PropertyGroupDescriptor

The PropertyGroupDescriptor is used to group the data in a DataGrid by a property from the class that defines your objects.

Adding a PropertyGroupDescriptor

The PropertyGroupDescriptor exposes a PropertyName property that specifies the property by which the data will be grouped. It also exposes a SortOrder property, which allows for controlling the sorting order. The following examples demonstrate how to set up the DataGrid and add a PropertySortDescriptor.

Define the DataGrid in XAML

• XAML

<Grid xmlns:grid="using:Telerik.UI.Xaml.Controls.Grid" 
      xmlns:dataCore="using:Telerik.Data.Core"> 
    <grid:RadDataGrid Width="600" Height="460" x:Name="grid"> 
        <grid:RadDataGrid.GroupDescriptors> 
            <dataCore:PropertyGroupDescriptor PropertyName="Country" /> 
        </grid:RadDataGrid.GroupDescriptors> 
    </grid:RadDataGrid> 
</Grid> 

Example 2: Populating the RadDataGrid

• C#

public sealed partial class MainPage : Page 
{ 
    public MainPage() 
    { 
        this.InitializeComponent(); 
 
        List<Data> data = new List<Data> 
        { 
            new Data { Country = "Brazil", City = "Caxias do Sul"}, 
            new Data { Country = "Ghana", City = "Wa"}, 
            new Data { Country = "Brazil", City = "Fortaleza"}, 
            new Data { Country = "Italy", City = "Florence" }, 
            new Data { Country = "France", City = "Bordeaux" }, 
            new Data { Country = "Bulgaria", City = "Vratsa"}, 
            new Data { Country = "Spain", City = "Las Palmas"}, 
            new Data { Country = "France", City = "Le Mans" }, 
            new Data { Country = "Brazil", City = "Santos"}, 
            new Data { Country = "Ghana", City = "Ho"}, 
            new Data { Country = "Spain", City = "Malaga"}, 
            new Data { Country = "France", City = "Marseille" }, 
            new Data { Country = "Bulgaria", City = "Koynare" }, 
            new Data { Country = "Spain", City = "Valencia"}, 
            new Data { Country = "Ghana", City = "Kade" }, 
            new Data { Country = "Brazil", City = "Porto Alegre" }, 
            new Data { Country = "Bulgaria", City = "Byala Slatina"}, 
            new Data { Country = "Italy", City = "Naples" }, 
            new Data { Country = "Brazil", City = "Joinville" }, 
        }; 
 
        this.grid.ItemsSource = data; 
    } 
} 
 
public class Data 
{ 
    public string City { get; set; } 
    public string Country { get; set; } 
}
