Question

I’m using ASP.net MVC C# in Visual Studio Web Dev. I have a couple of textareas which are populated with data and then updated to a database record.

Is it possible to have line breaks saved when a record is updated to the database? I currently view the data on the homepage, but at the moment if someone writes couple of paragraphs (including line breaks) the formatting will be lost.

If this isn’t possible no problem, but just wanted to ask if it is. Thanks.

The code on the View page looks like this:

<div class="editor-field">
        @Html.TextAreaFor(model => model.para1, new { cols = 75, @rows = 5 })
        @Html.ValidationMessageFor(model => model.para1)
</div>

I then have a button that submits the form.

The Controller code that handles the submission looks like this:

[HttpPost]
    public ActionResult Update(Data data)
    {
        if (ModelState.IsValid)
        {
            data.ID = 1; //EF need to know which row to update in the database.
            db.Entry(data).State = EntityState.Modified;
            db.SaveChanges();
            return RedirectToAction("Index", "Home");
        }
        return View(data);
    }

and the Model code for the database looks like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.Entity;
using System.ComponentModel.DataAnnotations;

namespace DFAccountancy.Models
{
    public class Data
    {
        [DataType(DataType.MultilineText)]
        public int ID { get; set; }
        public string para1 { get; set; }
        public string para2 { get; set; }
    }

    public class DataDBContext : DbContext
    {
        public DbSet<Data> Data { get; set; }
    }
}

When displaying the field as html, it will not include line breaks since they are treated as spaces in html markup. You could replace them with <br/>. It would look something like this:

<div class="display-field">
   @Html.Raw(Model.para1.Replace(Environment.NewLine, "<br/>"))
</div>

Or you could display it as preformatted text, which will preserve white space:

<div class="display-field">
    <pre>
        @Model.para1
    </pre>
</div>

Update If your model is IEnumerable<T>:

@foreach (var data in Model)
{
    <div class="display-field">
       @Html.Raw(data.para1.Replace(Environment.NewLine, "<br/>"))
    </div>
}

or

@foreach (var data in Model)
{
    <div class="display-field">
        <pre>
            @data.para1
        </pre>
    </div>
}
