绑定到伯爵在DataContext的项目 [英] Bind to Count of items in the DataContext

问题描述

我要绑定到我的DataContext中的项目数/数量。

I want to bind to the Count/amount of items within my DataContext.

我有一个对象，可以说其中有一个列表与LT人;地址＆gt; 作为一个属性。我想显示的地址量的那个人，即：5或6或其他情况而定。

I have an object, lets say person which has a List<address> as a property. I would like to display the amount of addresses for that person ie: 5 or 6 or whatever the case may be.

我试过 {绑定路径=＃地址.Count之间} 和其他几个人，但是，这并不似乎工作。

I've tried {Binding Path=address#.Count} and a few others but that doesnt seem to work.

任何帮助将是AP preciated，谢谢。

Any help would be appreciated, thanks.

推荐答案

您需要将名称绑定属性，而不是它的类型。

You need to bind the name of the property, not its type.

C＃：

public class Person
{
    ...
    public List<address> Addresses { get; set; }
    ...
}

XAML：

{Binding Addresses.Count}

假设你的的DataContext 是类型的对象人。
