ASP.NET MVC 2 Highlight Selected Menu Item on the Site Master Without Session
ASP.NET MVC2 makes so many things so easy to program but there are some basic things that are just not there and they should be.
I will be talking about a basic functionality that is a must these days.
I am talking about a menu and highlighting selected menu item.
Let’s see the problem:
I have 3 links and with each click I would like to add apropiate css class to mark my menu item as selected.
I have follwed an article on bobby’s blog.
So with this great extension it does work really well:
public static class HtmlExtensions
{
public static MvcHtmlString ActionMenuItem(this HtmlHelper htmlHelper,
String linkText, String actionName, String controllerName)
{
var tag = new TagBuilder("li");
if (htmlHelper.ViewContext.RequestContext.IsCurrentRoute(
null, controllerName, actionName) ||
htmlHelper.ViewContext.RequestContext.IsParentRoute(
controllerName, actionName))
{
tag.AddCssClass("active");
}
tag.InnerHtml = htmlHelper.ActionLink(linkText, actionName, controllerName).ToString();
return MvcHtmlString.Create(tag.ToString());
}
}
In the place of menu we stick this:
<%= Html.ActionMenuItem("Home", "Index", "Home") %>
However, there was a one little thing missing in it that I needed to have on my web.
In the About link I have a link to Biography . (Biography controller and Index action)
Since the Biography page is a part of About section I would like the “About” menu item to remain highlighted.
The solution above doesn’t work in that case.
So I decided to modify it a bit.
Let’s start from the extension:
public static class HtmlExtensions
{
public static MvcHtmlString ActionMenuItem(this HtmlHelper htmlHelper, String linkText, String actionName, String controllerName)
{
var tag = new TagBuilder("li");
if (htmlHelper.ViewContext.RequestContext.IsCurrentRoute(null, controllerName, actionName) ||
htmlHelper.ViewContext.RequestContext.IsParentRoute(controllerName, actionName))
{
tag.AddCssClass("active"); // stick class active
}
else
{
tag.AddCssClass("inactive"); // stick class inactive
}
tag.InnerHtml = htmlHelper.ActionLink(linkText, actionName, controllerName).ToString();
return MvcHtmlString.Create(tag.ToString());
}
}
We also neeed Request Extensions:
public static class RequestExtensions
{
public static bool IsCurrentRoute(this RequestContext context, String areaName)
{
return context.IsCurrentRoute(areaName, null, null);
}
public static bool IsCurrentRoute(this RequestContext context, String areaName, String controllerName)
{
return context.IsCurrentRoute(areaName, controllerName, null);
}
public static bool IsCurrentRoute(this RequestContext context, String areaName, String controllerName, params String[] actionNames)
{
var routeData = context.RouteData;
var routeArea = routeData.DataTokens["area"] as String;
var current = false;
if (((String.IsNullOrEmpty(routeArea) && String.IsNullOrEmpty(areaName)) || (routeArea == areaName)) &&
((String.IsNullOrEmpty(controllerName)) || (routeData.GetRequiredString("controller") == controllerName)) &&
((actionNames == null) || actionNames.Contains(routeData.GetRequiredString("action"))))
{
current = true;
}
return current;
}
public static bool IsParentRoute(this RequestContext context, String controller, String action)
{
var routeData = context.RouteData;
UrlModel returnUrl = null;
UrlModel requestUrl = new UrlModel { Action = routeData.GetRequiredString("action"), Controller = routeData.GetRequiredString("controller") };
UrlModel linkUrl = new UrlModel { Action = action, Controller = controller };
var urls = UrlMap.GetDictionary();
urls.TryGetValue(requestUrl, out returnUrl);
if (returnUrl != null && returnUrl.Equals(linkUrl))
return true;
else
return false; ;
}
}
And now the important part the UrlMap
public static class UrlMap
{
public static Dictionary GetDictionary()
{
Dictionary urls = new Dictionary();
urls.Add(new UrlModel { Controller = "Biography", Action = "Index" }, new UrlModel { Controller = "About", Action = "Index" });
urls.Add(new UrlModel { Controller = "Contact", Action = "GetInTouch" }, new UrlModel { Controller = "Contact", Action = "Index" });
return urls;
}
}
Here I specify that if Biography/Index is called please mark it the same as About/Index.
