限制对一个ASP.NET的ListView结果数 [英] Limit the number of results on a ASP.NET ListView

问题描述

我必须绑定到一个泛型列表集合一个ListView。

I have a ListView bound to a Generic List collection.

我需要能够限制势必像5项的数目，并显示在模板的more按钮。

I need to be able to limit the number of items bound to something like 5, and show a more button in the template.

我可以处理DataBinding事​​件，并删除列表＆LT的最后几个项目;>，但一些事感觉不对。我还可以在列表中未限制在5事前，因为我需要知道，有超过5个，以显示更多按钮。

I can handle the DataBinding event, and remove the last few items in the List<>, but something about that doesn't feel right. I also can't limit the list to 5 beforehand, because I need to know that there are more than 5, to show the "more" button.

任何想法？谢谢！

推荐答案

数据绑定列表，以

yourlist.Take(5);

（即LINQ的运营商），但执行检查根据原名单上的更多的按钮。

(i.e. the LINQ operator), but perform the check for the more button based on the original list.
