The objects in the collection must implement the INotifyPropert圜hanged changed interface and the IEditableObject interface in order for the DataGrid to respond correctly to property changes and edits. This enables you to data bind to the collection in XAML. If you use List to create your collection, you should create a new class that inherits from List instead of instantiating an instance of List. To bind a DataGrid to a CollectionViewSourceĬreate a data collection that implements the IEnumerable interface. In this example, the DataGrid is bound to a CollectionViewSource that provides these functions for a List of Task objects. To group, sort, and filter data in a DataGrid control, you bind the DataGrid to a CollectionView that supports these functions.

Grouped data in a DataGrid Using a CollectionViewSource as an ItemsSource Grouping, sorting, and filtering are performed on the CollectionViewSource and are displayed in the DataGrid UI. The CollectionViewSource is used as the ItemsSource for the DataGrid. In this example, a collection of Task objects is bound to a CollectionViewSource. The CollectionViewSource class enables you to set the properties of a CollectionView from XAML. The CollectionView class provides grouping and sorting functionality for a data source that implements the IEnumerable interface. The changes in the collection view are reflected in the DataGrid user interface (UI). You can then work with the data in the CollectionView without affecting the underlying source data. To group, sort, and filter the data in a DataGrid, you bind it to a CollectionView that supports these functions. It is often useful to view data in a DataGrid in different ways by grouping, sorting, and filtering the data.
