        grid.ItemsSource = AccountList.GetData();
        SortGroupsBySummary(view.GroupedColumns[0]);

        GridGroupSummarySortInfo sortInfo = new GridGroupSummarySortInfo(grid.GroupSummary[0],
            column.FieldName, System.ComponentModel.ListSortDirection.Ascending);
        grid.GroupSummarySortInfo.Add(sortInfo);

    Public Sub New()
        Me.InitializeComponent()
        Me.grid.ItemsSource = AccountList.GetData()
        Me.SortGroupsBySummary(Me.view.GroupedColumns(0))
    End Sub

    Private Sub SortGroupsBySummary(ByVal column As GridColumn)
        Dim sortInfo As GridGroupSummarySortInfo = New GridGroupSummarySortInfo(Me.grid.GroupSummary(0), column.FieldName, System.ComponentModel.ListSortDirection.Ascending)
        Me.grid.GroupSummarySortInfo.Add(sortInfo)

    <dxg:GridControl.View>
        <dxg:TableView x:Name="view" AutoWidth="True"/>

    <dxg:GridControl.GroupSummary>
        <dxg:GridSummaryItem FieldName="Age" SummaryType="Max"/>
