Answer 1

DataGridTextBoxColumn dgcstyle=new DataGridTextBoxColumn();
dgcstyle.FormatInfo = CultureInfo.CurrentCulture.NumberFormat;
dgcstyle.Format="C";

Answer 2

<asp:BoundColumn DataField="quantity" SortExpression="quantity" HeaderText="数量" DataFormatString="{0:###,###,#0}">
    <HeaderStyle Width="48px"></HeaderStyle>
    <ItemStyle HorizontalAlign="Right"></ItemStyle>
</asp:BoundColumn>主要是DataFormatString="{0:###,###,#0}

Answer 3

如果是模版列：
<asp:TemplateColumn HeaderText="已入&lt;br&gt;数量">
     <ItemTemplate>
<asp:TextBox id=txt_qty runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "qty","{0:###,###.00}")%>' >
</asp:TextBox>
     </ItemTemplate>
</asp:TemplateColumn>

DataGridTableStyle ts1 = new DataGridTableStyle();
ts1.MappingName = "CardFunction";
ts1.RowHeaderWidth=33;
// 1
DataGridTextBoxColumn TextCol = new DataGridTextBoxColumn();
TextCol.MappingName = "vipcard_sort";
TextCol.HeaderText = "卡别";
TextCol.Width = 105;
TextCol.NullText="";
                            TextCol.Format="0.00";