Don’t forget to create UrlModel class
public class UrlModel
{
public string Action { get; set; }
public string Controller { get; set; }
public override bool Equals(object obj)
{
return Equals(obj as UrlModel);
}
public bool Equals(UrlModel obj)
{
return obj != null && obj.Action == this.Action && obj.Controller == this.Controller;
}
public override int GetHashCode()
{
return (Action + Controller).GetHashCode();
}
}
Now you can stick HtmlHelper with menu in any place on the site.
<ul id="menu">
<%= Html.ActionMenuItem("Home", "Index", "Home") %>
<%= Html.ActionMenuItem("About", "Index", "About") %>
<%= Html.ActionMenuItem("Contact", "Index", "Contact") %>
</ul>
and add as amny Url Mapsas you like:
public static Dictionary GetDictionary()
{
Dictionary urls = new Dictionary();
urls.Add(new UrlModel { Controller = "Biography", Action = "Index" }, new UrlModel { Controller = "About", Action = "Index" });
urls.Add(new UrlModel { Controller = "Contact", Action = "GetInTouch" }, new UrlModel { Controller = "Contact", Action = "Index" });
return urls;
}
Here is how it looks:

CKeditor A potentially Dangerous Request.Form Value Was Detected From The Client
This solution does not require to use:
<httpRuntime requestValidationMode=”2.0″/> in web.config
or add attribute [ValidateInput(false)] to your action.
I’m using MVC2 ASP.NET 4.0 and Enitity Framework
Here we go:
1. In CKeditor config.js file
CKEDITOR.editorConfig = function (config) {
config.language = 'en',
ignoreEmptyParagraph = true;};
2. In your aspx page include:
<script type="text/javascript" src="<%= Url.Content("~/Content/scripts/wysiwyg/ckeditor.js")%>"></script>
3. Now let’s say that your View is strongly typed.
<% using (Html.BeginForm()) {%>
<%: Html.ValidationSummary(true) %>
<fieldset>
<legend>Fields</legend>
<div>
<%: Html.TextBoxFor(model => model.Title) %>
<%: Html.ValidationMessageFor(model => model.Title) %>
</div>
<div>
<%: Html.LabelFor(model => model.Descripcion) %>
</div>
<div>
<%-- Instead of
<%: Html.TextBoxFor(model => model.Description) %>
use: --%>
<textarea id="Description" name="Description" rows="2">
<%= Model.Description %>
</textarea>
<%: Html.ValidationMessageFor(model => model.Description) %>
</div>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
<% } %>
<script type="text/javascript">
CKEDITOR.replace('Description', { toolbar: '1', htmlEncodeOutput: true});
</script>
4. Your action will look this:
[HttpPost]
public ActionResult Create(MyModel model) {
if (ModelState.IsValid) {
// use System.Net.WebUtility.HtmlDecode() to store unencoded HTML
model.Description = System.Net.WebUtility.HtmlDecode(model.Description);
var entity = EntityAssemblerService.MyModelToEntity(model);
var result = _repository.Add(entity);
_repository.Save();
return View(model);
}
else {
return View(model);
}
}
Good Luck
Local and Remote PHP Debuging in NetBeans with Xdebug on Google Chrome (just like in Visual Studio)
Have you ever wonder how to debug your php projects just like it is done in Visual Studio?Well it is not that simple as in Visual Studio.NET where you just click “Debug” and all is set for you. You need to install and configure couple of things but that’s about it.
In this tutorial we are going to set xdebug for php on Ubuntu server and we are going to use Google Chrome as a browser in our debugging process.
Let’s setup server. Log in to your ubuntu box.
