[DotNetDevelopment] Silverlight detection!!

[sa]

Hi,

I am using ASP.NET 3.5 with C#. I need to write a code that will help
me detect if Microsoft's Silverlight is installed on the clients
browser or not. Is it is not installed I display a NoSilverLight.aspx
page. If it is installed I dispaly a mySilverlight.aspx page.

I have done it in 2 ways and none of them are working
--------------------------------------------------------------------

Method 1:

<div id="silverlightControlHost">
        <script type="text/javascript">
          if (Silverlight.available) //true silverlight installed
          {
             document.write("Silverlight is available!");

          }
          else {
            document.write("Silverlight is NOT available!");

          }
        </script>
    </div>
-------------------------------------------------------------------------------------------------------------------------
Method 2:
<script src="Intel.ARK.Silverlight1_0.Controls.Client.Silverlight.js"
type="text/javascript"></script>

var  = Silverlight.isInstalled(null)
        if ( Silverlight.isInstalled(null) )
        {
            document.write("Silverlight is available!");        }
