CHAPTER 15 ■ ENHANCING THE WEB EXPERIENCE WITH SILVERLIGHT
Background="White"
x:Name="Page">
As you can see, this is straightforward XML, with the standard parent/child format.
The element is a child of the element, and thus it is contained by it.
This XAML would typically be saved as a file called Page.xaml or something similar.
The rest of this example assumes that it is called Page.xaml.
Creating an Instance of the Silverlight Plug-In
The Silverlight.js library contains the createObject and createObjectEx functions, which
are used to generate the correct or tag to create the Silverlight component
for the current browser. These functions perform identical tasks, the difference
between them being that createObjectEx uses the JSON notation for bundling parameters
as a matter of convenience.
It is good programming practice to separate this call from the page hosting it so that
the details of the parameters used for the Silverlight component are externalized. So, for
example, the HTML markup for the page would look something like this:
createSilverlight();
The createSilverlight function would be hosted in an external JavaScript file that is
referenced by the HTML. This function would then call createObject or createObjectEx
like this:
function createSilverlight()
{
Silverlight.createObjectEx({
source: "Page.xaml",
parentElement: document.getElementById("SilverlightControlHost"),
id: "SilverlightControl",
properties: {
width: "100%",
height: "100%",
