![]() ![]() In XAML, set the PropertyName to the name of the property to group by. You can specify the property in XAML or in code. To group items in a DataGrid using XAMLĬreate a PropertyGroupDescription that specifies the property to group by. To specify how items are grouped in a DataGrid, you use the PropertyGroupDescription type to group the items in the source view. ICollectionView cvTasks = CollectionViewSource.GetDefaultView(dataGrid1.ItemsSource) ĭim cvTasks As ICollectionView = CollectionViewSource.GetDefaultView(dataGrid1.ItemsSource) To access the CollectionViewSource from your code, use the GetDefaultView method to get a reference to the CollectionViewSource. Ĭreate an instance of the DataGrid class, and set the ItemsSource property to the CollectionViewSource. In XAML, create an instance of the CollectionViewSource class, set the x:Key Directive, and set the instance of your collection class as the Source. In XAML, create an instance of the collection class and set the x:Key Directive. ' Creating the Tasks collection in this way enables data binding from XAML. Creating the Tasks collection in this way enables data binding from XAML. Public class Tasks : ObservableCollection For more information, see Implement Property Change Notification. 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. ![]()
