GroupRowPosition Property

In This Topic

Gets or sets a value that indicates where group rows should be displayed with respect to the data.

Syntax

Visual Basic
C#

'Declaration
 
Public Property GroupRowPosition As GroupRowPosition

public GroupRowPosition GroupRowPosition {get; set;}

Remarks

Groups are created by data sources that implement the Windows.UI.Xaml.Data.ICollectionView interface.

To create groups, start by creating a data source object that implements Windows.UI.Xaml.Data.ICollectionView (such as PagedCollectionView in Silverlight or ListCollectionView in WPF), then add C1.Xaml.PropertyGroupDescription objects to the data source's ICollectionView.GroupDescriptions collection.

Once the groups have been defined, the data source will automatically create and maintain them, and the C1FlexGrid will display the results.

Example

The code below creates a data source with grouping and binds it to a C1FlexGrid.

// create PagedCollectionView used as a data source 
var data = new ObservableCollection<Customer>();
for (int i = 0; i < 10; i++)
{
  data.Add(new Customer(i));
}
var view = new PagedCollectionView(data);
using (view.DeferRefresh())
{
    view.GroupDescriptions.Clear();
    view.GroupDescriptions.Add(new PropertyGroupDescription("Country"));
    view.GroupDescriptions.Add(new PropertyGroupDescription("Active"));
}
            
// bind grid to data source 
_flex.ItemsSource = view;
            
// show group rows above the data
_flex.GroupRowPosition = GroupRowPosition.AboveData;
