CHAPTER 15 ■ ENHANCING THE WEB EXPERIENCE WITH SILVERLIGHT
medallion to install Silverlight, they will be directed to the Silverlight install page hosted
on the Microsoft web site. This will allow them to read the license agreement for using
Silverlight, and download and install the control. Once done, they can return to the original
page and view the Silverlight content.
When this property is set to true, a slightly different Silverlight medallion is presented.
This medallion contains links to the license agreement, and clicking it implies
acceptance. In this situation, the user isn’t taken away from the site; instead, the download
of the Silverlight plug-in will start automatically, and the user can install it in place.
Once done, they can access the Silverlight application straightaway.
The FullScreen Property
Silverlight can run in full screen mode, where Silverlight content is drawn on top of all
other windows. This is typically used for video playback, where the user wants to fill their
monitor with the desired video. To do this, simply set the FullScreen property of the control
to true. To change it back, set it to false.
The actualWidth Property
When the width property is set to a percentage value, the width of the Silverlight control
changes based on the user’s interaction with the browser. As a result, the value of the
actual width of the control can be read using the actualWidth property. In addition, if this
value changes, the onResize event will fire.
The actualHeight Property
When the height property is set to a percentage value, the height of the Silverlight control
may change based on the user’s interaction with the browser. As a result, the value of the
actual height of the control can be read using the actualHeight property. In addition, if
this value changes, the onResize event will fire.
The initParams Property
This is a string that you can use to set additional parameters on the control. These are
completely free format, so you can do whatever you like with them. A typical scenario for
this would be where you generate the Silverlight content from a server-side control, and
you want to maintain the state of the parameters for it on the client side.
Here’s an example of a createSilverlight function with the parameters set simply as
value1, value2, value3. In this case, you would write code to read these parameters and
respond to them as you see fit.
