You can use IsolatedStorageSetings to store application data. and read it when your app page is loaded again. here is how
public bool GetToggleValue()
{
if (IsolatedStorageSettings.ApplicationSettings.Contains("toggleValue"))
{
return bool.Parse(IsolatedStorageSettings.ApplicationSettings["toggleValue"].ToString());
}
else return false;
}
call above method in your page load to set the toggle value
and set checked unchecked value in the settings in your checked unchecked event handlers here is how
IsolatedStorageSettings.ApplicationSettings.Add("toggleValue", true);
IsolatedStorageSettings.Save();
