Implementing jQueryMobile in .NET Framework v2.0

Create a new MVC 2.0 project

Modify the Views\Shared\Site.master file to include the following header includes:

<link
rel=”stylesheet” href=”http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.css”
/>

<script
type=”text/javascript” src=”http://code.jquery.com/jquery-1.6.1.min.js”></script>

<script
type=”text/javascript” src=”http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.js”></script>

Modify the div footer with the following markup:

<div
data-role=”footer” id=”footer” data-theme=”a”>

<h4>Page Footer</h4>

</div>

In the MVC project, select the Models folder and create a new class, Customer.

The Customer class has the following properties:

public class Customer
{
    public string Id { get; set; }
    public string FullName { get; set; }
}

Build the solution so that the Customer class will be available when we build the View later on.

In the Controllers folder, create a new Controller, CustomerController and leave the checkbox checked which reads “Add action methods for Create, Update, Delete and Details scenarios”.

In this example, I am going to delete everything but the Index and Details methods.

Now let’s create the view. Right click inside the Index method and choose Add View. Leave the view name Index and in the View data class list, choose Customer so that a strongly typed view will be created based on the Customer class we created above. Choose List from the View content list and click the Add button to generate the Index view.

The Index view will be created in a new Customer folder named Index.aspx and will have all the properties of the Customer class displayed on the page. The generated code looks like this:

<h2>Index</h2>

<table>
    <tr>
        <th></th>
        <th>
            Id
        </th>
        <th>
            FullName
        </th>
    </tr>

<% foreach (var item in Model) { %>

    <tr>
        <td>
            <%: Html.ActionLink("Details", "Details", new { id=item.Id })%> |
        </td>
        <td>
            <%: item.Id %>
        </td>
        <td>
            <%: item.FullName %>
        </td>
    </tr>

<% } %>

</table>

One property we need to change is the key which is passed to the Details page. Look for the following line in the generated code:

<%: Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ })%>

We need to change PrimaryKey to be the property of our unique value that will be passed to retrieve a Customer. In this case, the value is Customer.Id so change the line to read:

<%: Html.ActionLink("Details", "Details", new { /* id=item.Id */ })%>
where item is the single instance of a Customer in the Model.

The code behind for our controller looks like this:

public List<Customer> CustomerList;

public CustomerController()
{
    CustomerList = new List<Customer>();
    var c1 = new Customer() { Id = "1", FullName = "Peyton Manning" };
    var c2 = new Customer { Id = "2", FullName = "Drew Brees" };
    CustomerList.Add(c1);
    CustomerList.Add(c2);
}

//
// GET: /Customer/

public ActionResult Index()
{

    // In this case, View is a list of Customers
    return View(CustomerList.ToList());

}

Next we will add code to the Details method to lookup the Customer based on the link clicked on in the List on the Index view. This will pass the Customer.Id into the Details method and it’s code looks like this:

public ActionResult Details(string id)
{

    var FindCustomer = CustomerList.Find(result => result.Id == id);
    return View(FindCustomer);
}

Next we need to create the Details view by right clicking inside the Details method and choosing Add View. Leave the view name Details and in the View data class list, choose Customer so that a strongly typed view will be created based on the Customer class. Choose Details from the View content list and click the Add button to generate the Index view.

A file named Details.aspx will be created in the Customers folder. The generated html looks like this:

<h2>Details</h2>

<fieldset>
    <legend>Fields</legend>
   
    <div class="display-label">Id</div>
    <div class="display-field"><%: Model.Id %></div>
   
    <div class="display-label">FullName</div>
    <div class="display-field"><%: Model.FullName %></div>
   
   
</fieldset>

<p>
    <%: Html.ActionLink("Back to List", "Index") %>
</p>

Screen Capture
To capture whatever is on your iPad’s screen as a photo, hold the Power button, and hit the Home button. You’ll see the display flash and hear a shutter click, and the image will appear in the Camera Roll in Photos.

Lock Rotation or Mute
Lock Rotation or Mute is now controlled by the same switch and configured in Settings.
Go to Settings>General and under "Use Side Switch To:" choose either Lock Rotation or Mute.

