限制项目控件中显示的行数 [英] Limit the number of rows displayed in Items control

问题描述

是否有一种方法来限制在项目控件中显示的行数. ?

Is there a way to limit the number of rows that get displayed in items control. ?

我有一个绑定到Items控件的可观察字符串集合.我想将要显示的行数限制为仅一.该集合可以有多个.

I have a observable collection of strings which are bound to Items control. I want to limit the number of rows to display to only one. The collection can have more than one.

谢谢

推荐答案

假设您的ItemsSource设置为MyObservableCollection.

好吧，如果更改ItemsSource以使其指向MyOneItemCollection怎么办?

Well, what if you change your ItemsSource so that it is pointing a MyOneItemCollection instead?

然后，只需使用LINQ来执行以下操作:

Then, just use LINQ to do something like this:

using System.Linq;
MyOneItemCollection = MyObservableCollection.First();

或

using System.Linq;
MyOneItemCollection = MyObservableCollection.Single(item => item.Id = MyId);
