Hey everyone,
Just a quick post on how to stop text taking up more than one line using only CSS:
.truncate {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}
You can check it out using this fiddle: http://jsfiddle.net/wb5m7/

Hey everyone,
Just a quick post on how to force a page refresh with JavaScript (no jQuery required):
location.reload();
Note that the reload function accepts a boolean parameter that can be used for force a server refresh. Alternatively, it just defaults to the cache.

Hey everyone,
Just a quick post on how to detect a file’s size with jQuery. I’m currently using a version of this for basic client side validation:
Upload image:
$(document).ready(function(){
$('#image-file').bind('change', function() {
var fileSize = this.files && this.files.length > 0 && this.files[0].size ? this.files[0].size / 1024 / 1024 : 0;
if(fileSize > 0){
$('body').append('' + fileSize + ' MB');
}
else{
$('body').append('' + fileSize + ' MB');
}
});
});
.file{
padding: 5px 7px;
border-radius: 3px;
background-color: green;
color: white;
margin: 5px;
}
.file.valid{
background-color: rgb(127, 197, 127);
}
.file.invalid{
background-color: rgb(197, 127, 127);
}

Hey everyone,
For some reason the “My Selling Tools” option is now missing on my production account. Unfortunately the only way to get around this that I’ve come across is to access the required features directly. For example:
API Access:

If you’ve got any other links that might be useful please let me know and I’ll add them.
Hey everyone,
This is just a short post showing how to render views as strings. I’ve used this as a quick way to generate email templates. The logic to render a view as a string is as follows:
public static string RenderRazorViewToString(Controller controller, string viewName, string content)
{
controller.ViewBag.Content = content;
using (var sw = new StringWriter())
{
var viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext, viewName);
var viewContext = new ViewContext(controller.ControllerContext, viewResult.View, controller.ViewData, controller.TempData, sw);
viewResult.View.Render(viewContext, sw);
viewResult.ViewEngine.ReleaseView(controller.ControllerContext, viewResult.View);
return sw.GetStringBuilder().ToString();
}
}
The Email Template: Views/Emails/DefaultTemplate
@{
Layout = null;
}

In your controller:
public String TestEmail(String content)
{
Email email = new Email() {
To = "lls@live.com.au",
From = Email.Fields.From.NoReply,
Body = content,
Subject = "Test",
TemplateName = @"~ViewsEmailsDefaultTemplate.cshtml",
UseTemplate = true
};
email.SendEmail(this);
db.Emails.Add(email);
db.SaveChanges();
return email.Body.ToString();
}
If you looking to implement this with your emails, note that it builds on top of the email class we created back in this post: http://www.whatibroke.com/?p=963
If you’re just going to be using it directly within the controller, using the original code from over StackOverflow will probably be your best bet: http://stackoverflow.com/a/2759898/522859
Hey everyone,
Just a quick one, how to redirect to root from a controller:
return Redirect(Url.Content("~/"));

Hey everyone,
Coming from Rails I’d grown quite fond of flash messages. Unfortunately there isn’t a built in way of doing this in MVC4. Luckily, there’s a five minute solution posted on StackOverflow: http://stackoverflow.com/a/11809178/522859
Once implemented, it works just like in Rails:
this.Flash("We need you to login before you can edit anything.", FlashEnum.Warning);
Definitely worth checking out if you’ve got time, even more so if you’ve come over from Rails!
Hey everyone,
Just a quick post on something useful I came across today. In JavaScript you can access the stack trace via console using the following command (ctrl + shift + j):
console.trace()
In Chrome, this will let you navigate to each relevant call by clicking the line number in the console window. I’ve found it pretty useful for backtracking through jQuery exceptions.

Hey everyone,
Ran into a bit of an issue today where a url was being shortened in Chrome’s console. It turns out that there’s a quick command you can use to copy the full value:
copy(myVariable)
Type copy into the console window and pass the variable you want to copy as a parameter. This will then be saved to your clipboard for pasting.

Hey everyone,
Just a really basic model that can be used to send emails on GoDaddy in MVC4.
The model:
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations.Schema;
using System.Linq;
using System.Web;
using System.Net.Mail;
using System.ComponentModel.DataAnnotations;
namespace LL.Models
{
public class Email
{
[Key]
public int EmailId { get; set; }
public string From { get; set; }
public string To { get; set; }
public string Subject { get; set; }
public string Body { get; set; }
public DateTime Sent { get; set; }
public string Status { get; set; }
public string Log { get; set; }
public void SendEmail()
{
MailMessage mail = new MailMessage();
mail.To.Add(this.To);
mail.From = new MailAddress(this.From);
mail.Subject = this.Subject;
mail.Body = Body;
mail.IsBodyHtml = true;
mail.Priority = MailPriority.Normal;
SmtpClient smtp = new SmtpClient();
smtp.Host = "relay-hosting.secureserver.net";
smtp.UseDefaultCredentials = true;
smtp.Port = 25;
smtp.EnableSsl = false;
try
{
smtp.Send(mail);
this.Status = Fields.Status.Success;
}
catch(Exception e)
{
this.Log = e.Message;
}
this.Sent = DateTime.Now;
}
[NotMapped]
public class Fields
{
public class From
{
public const String NoReply = "noreply@yoursite.com.au";
public const String Support = "support@yoursite.com.au";
}
public class Status
{
public const String Success = "Success";
public const String Error = "Error";
}
}
}
}
Using it in a controller:
using LearnerLessons.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace LL.Controllers
{
public class TestController : Controller
{
private LLDBContext db = new LLDBContext();
public String TestEmail(String content)
{
Email email = new Email() { To = "lls@live.com.au", From = Email.Fields.From.NoReply, Body = content, Subject = "Test" };
email.SendEmail();
db.Emails.Add(email);
db.SaveChanges();
return email.ToString();
}
}
}
