The property is merely a tool for showing the correct built-in icon visual. Note: the DataGrid control does not automatically perform a sort when this property is set. When the value is null, no icon will be shown. If DataGridColumn.SortDirection property is set to Ascending, an ascending sort icon (upward facing arrow) will be shown to the right of the column header indicating that the specific column has been sorted in the ascending order.The default value for SortDirection property is null (unsorted). The DataGridSortDirection enumeration allows the values of Ascending and Descending. You can indicate the sort direction of a column by setting DataGridColumn.SortDirection? property.If both properties are set, any value of False will take precedence over a value of True. The default values for both properties is True. Alternatively, you can also set CanUserSort property on individual DataGridColumns to control which columns are sortable by the end user. CanUserSortColumns property on DataGrid can be set to True to indicate all columns in the DataGrid control are sortable by the end user. You can indicate columns are sortable in 2 ways.To implement sorting, the DataGrid control exposes the following mechanisms: Users can sort columns in the DataGrid control by tapping on the desired column headers. Mountain item = group.GroupItems as Mountain Į.RowGroupHeader.PropertyValue = item.Range ICollectionViewGroup group = e.RowGroupHeader.CollectionViewGroup Private void dg_loadingRowGroup(object sender, DataGridRowGroupHeaderEventArgs e) Handle the LoadingRowGroup event to alter the grouped header property value to be displayed Set the ItemsSource of the DataGrid control //Set the datagrid's ItemsSource to grouped collection view sourceĬustomize the Group header values through RowGroupHeaderStyles, RowGroupHeaderPropertyNameAlternative properties and by handling the LoadingRowGroup event to alter the auto-generated values in code. Create the CollectionViewSource and set to grouped collectionĬollectionViewSource groupedItems = new CollectionViewSource() Populate a CollectionViewSource instance with the grouped collection and set IsSourceGrouped property to True. ![]() GroupInfoCollection info = new GroupInfoCollection() Populate Mountains grouped collection with results of the query Implement grouping through LINQ queries ObservableCollection> mountains = new ObservableCollection>() The following walk-through shows how to implement and customize grouping in the DataGrid control.Īdd the DataGrid control to your XAML page Ĭreate the grouped collection using LINQ // Create grouping for collection You can set the DataGrid.ItemsSource to a grouped collection through CollectionViewSource with IsSourceGrouped property set to True and the DataGrid will automatically show the contents grouped under row group headers based on the data source. The DataGrid control has built-in row group header visuals for one-level grouping. See DataGrid Sample for the complete sample code and running app. The following walk-throughs demonstrate how to implement grouping, sorting and filtering for the DataGrid control through examples. The changes in the collection view are reflected in the DataGrid user interface (UI). You can then manipulate the data in the backing data source using LINQ queries without affecting the underlying data. To group, sort, and filter the data in a DataGrid, you bind it to a CollectionViewSource. ![]() It is often useful to view data in a DataGrid in different ways by grouping, sorting, and filtering the data.
