急Gridview不分页兑现pagesize功能

急急急：：：Gridview不分页实现pagesize功能？
用一个DataView和SqlDataSource配套使用显示数据，想不分页，但只显示数据库最后的8条记录。怎么实现呢？？
  <asp:SqlDataSource ID="SqlDataSource3" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString31 %>"
  ProviderName="<%$ ConnectionStrings:ConnectionString31.ProviderName %>" SelectCommand='SELECT TOP 8 * FROM "INDEX_NEWS" ORDER BY "NEWS_ID" DESC'>
  </asp:SqlDataSource>


  而当我改成SelectCommand='SELECT TOP 8 * FROM "INDEX_NEWS" ORDER BY "NEWS_ID" DESC'
的时候就出错

------解决方案--------------------------------------------------------
单双引号换下行吗？

还是自己写的顺手，比较怪

SelectCommand='SELECT TOP 8 * FROM INDEX_NEWS ORDER BY NEWS_ID DESC'
