CHAPTER 15 ■ ENHANCING THE WEB EXPERIENCE WITH SILVERLIGHT
The id Property
This is the required ID for the Silverlight control. If you want to reference the control
from JavaScript in order to manipulate it or its DOM, it needs to be identifiable, and as
such, the control needs an ID.
The width Property
This sets the width of the control in percent or pixels. This will be limited by the size of
the containing the control.
The height Property
This sets the height of the control in percent or pixels. This will be limited by the size of
the containing the control.
The background Property
This sets the background color for the control. This uses a XAML SolidColorBrush control
to determine the color, which can be a named color (e.g., Blue) or an ARGB value for 8
bits each of alpha, red, green, and blue (e.g., #00FF00BB).
The framerate Property
This sets the maximum frame rate to allow for animation. It defaults to 24 frames per second.
This is particularly useful for applications that use a lot of animation. Should you
want to smooth out the animation, you can adjust the frame rate for the optimal effect.
The isWindowless Property
By default, the Silverlight plug-in runs inline in the page, meaning that HTML content
flows around the plug-in. In many scenarios, you may want to write HTML content on
top of the Silverlight content, perhaps to have an HTML form on top of your page, or to
render a GIF or other graphics from a server that you don’t want to inject into your XAML.
This is possible using the isWindowless property. When set to true, HTML content can
be written on top of the Silverlight content. The default is false.
For example, here is the createSilverlight function amended to show isWindowless
being set:
function createSilverlight()
{
Silverlight.createObjectEx({
