c# - How do I refresh a bound GridView after the ObservableCollection<T> has be sorted? -

the implementation refresh button. use .clear() empty list, add in latest data. after data loaded use following function sort list:

public void sortbydate()     {         this.ocol = new observablecollection<ocol>(this.ocol.orderbydescending(mydate => mydate));     } 

the gridview refreshes information add it, when run sortbydate() function, gridview not refresh reflect new order. need differently?

you need raise propertychanged event property backed ocol. have changed collection , framework still databinding old collection.