View and Kill Running Applications
Two quick hits of the Home button can show you the apps you have running. Press and hold on one icon, and they’ll all start shaking. Tap on the small red minus sign in the top left corner of its icon to kill that app.

iPod Controls Quick Access
If you swipe left, rather than right, after you tap the Home button twice, you’ll get video/music play controls, and volume and screen-brightness sliders.

Passcode Lock
To set a 4-digit code that needs to be entered to unlock the iPad, choose General>Passcode Lock>Simple Passcode.

Find your iPad
Possibly the most valuable app you can download, Find my iPhone (it works for iPads too) once required a paid MobileMe subscription, but now all you need is an Apple ID. Download it for free in the App Store, follow the set-up instructions, and you can view your iPad on a map from your computer or cell phone.

Create a new MVC application
Add the following to the site.master to include the jQuery Mobile css and js libraries:

<head id="Head1" runat="server">
    <title><asp:ContentPlaceHolder ID="TitleContent" runat="server" /></title>
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a1/jquery.mobile-1.0a1.min.css" />
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.3.min.js"></script>
    <script type="text/javascript" src="http://code.jquery.com/mobile/1.0a1/jquery.mobile-1.0a1.min.js"></script>
</head>

Takeaways:
Look at Web Platform Installer

MVC:

There’s an MVC handler in the System.Web.Mvc.dll
There will be an IIS express.
Convention over configuration

In the Controller, created a new function Poo with ActionResult.
Run it and type /Home/Poo
No View.
Right click, in solution, in function, Add View
Now run again

Model:
Controller – retrieves Model, does stuff
View – visual represent the model

Razor:
Just out an @ sign in front of your code, and variables (making the parser starter)

Dynamic expressions in C# 4
(Dynamic view data dictionary – the operation will be resolved at runtime)
ViewBag.Whatever = PeopleList
The compiler is the first unit test, just a spell checker.

Scaffolding, Nuget,

Nuget – Add Elmah

Dependency Injection (DI)

Create class

Create interface from Class

Every time you NEW up something, think about DI.

From the Package Manager Console, PM> Install-Package Ninject.MVC3

What’s new in MVVM Light V3

Sending messages with callback

Certain classes have been added to the GalaSoft.MvvmLight.Messaging namespace, allowing sending a message and getting a callback from the recipient. These classes are:

* NotificationMessageWithCallback: Base class for messages with callback.
* NotificationMessageAction: A class with string notification, and a parameterless callback.
* NotificationMessageAction: A class with string notification, and a callback with a parameter of type T.

To send a message with callback, use the following code:
view source
print?
01.var message = new NotificationMessageAction(
02. “Hello world”,
03. callbackMessage =>
04. {
05. // This is the callback code
06. if (callbackMessage)
07. {
08. // …
09. }
10. });
11.
12.Messenger.Default.Send(message);

To register and receive a message with callback, use the following code:
view source
print?
01.Messenger.Default.Register>(
02. this,
03. message =>
04. {
05. // Do something
06.
07. // Execute the callback
08. message.Execute(true);
09. });
Messenger.Default can be overriden

The Messenger.Default property can also be replaced, for example for unit testing purposes, by using the Messenger.OverrideDefault method. All the public methods of the Messenger class have been made virtual, and can be overridden in the test messenger class.
Sending messages to interfaces

In V2, it was possible to deliver messages targeted to instances of a given class. in V3 it is still possible, but in addition you can deliver a message to instances that implement a certain interface. The message will not be delivered to other recipients.

Use the overload Messenger.Default.Send(TMessage message) where TTarget is, in fact, an interface (for example IDisposable). Of course the recipient must register to receive the type of message TMessage.
Sending messages with a token

Messages can now be sent through the Messenger with a token.

* To send a message with token, use the method overload Send(TMessage message, object token).
* To receive a message with token, use the methods Register(object recipient, object token, Action action) or Register(object recipient, object token, bool receiveDerivedMessagesToo, Action action)

The token can be a simple value (int, string, etc…) or an instance of a class. The message is not delivered to recipients who registered with a different token, or with no token at all.
