Question

I’m using DataGrid bound to List property in my user control:

<DataGrid x:Name="dataGrid" .... 
      ItemsSource="{Binding ItemSorce, ElementName=UserControl}" 
                            ....>                           

My problem is that I need it updated every time I change the source.

I had the user control implement INotifyPropertyChanged and do raise PropertyChanged event, but the DataGrid original content remains the same.

I’ve read that for the DataGrid to change, I should set BindingSource between ItemSorce and the binding, but all examples I’ve seen are doing this via c# source code.

How do I set BindingSource via xaml, and is this the best way to synchronize the DataGrid and ItemSorce?

Answer 1

Use a ObservableCollection<> instead of a List<> as it is designed for bindings.
