推荐答案

有一个'极限[开始]，[长度]'就可以了你的PHP查询。穿上你的DataGrid的底部按钮，重新查询与相应的起点下一个查询。

Have your PHP query with a 'limit [start],[length]' on it. Put buttons on the bottom of your datagrid to requery with the appropriate starting point for the next query.

此外 - 我发现，试图读取超过超过几百记录确实减慢在我的Flex应用程序的渲染。 ESP，如果你所要求的一种或绘图任何类型的自定义控件。这只是我的$ 0.10，虽然。情况因人而异。

Also - I've found that trying to read in more than more than a few hundred records really slows down the rendering in my Flex apps. Esp if you are asking for a sort or drawing any sort of custom controls. That's just my $0.10 though. YMMV.
