Two ways of putting silverlight in a page

Hello,

I saw two ways of putting silverlight in a page.

One way is to use a object tag like this:

  <object data="data:application/x-silverlight," type="application/x-silverlight-2-b1" width="100%" height="100%">
   <param name="source" value="ClientBin/Test.xap"/>
   <param name="onerror" value="onSilverlightError" />
   <param name="background" value="white" />
    <a href="http://go.microsoft.com/fwlink/?LinkID=108182" style="text-decoration: none;">
        <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight" style="border-style: none"/>
   </a>
  </object>

 The other is to use script manager and silverlight control:

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
        <div  style="height:100%;">
            <asp:Silverlight ID="Xaml1" runat="server"
                Source="~/ClientBin/LessonPlayer.xap" Version="2.0" Width="320px"
                Height="278px" />

 What is the difference between the two ways?

Thanks.

There is also a third option - use createSilverlight() from Silverlight.js

I haven't used ASP a lot so I cannot comment on that alot, but I think there probably isn't a big difference, if at all.

But consirning JavaScript vs. object tag I can say the following.

1. Using createSilverlight() function results with same outcome as the object tag but:
• you have to include the Silverlight.js file, its not big but it still has an effect on your bandwith.
• the default behaviour of IE is that if you add a Silverlight application with object tag, IE blocks it as a possibly malicious ActiveX component. You don't have this problem when using JavaScript.

Also have a look at these documents from msdn:

• Instantiating a Silverlight Plugin
• Using Silverlight.js

Hope this helps.
