How do you sort a WPF datagrid column in code?  Meaning, if I have two columns ( FirstName and LastName ) how could I sort the LastName column in code to update datagrid?  Thanks

The DataGrid binds to a view of your data, an instance of ICollectionView. This class can be used to perform sorting:

ICollectionView view = CollectionViewSource.GetDefaultView(myDataGrid.ItemsSource);
view.SortDescriptions.Add(new SortDescription("LastName", ListSortDirection.Descending));
