I have a datagrid with rowdetails, but the data in the rowdetails is calculated.

When I select an item, I calculate the data that needs to be shown and update the Binding List of the DataGrid.

The rowdetails are not shown immediately. But when you scroll a little, they magically appear.

I fear this is a bug in the refresh of the RowDetails.

The issue is the BookListItem class does not raise PropertyChanged for when the BookDetails changes. As a result, the TextBlock in the RowDetails is empty so it has 0 Height, and it appears that the RowDetails is not working. If the BookListItem implements INotifyPropertyChanged and raises PropertyChanged for BookDetails, you will see the issue go away:

    public class BookListItem : INotifyPropertyChanged
        public event PropertyChangedEventHandler PropertyChanged;
        private string _bookdetails;

        public BookListItem(Book book)
            Book = book;

        public Book Book { get; set; }
        public string BookDetails
                return _bookdetails;
                if (_bookdetails != value)
                    _bookdetails = value;

        private void RaisePropertyChanged(string propertyName)
            if (this.PropertyChanged != null)
                this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