1. Install xdebug for php
sudo aptitude install php5-xdebug sudo /etc/init.d/apache2 restart
2. Check installation
php -v arturito@hokage:~$ php -v PHP 5.3.3-1ubuntu9.3 with Suhosin-Patch (cli) (built: Jan 12 2011 16:08:14)Copyright (c) 1997-2009 The PHP GroupZend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies with Xdebug v2.1.0, Copyright (c) 2002-2010, by Derick Rethans
3. Edit php.ini
sudo nano /etc/php5/apache2/php.ini
4. Stick these lines in:
zend_extension="/usr/lib/php5/20090626+lfs/xdebug.so" xdebug.remote_enable=on xdebug.remote_host=localhost
5. Install Google Chrome xdebug extension:
https://chrome.google.com/webstore/detail/eadndfjplgieldjbigjakmdgkmoaaaoc
6. In Chrome go to Tools>Extensions
7. Click on Options and add domains you want to be able to debug
8. Open NetBeans and go to Tools > Options > PHP
9. Now create new project as a test and set the breakpoint.
10. Hit Ctrl + F5
Your browser will hang.
and you will be able to step through the code
Additional:
If your webserver is not installed on your machine but it is on the separate one you should set xdebug.remote_host to the IP of your development machine.
For example I run ubuntu with apache in virtual box so I set
xdebug.remote_host=192.168.1.5
where 192.168.1.5 is the IP of my Windows host OS where I have NetBeans installed.
Apple TV 2G Untethered Jailbreak And XBMC Installation iOS 4.3 working
This tutorial is out of date. It worked for people who had Apple TV 2 with 4.1.1 and accidentally updated to 4.2.1.
Please follow these instructions instead:
http://arturito.net/2011/04/09/apple-tv-2g-untethered-jailbreak-and-xbmc-installation-ios-4-3-with-sn0wbreeze/
—————————————————————————————————————————————————————————
My friend accidently updated his Apple TV 2G to version 4.2.1 (2100) iOS 4.3 which removed jailbreak and XBMC I put for him before with version 4.1.1.
I wrote this tuorial: http://arturito.net/2011/04/09/apple-tv-2g-untethered-jailbreak-and-xbmc-installation-ios-4-3-with-sn0wbreeze/
which deals with iOS 4.3 and installs XBMC. All installs well but…. we all got audio device error and could not play MKV files.
I turned to Seas0nPass and PwngeTool but it had the same problem.
But thanks to users comments especially Fluxx and Czechmarty I managed to fix it.
I still don’t know how I managed to restore to previous version without SHSH blobs ………but I did. I assume that if Apple TV firmware version shows 4.2.1 (2100) the iOS must be 4.3.
I asked question on XBMC forums in order to confirm that.
http://arturito.net/2011/04/12/apple-tv-2g-untethered-jailbreak-and-xbmc-installation-ios-4-3-working/
All replies I got confirmed that 4.2.1 (2100) for ATV2 is iOS 4.3.1
Well let’s start:
Download:
1. iTunes 10.2.1 – might work with newer version but this is waht I tried and worked for me.
http://www.oldapps.com/itunes.php?old_itunes=71
2. Apple TV Fimrware 41.1 (iOS 4.2.1)
http://appldnld.apple.com/AppleTV/061-9978.20101214.gmabr/AppleTV2,1_4.2.1_8C154_Restore.ipsw
3. Uninstall your current version of iTunes and install version 10.2.1
4. Fire iTunes, connect Apple TV with USB cable only. Let Windows install all drivers.
5. Once you see Apple TV in iTunes hold Shift and click Restore.
6. Select AppleTV2,1_4.2.1_8C154_Restore.ipsw and wait until it completes
7. Go to this post

Apple TV 2G Untethered Jailbreak And XBMC Installation iOS 4.3 With Sn0wBreeze
UPDATE: 10.01.2012
As you can see this post is quite old now so this method might not work for you as Apple keeps updating their Apple TV 2G.
Please find out first which version of Apple TV 2G you have. To get this info check this one:
http://arturito.net/2011/11/30/how-to-find-firmware-version-of-apple-tv-2g-software-and-system-version/
If your System Version is greater than 4.3 instructions in this tutorial won’t work for you. Shortly I will be posting an update.
If your System Version is 4.3 you can go ahead:
In one of my previous post I explained how to jailbreak Apple TV 2G and install XBMC on it.
This has been some time ago and it worked for Apple TV2G version 4.1.1 and below. I used GreenP0ison RC6.
