Try this
if (HasSValue() == "NoValue")
{
this.toggle.IsChecked = false;
}
else
{
this.toggle.IsChecked = true;
}
Hope this helps
Update your Constructor as follows
public Subscription()
{
InitializeComponent();
var appSettings = IsolatedStorageSettings.ApplicationSettings;
if (HasSValue() == "NoValue")
{
// Here i want to Display toggle button unchecked
}
else
{
// Here i want to Display toggle button checked
}
this.toggle.Checked += new EventHandler<RoutedEventArgs>(toggle_Checked);
this.toggle.Unchecked += new EventHandler<RoutedEventArgs>(toggle_Unchecked);
}
