Passing Querystring Parameters to a Silverlight Control

The approach to passing Querystring parameters to a Silverlight 2.0 Control that works for me is pretty simple. We check for the presence of Querystrings in the app.xaml Application_Startup using the Silverlight HTML Bridge and pass those values to the page’s constructor.

APP.XAML ——————————–

private void Application_Startup(object sender, StartupEventArgs e)
{
int fid = HtmlPage.Document.QueryString["fid"] != null ?
int.Parse(HtmlPage.Document.QueryString["fid"].ToString()) : -1;
int pid = HtmlPage.Document.QueryString["pid"] != null ?
int.Parse(HtmlPage.Document.QueryString["pid"].ToString()) : -1;

this.RootVisual = new InField.Grid(fid, pid);

}

GRID.XAML STARTUP PAGE ———————–

private int employeeID = 1;
private int postID = 1;

public Grid(int _employeeID, int _postID)
{

employeeID = _employeeID;
postID = _postID;

InitializeComponent();
PopulateGrid();
editing = false;
}