Since then Apple has release version 4.2.1 (iOS 4.3) and GreenP0ison can’t do the jailbreak of this version. I’ve heard that Sn0w Breeze can jailbreak the latest (4.3) Apple TV 2G software version and I have decided to try it:
What we need is:
1. iTunes installed
2. iREB-r4
3. sn0wbreeze-v2.5.1
4. AppleTV2,1_4.3_8F202_Restore.ipsw
You can google these or simply download zip file with all files apart from iTunes:
http://www.megaupload.com/?d=96Y7FUVR
1. Unpack it all and run iREB-r4. Connect only USB cable.
2. Click on Apple TV2
3. Once in DFU mode you will get this:
4. Ok so before we go to iTunes and do Restore let’s prepare firmware. Let’s launch Sn0wBreeze :
5. Clicking in the link to download IPSWs didn’t work for me so that’s why we got firmware downloaded before. Click on Browse and point to the firmware file: AppleTV2,1_4.3_8F202_Restore.ipsw
6. Hit Continue and be patient. It might take sometime
7. In your desktop there should be file called: sn0wbreeze_Apple TV 2-4.3.ipsw. Hit OK.
8. You should get this message:
9. Now got your iTunes and in the right sidebar select Apple TV
10. Hold SHIFT button and press Restore
11. Select sn0wbreeze_Apple TV 2-4.3.ipsw located on your Desktop and wait until the process is complete.
12. Now when you connect Apple TV2G to your TV you should get NitoTV . To install XBMC go to
and jump to step 4.
Before leaving any questions in comments please post your System and Software Version. You can get that information by following this guide:
Good Luck! 
How to fix XBMC that quits on Apple TV 2G and disable updates
If you have NitoTV installed there is a very simple solution:
1. NitoTV>Settings>Update NitoTV
2. NitoTV>Settings>Reboot
3. NitoTV>Install Software> updatesBeGone
4. NitoTV>Settings>Reboot
Silly message will go away
How to change time zone on Apple TV 2G
On the jailbreaked Apple TV 2 login as root using ssh.
find / -name localtime
it should come up with
/private/var/db/timezone/localtime
now got to this directory
cd /private/var/db/timezone/
remove link
rm localtime
and create new one for example in my case Madrid.
ln -s /usr/share/zoneinfo/Europe/Madrid localtime
to get your time zone
check what’s available in
cd /usr/share/zoneinfo/
Reboot and that should be it.
Apple TV 2 XBMC installation dkg was interrupted, you must manually run dpkg –configure –a to correct the problem
In the artice below I described how to install XBMC on Apple TV 2.
Some users reported errors while installing XBMC on Apple TV 2.
In the step 5 where we go to NitoTV > Install Software > XBMC-ATV2
Apple TV 2 downloads XBMC, reboots and XBMC does not appear in the menu or this error appears:
E: dkg was interrupted, you must manually run ‘dpkg –configure –a’
To correct the problem follow these steps:
1. Find out the IP address of the APTV2 in Settings >Network
2. If you are on Windows download Putty http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe (it is ssh client)
3. Launch Putty and in Host Name (or Ip Address) enter the IP address of Apple TV 2 for example 192.168.1.24
4. If you get message about encryption click Yes
5. You will get login screen. As user type in root and as password alpine
6. Launch the following command:
apt-get install wget wget -O- http://apt.awkwardtv.org/awkwardtv.pub | apt-key add - echo "deb http://apt.awkwardtv.org/ stable main" > /etc/apt/sources.list.d/awkwardtv.list echo "deb http://mirrors.xbmc.org/apt/atv2 ./" > /etc/apt/sources.list.d/xbmc.list apt-get update apt-get install org.xbmc.xbmc-atv2
If by any chance you get error exit status 1
1. Run commands:
apt-get remove org.xbmc.xbmc-atv2 apt-get install org.xbmc.xbmc-atv2 --fix-missing
2. XBMC should appear in Apple TV 2 Menu.
If you still get the problem the best idea is to do Restore thorugh iTunes and start the process again.
For some reason restore and installation worked for many.
Good Luck
