How to pass parameter into silverlight so that it is "behind the scenes"

Question

I'm brand new to learning Silverlight/XAML/C#.

I'm using an ASP.NET function to pass a string parameter to a Silverlight App. Currently I'm using the following code to simply verify that it works when the Silverlight App is loaded:

<Grid x:Name="LayoutRoot">
    <StackPanel>
        <TextBlock x:Name="txtIP" />
    </StackPanel>
</Grid>

How do I set up an element that's "behind the scenes" that doesn't necessarily display in the XAML? I thought about simply hiding the TextBlock, but I imagine there's a better way.

Answer 1

You can pass parameters to a Silverlight application using the initParams option in the plugin. Load that with some ASPNET code and you can dynamically set it at load time.

Answer 2

For further information on how to pass initParams into a Silverlight, check out Tim's video demonstration on InitParams here: Using Startup Parameters with Silverlight.

Also, check out my blog post where I cover several of the details in Tim's video and show what to do with the data once it's in the Silverlight App: Pass the IP Address of a User to Silverlight as a Parameter.
