Display custom object data to ListBox WPF
提问by Sachin Gaur
I have a ListBox in WPF application as :
我在 WPF 应用程序中有一个 ListBox 为：
<ListBox HorizontalAlignment="Left" Margin="16,37,0,16" Name="lbEmpList" Width="194" SelectionChanged="lbEmpList_SelectionChanged" FontSize="12" SelectionMode="Single">
</ListBox>
I have three buttons: Add, Remove and Update that will add, remove and update items to the list box. I am adding Items to the ListBox my custom class object names objEmployee.
This custom class contains few properties: Id, Name, Address.
But, when I add the object to ListBox, then it will display items as
我有三个按钮：添加、删除和更新，它们将向列表框中添加、删除和更新项目。我正在将 Items 添加到我的自定义类对象名称objEmployee的 ListBox 中。这个自定义类包含几个属性：Id、Name、Address。
但是，当我将对象添加到 ListBox 时，它会将项目显示为
<Namespace Name>.<Custom Object name>
How can I bind any of the object property to this ListBox at Design or run time to acheive my functionality?

Couple of options:
几个选项：
The first, easiest option is to set the ListBox's DisplayMemberPathproperty to a property of your custom object. So if your Employee class has a LastName property you could do this:
第一个最简单的选项是将 ListBox 的DisplayMemberPath属性设置为自定义对象的属性。因此，如果您的 Employee 类具有 LastName 属性，您可以这样做：
<ListBox DisplayMemberPath="LastName" ... />
If you want more control over the data that's displayed for each item (including custom layout etc) then you'll want to define a DataTemplatefor each item in your ListBox. The easiest way to do this is by simply setting the ListBox's ItemTemplateproperty:
如果您想更好地控制为每个项目（包括自定义布局等）显示的数据，那么您需要为ListBox 中的每个项目定义一个DataTemplate。最简单的方法是简单地设置 ListBox 的ItemTemplate属性：
<ListBox ...>
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding FirstName}" />
<TextBlock Text="{Binding LastName}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
