编程结合清单列表框 [英] Programmatically binding List to ListBox

问题描述

比方说，比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>

和定义为一个简单的列表：

And a simple list defined as:

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

和让我们假设该列表中有好几个名字。我将如何去使用尽可能多的$ C $列表绑定到ListBox C-后面越好？

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

首先你需要给你的列表框的名称，以便它是从后面（的修改的我注意到您的code访问你已经做到了这一点，所以我会改变我的例子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" ... />

然后，它与设定ListBox的<一个简单href=\"http://msdn.microsoft.com/en-us/library/system.windows.controls.itemscontrol.itemssource.aspx\">ItemsSource属性列表：

eventList.ItemsSource = ListOfNames;

既然已经定义了你ListOfNames对象作为列表与LT;弦乐＆GT; ，列表框不会自动反映到列表中所做的更改。为了让WPF的数据绑定反应到列表中的更改，将其定义为<一个href=\"http://msdn.microsoft.com/en-us/library/ms668604.aspx\">ObservableCollection<$c$c><String>来代替。

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.
