How to remove DataGrid’s blank row when binding to a ObservableCollection?
The same problem persist in WPF 4.0 version of DataGrid, and it is caused by the add-new row which it shows automatically for ObservableCollection ItemsSource. Setting IsReadOnly as True it’s too radical IMHO. I solved it by disabling CanUserAddRows property if you don’t need that behavior, but you still want cells to be modified: CanUserAddRows=”False”
