Using URL Parameters

URL Parameter is great way to pass the information to html page. Managed OM around HTML DOM makes it really easy for Silverlight application to use those parameters at the start up time.

Page.Xaml

<Canvas
        xmlns="http://schemas.microsoft.com/client/2007" 
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        x:Name="parentCanvas" 
        Loaded="Page_Loaded" 
        x:Class="UrlParam.Page;assembly=ClientBin/UrlParam.dll"
        Width="640"
        Height="480"
        Background="White"
        >
    <TextBlock x:Name="txtParam" Width="324" Height="27" 
             Canvas.Left="79" Canvas.Top="67" Text="Param:" 
             TextWrapping="Wrap"/>
</Canvas>

Page.xaml.cs

using System;
using System.Windows.Browser;
using System.Windows.Controls;
using System.Collections.Generic;

namespace UrlParam
{
    public partial class Page : Canvas
    {
        public void Page_Loaded(object o, EventArgs e)
        {
            // Required to initialize variables
            InitializeComponent();
            Dictionary<string, string> urlparams = HtmlPage.QueryString as Dictionary<string,string>;
            string s = string.Empty;
            urlparams.TryGetValue("Param1", out s);
            txtParam.Text = "Param1: " + s;
        }
    }
}

Debugging this gets trickier though, I had to launch  browser, then attach debugger to it and then run the browser with URL that has parameters.
