Question

Let me explain my problem. I am working with Caliburn Micro and have a datagrid where a ObservableCollection is being binded as an Itemsource:

private static ObservableCollection<Models.GamesProperties> _dgGames;

public ObservableCollection<Models.GamesProperties> DgGames
{
    get { return _dgGames; }
    set
    {
        _dgGames = value;
        NotifyOfPropertyChange(() => DgGames);
    }
}

So, when I load my data from my database, the collection will be filled and binded to my datagrid (called DgGames)

Everything is fine so far. I have defined for each DataRow “DataRowDetails”. Contains an ImageSource, some TextBlocks and so on. The mentioned collection above contains also those DataRowDetails.

I have now created another View and ViewModel for a dialog window in order to change the DataRowDetails. It does work, but the datagrid (DgGames) won’t apply these changes. It does not show any update i have done to the collection. What am I missing ?

Thanks in advance to those who can help me.

In order to see modification on the fly in the grid too, Models.GamesProperties has to implemen properly INotifyPropertyChanged. Since you are using Caliburn, you probably want to derive it from PropertyChangedBase.
