MOSS 2010:为视图添加参数显示的功能

我们现在还可以根据一些参数来决定某个视图显示的数据。例如我们需要实现这样的场景：用户可以通过在地址栏中添加一些特殊的参数来对数据进行筛选

首先仍然是来看一下效果先

下面这个页面地址是：http://nymoss2010:45223/sites/dev/Lists/New%20Toy%20Ideas/AllItems.aspx?InitialTabId=Ribbon%2EListItem&VisibilityContext=WSSTabPersistence

下面这个地址是

http://nymoss2010:45223/sites/dev/Lists/New%20Toy%20Ideas/AllItems.aspx?InitialTabId=Ribbon%2EListItem&VisibilityContext=WSSTabPersistence&existing=1

我们看到第二个界面上没有数据的.而他们地址栏的区别就在于第二个地址的最后面有&exising=1，这表示要查找那些Existing Product为true（或1）的记录

我们是如何让地址栏的这些参数影响到视图的呢？

就是这么容易。这让我想起了我们刚学ASP.NET 2的时候，不是有一个SqlDataSource控件么，也有这个特性的。

难道他们之间有什么千丝万缕的关系么？大家根据下面的这些文本先琢磨一下
