            column.FieldName, System.ComponentModel.ListSortDirection.Ascending);
        grid.GroupSummarySortInfo.Add(sortInfo);
    }

<dxg:GridControl x:Name="grid">
    <dxg:GridColumn FieldName="UserName"/>
    <dxg:GridColumn FieldName="RegistrationDate" GroupIndex="0"/>
    <dxg:GridColumn FieldName="Age"/>
    <dxg:GridControl.View>
