PropertySortDescriptor

You can sort the data in a DataGrid by a property value from the class that defines your objects. This can be achieved with a PropertySortDescriptor and setting its PropertyName property.

• PropertyName (string): Gets or sets the name of the property that is used to retrieve the key to sort by.

You can easily choose the sorting order - Ascending or Descending - using the SortOrder property.

To apply multiple sorting, you need to enable it through the RadDataGrid.UserSortMode = "Multiple" and add two or more sort descriptors.

The following example will show how to sort data by property:

First, define a DataGrid instance in XAML with a PropertySortDescriptor which points to a property from the model through its PropertName property:

<grid:RadDataGrid Width="600" Height="460" x:Name="grid">
    <grid:RadDataGrid.SortDescriptors>
        <dataCore:PropertySortDescriptor PropertyName="Country"/>
    </grid:RadDataGrid.SortDescriptors>
</grid:RadDataGrid>

Be aware that you need to define the correct namespace for PropertySortDescriptor in your .xaml file, which is Telerik.Data.Core

xmlns:grid="using:Telerik.UI.Xaml.Controls.Grid"
xmlns:dataCore="using:Telerik.Data.Core"

Then create sample data and add it to the datacontext of the DataGrid:

List<CustomData> data = new List<CustomData>
{
    new CustomData { Country = "Brazil", City = "Caxias do Sul"},
    new CustomData { Country = "Ghana", City = "Wa"},
    new CustomData { Country = "Brazil", City = "Fortaleza"},
    new CustomData { Country = "Italy", City = "Florence" },
    new CustomData { Country = "France", City = "Bordeaux" }, 
    new CustomData { Country = "Bulgaria", City = "Vratsa"},
    new CustomData { Country = "Spain", City = "Las Palmas"},
    new CustomData { Country = "France", City = "Le Mans" },
    new CustomData { Country = "Brazil", City = "Santos"},
    new CustomData { Country = "Ghana", City = "Ho"},
    new CustomData { Country = "Spain", City = "Malaga"},
    new CustomData { Country = "France", City = "Marseille" },
    new CustomData { Country = "Bulgaria", City = "Koynare" },
    new CustomData { Country = "Spain", City = "Valencia"},
    new CustomData { Country = "Ghana", City = "Kade" },
    new CustomData { Country = "Brazil", City = "Porto Alegre" }, 
    new CustomData { Country = "Bulgaria", City = "Byala Slatina"},
    new CustomData { Country = "Italy", City = "Naples" },
    new CustomData { Country = "Brazil", City = "Joinville" }, 
};
this.grid.ItemsSource = data;

CustomData is a custom class which defines our objects:

public class CustomData
{
    public string City { get; set; }
    public string Country { get; set; }
}
