How to inject Javascript in the WP7 WebBrowser control?
I have a WebBrowser control in my MainPage.xaml serving an external web page.
<phone:WebBrowser
Name="TravelPlanner"
Source="http://URL-HERE.com"
IsScriptEnabled="True"/>
Is it possible for me to somehow inject or serve my own CSS (or JavaScript for that matter)?
Yes. By invoking WebBrowser.InvokeScript after WebBrowser.LoadCompleted you can execute arbitrary javascript code in a webbrowser control. Web apps can then use WebBrowser.ScriptNotify to talk back to C#.
