Overview
 Project Demo
 Reviewing Concepts and Architecture
 Code Walk-Through
 Information About Joining the Fun!

The Silverlight UG Website
Starter Kit
 SUGWSK – Worst Acronym Ever?

 The functionality for creating a rich Silverlight User Group
Website….or User Group Website….. Or Data Driven
Application

 The project implements Silverlight 4, will explore its new
features, and apply them to the User Group functionality

 Tools used: Silverlight 4 Tools, Blend 4, Simple MVVM
Framework

Architecture
 Silverlight 4
 RIA Services
 Entity Framework
 MVVM using SimpleMVVM
 SQL Server Express
 Membership using Standard .NET Membership
provider

Demo: Authentication & Social
Networking Broadcasting

Membership and Authentication
Back to the good ole days of .NET with membership and roles 

if (!AppServices.WebContext.Current.User.IsAuthenticated)
{
var loginWindow = new LoginRegistrationWindow();
loginWindow.Show();

loginWindow.Closed += new EventHandler(loginWindow_Closed);
}
else
{
PrintBadgePage PrintBadgeChildWindow = new PrintBadgePage();
PrintBadgeChildWindow.Show();
}

Membership and Authentication
Back to the good ole days of .NET with
membership and roles 
<profile>
<properties>
<add name="FriendlyName" />
<add name="TwitterID" />
<add name="LinkedInID" />
<add name="Website" />
<add name="Address" />
<add name="City" />
<add name="State" />
<add name="ZipCode" />
<add name="Bio" />
<add name="PhotoURL" />
<add name="FacebookID" />
<add name="LinkedInID" />
</properties>
</profile>

Demo: Model – View – ViewModel
& RIA Services

Model – View – ViewModel
 The Model class has the code to contain and access
data.

 The View is usually a control that has code (preferably
in the form of XAML markup) that visualizes some of
the data in your model and ViewModel.

 And then there is a class named either
ViewModel, PresentationModel, or Presenter that will
hold as much of the UI logic as possible.

WCF RIA Services
 Simplifies the traditional n-tier application pattern by
bringing together the ASP.NET and Silverlight platforms.
 Provides a pattern to write application logic that runs on
the mid-tier and controls access to data for
queries, changes and custom operations.
 It also provides end-to-end support for common tasks such
as data validation, authentication and roles by integrating
with Silverlight components on the client and ASP.NET on
the mid-tier.

RIA Services on MVVM
WFC RIA Services
- Two key aspects:
- RIA Services
Class Library
- Separation Into
Partial Classes

Printing (Yes, Actual Printing)
 The Silverlight 4 printing support allows you to specify a XAML tree to
print.

 Overall its pretty simple. It all starts with the PrintDocument class. This
class exposes several events that are used to call back to ask you about
how to print individual pages.

 The PrintPage event passes in a PrintPageEventArgs object
that contains a couple of pieces of information.
 Width and Height - used to help size your XAML before being
printed.
 PageVisual which is any UIElement-derived element to be
printed. Typically this is either a single control (e.g. DataGrid)
or a container for other elements. You can also specify the
whole page if you're just doing page printing.
 HasMorePages - specify whether there are more pages to
print with the HasMorePages property.

Printing (Yes, Actual Printing)
 Simple PrintDocument creation:
PrintDocument doc = new PrintDocument();
doc.DocumentName = "Sample Print";
doc.StartPrint += new EventHandler<StartPrintEventArgs>(doc_StartPrint);
doc.PrintPage += new EventHandler<PrintPageEventArgs>(doc_PrintPage);
doc.Print();

 Printing an Element
void doc_PrintPage(object sender, PrintPageEventArgs e)
{
// Stretch to the size of the printed page
printSurface.Width = e.PrintableArea.Width;
printSurface.Height = e.PrintableArea.Height;
// Assign the XAML element to be printed
e.PageVisual = printSurface;
// Specify whether to call again for another page
e.HasMorePages = false;
}

Printing ( 1 of 2)
Printing an Event Pass
void btnPrint_Click(object sender, RoutedEventArgs e)
{
//Create Event Badge Print Document
PrintDocument badge2Print = new PrintDocument();
badge2Print.DocumentName = "EventAttendeeBadge";

//Hide the print section at the end of printing
badge2Print.EndPrint += (owner, args) =>
{
printGridCanvas.Visibility = Visibility.Collapsed;
};

//Set the PageVisual element to the PrintGrid
badge2Print.PrintPage += (owner, args) => { args.PageVisual = printGrid; };
badge2Print.Print();
}

Printing (2 of 2)
Preparing a Grid for printing..

void preparePrintData()
{
textBlockAttendeeIdPrint.Text = textBlockAttendeeId.Text;
textBlockAttendeeNamePrint.Text = textBlockAttendeeNamePrint.Text;
textBlockMeetingTimePrint.Text = textBlockMeetingTime.Text;
textBlockMeetingTitlePrint.Text = textBlockMeetingTitle.Text;

imageRectanglePrint.Fill = WebcamRectangle.Fill;

printGridCanvas.Visibility = Visibility.Visible;
}

Demo: Video & WebCam Support

Team Member Victor Gaudioso getting our live
streaming working for the first time!

Video and WebCam Support ( 1 of 2)
void StartCamBtn_Click(object sender, RoutedEventArgs e)
{
if (!VideoIsPlaying)
{
VideoIsPlaying = true;
if (CaptureDeviceConfiguration.AllowedDeviceAccess ||
CaptureDeviceConfiguration.RequestDeviceAccess())
{
MyVideoBrush.SetSource(CapSrc);
WebcamRectangle.Fill = MyVideoBrush;
CapSrc.Start();
StartCamBtn.Content = "Stop Web Cam";
}
}
else
{
VideoIsPlaying = false;
CapSrc.Stop();
StartCamBtn.Content = "Start Web Cam";
}

}

Video and WebCam Support (2 of 2)

void UploadPictureBtn_Click(object sender, RoutedEventArgs e)
{
OpenFileDialog pfd = new OpenFileDialog();
pfd.Filter = "PNG Files (*.png)|*.png|All Files (*.*)|*.*";
pfd.FilterIndex = 1;

if ((bool)pfd.ShowDialog())
{
Stream stream = pfd.File.OpenRead();
BitmapImage bi = new BitmapImage();
bi.SetSource(stream);
ImageBrush brush = new ImageBrush();
brush.ImageSource = bi;
WebcamRectangle.Fill = brush;
}
}
