以编程方式将List列表绑定到ListBox [英] Programmatically binding List to ListBox

问题描述

例如我有以下非常简单的窗口：

Lets say for instance i have the following extremely simple window:

<Window x:Class="CalendarGenerator.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="447">
    <Grid>
        <ListBox Margin="12,40,0,12" Name="eventList" HorizontalAlignment="Left" Width="134" />
    </Grid>
</Window>

一个简单的列表定义为：

And a simple list defined as:

List<String> ListOfNames = new List<String>();

让我们假设列表中有几个名字。我将如何使用尽可能多的代码隐藏列表到ListBox？

And lets assume that the list has several names in it. How would i go about binding the List to the ListBox using as much code-behind as possible?

推荐答案

首先你需要给你的ListBox一个名字，以便它可以从你的代码访问（编辑我注意到你已经这样做了，所以我将更改我的示例ListBox的名称来反映你的）：

First you'd need to give your ListBox a name so that it's accessible from your code behind (edit I note you've already done this, so I'll change my example ListBox's name to reflect yours):

<ListBox x:Name="eventList" ... />

那么就像设置ListBox的 ItemsSource 属性到您的列表：

Then it's as simple as setting the ListBox's ItemsSource property to your list:

eventList.ItemsSource = ListOfNames;

由于您已将ListOfNames对象定义为列表< String> ; ，ListBox将不会自动反映对列表所做的更改。要使WPF的数据绑定对列表中的更改做出反应，请将其定义为 ObservableCollection < String> 。

Since you've defined your "ListOfNames" object as a List<String>, the ListBox won't automatically reflect changes made to the list. To get WPF's databinding to react to changes within the list, define it as an ObservableCollection<String> instead.
