You can call this method to programmatically collapse row groups in a DataGrid control that contains grouped data. You can use the GetGroupFromItem method to get the particular group that a specified item belongs to. Alternatively, you can iterate through the Groups collection to expand all row groups.
The following example demonstrates how to collapse all row groups in a DataGrid control. This example is part of a larger example available in the How to: Group, Sort, and Filter Data in the DataGrid Control topic.
private void CollapseButton_Click(object sender, RoutedEventArgs e) { PagedCollectionView pcv = dataGrid1.ItemsSource as PagedCollectionView; try { foreach (CollectionViewGroup group in pcv.Groups) { dataGrid1.ScrollIntoView(group, null); dataGrid1.CollapseRowGroup(group, true); } } catch (Exception ex) { // Could not collapse group. MessageBox.Show(ex.Message); } }
