我正在尝试如下设置我的组合框样式。
下拉列表显示正确的名称列表，但选中后，namespace.classname将显示为组合文本而不是所选名称。
我有以下组合框的样式和声明。任何人都知道我错了什么？谢谢！

编辑：
谢谢伊恩。
这是我使用的数据。只是将列表分配给组合框项目源的简单操作。选择任何名称时，不会显示“Eric”，“Stan”或“Kyle”，而是显示“WpfCosmo.Person”。
在我的ControlsPage.xaml中：
<ComboBox Height="22" Margin="0,0,0,5" x:Name="comboBox" DisplayMemberPath="Name" SelectedIndex="-1" />
在我的代码背后：
public partial class ControlsPage : Page
{
public ControlsPage()
{
InitializeComponent();
comboBox.ItemsSource = Person.GetList();
}
}
public class Person
{
public string Name { get; set; }
public string Surname { get; set; }
public static List<Person> GetList()
{
List<Person> SouthPark = new List<Person>() {
new Person() { Name = "Eric", Surname="Cartman" },
new Person() { Name = "Stan", Surname="Marsh" },
new Person() { Name = "Kyle", Surname="Broflovski" },
new Person() { Name = "Kenny", Surname="McCormick" },
new Person() { Name = "Bebe", Surname="Stevens" },
new Person() { Name = "Clyde", Surname="Donovan" },
new Person() { Name = "Craig", Surname="Tucker" },
new Person() { Name = "Jimmy", Surname="Vulmer" },
new Person() { Name = "Pip", Surname="Pirrup" },
new Person() { Name = "Token", Surname="Black" },
new Person() { Name = "Tweek", Surname="Tweak" },
new Person() { Name = "Wendy", Surname="Testaburger" },
new Person() { Name = "Annie", Surname="Polk" },
new Person() { Name = "Randy", Surname="Marsh" },
new Person() { Name = "Sharon", Surname="Marsh" },
new Person() { Name = "Shelley", Surname="Marsh" },
new Person() { Name = "Marvin", Surname="Marsh" },
new Person() { Name = "Jimbo", Surname="Kern" },
new Person() { Name = "Gerald", Surname="Broflovski" },
new Person() { Name = "Sheila", Surname="Broflovski" },
new Person() { Name = "Ike", Surname="Broflovski" },
new Person() { Name = "Kyle", Surname="Schwartz" },
new Person() { Name = "Liane", Surname="Cartman" },
new Person() { Name = "Stuart", Surname="McCormick" },
new Person() { Name = "Carol", Surname="McCormick" },
new Person() { Name = "Kevin", Surname="McCormick" },
new Person() { Name = "Stephen", Surname="Stotch" },
new Person() { Name = "Linda", Surname="Stotch" },
new Person() { Name = "Richard", Surname="Tweak" }
};
return SouthPark;
}
}

尝试删除这部分风格：
Content="{TemplateBinding SelectionBoxItem}"
ContentTemplate="{TemplateBinding SelectionBoxItemTemplate}"

我知道这个话题很老，但最近我遇到了同样的问题。我想为我的组合框设置一个自定义样式，所以我开始在Visual Studio中提取默认模板来修改它。但是当我这样做时，我的组合框架不再起作用了。
经过对Google的一些研究后，我在这里找到了一个解决方案：StackOverFlow : Custom Template for ComboBox ignores use of DisplayMemberPath
问题来自Visual Studio模板提取器（我相信它与Blend的相同之处）忘记了Content Presenter中的属性：
ContentTemplateSelector =“{TemplateBinding ItemTemplateSelector}”
这个简单的属性为我解决了这个问题。
希望这可以帮助别人。
