value pairs of its successful form controls and the ModelBinder binds your model based on those values. Your model contains a property named BookDescription but you have overwritten the name attribute generated by the TagHelper (which is name="BookDescription" ) and given it name="editor1" which is not the name of a property in your model.

Remove the name="editor1" attribute so that you input is

<textarea id="editor1" asp-for="BookDescription" class="form-control"></textarea>

As a side note, the TagHelper also generated id="BookDescription" by default, and there is no need to overwrite that attribute either. You could also delete the id="editor1" attribute and the script would then be

CKEDITOR.replace('BookDescription');
