Just make an event like
((BooksViewModel)LayoutRoot.DataContext).PropertyChanged += new PropertyChangedEventHandler(BooksView_PropertyChanged);
and call the
void BooksView_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
if (e.PropertyName == "AnyDistinguishedstring")
{
Pager.PageIndex = 4; //it will take you to the page 5
}
}
and From Viewmodel call the
NotifyPropertyChanged("AnyDistinguishedstring");
will do the trick. :)
