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

问题描述

比方说，例如，我有一个非常简单的窗口:

Let's 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将 List 绑定到 ListBox?

And let's 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，您需要为 ListBox 命名，以便可以从您的代码背后访问它(编辑我注意到您已经已经这样做了，所以我将更改我的示例 ListBox 的名称以反映您的名称):

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" ... />

然后就像设置 ListBox 的 ItemsSource 属性添加到您的列表中:

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 List，ListBox 不会自动反映对列表所做的更改.要让 WPF 的数据绑定对列表中的更改做出反应，请将其定义为 ObservableCollection 代替.

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.
