DevExpress 10.2中AspxGridView显示问题

我在页面中使用了一个AspxGridView控件，现在想要在预算金额这列更改下显示，就是按金额三分位进行显示，譬如说1234显示成1,234，请问该如何来设置？代码如下：
 <dx:ASPxGridView ID="grid" ClientInstanceName="grid" runat="server" KeyFieldName="ID"
        Width="100%" AutoGenerateColumns="False" ClientIDMode="AutoID">
        <Columns>
           <dx:GridViewDataColumn FieldName="Quantity" Caption="数量" Width="80" VisibleIndex="0"
                HeaderStyle-HorizontalAlign="Center" CellStyle-HorizontalAlign="Left" EditFormSettings-Visible="False">
                <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
                <CellStyle HorizontalAlign="Left">
                </CellStyle>
            </dx:GridViewDataColumn>            
            <dx:GridViewDataColumn FieldName="BudgetAmount" Caption="预算金额" Width="" VisibleIndex="1"
                HeaderStyle-HorizontalAlign="Center" CellStyle-HorizontalAlign="Left" EditFormSettings-Visible="False">
                <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
                <CellStyle HorizontalAlign="Left">
                </CellStyle>
            </dx:GridViewDataColumn>
</Columns>
</dx:ASPxGridView>
