Tip: How to pass initialize parameters to Silverlight application using <object> element?
If you want to pass initialize parameters to Silverlight application from an HTML/ASPX page, you have to find the place where your Silverlight control is inserted into the page using the <object> element and insert the bold line bellow.
HTML
<object data="data:application/x-silverlight," type="application/x-silverlight-2-b2" width="100%" height="100%">
...
<param name="initParams" value="param1=value1,param2=value2" />
...
</object>
As you can see you have to insert one new element <param name="initParams" value="parameters"/> as a child of the <object> element. The syntax for parameters definition is pretty straightforward - you just have to enumerate all parameters and their values separated by commas like this: "parameter1=value1,parameter2=value2,parameter3=value3". Once the initialize parameters have been defined, you can obtain them in your application startup event handler using the InitParams property of the StartupEventArgs like this:
C#
private void Application_Startup( object sender, StartupEventArgs e )
{
//... Other code here ...
string param1Value = e.InitParams[ "param1" ];
