templates - Silverlight 5：如何阻止组合框使用隐式数据模板

Question

喜欢新的隐式数据模板，但我刚刚遇到了问题。

我的 ComboBox 正在选择与 ItemsSources 类型匹配的 DataTemplate，而不是遵循我的 DisplayMemberPath 设置。有没有办法告诉控件不要查找 DataTemplates？

     <ComboBox DisplayMemberPath="DTO.Name" SelectedValue="{Binding DefaultModifierGroup, Mode=TwoWay}" 
ItemsSource="{Binding MenuRepository.ModifierGroups, Source={StaticResource Locator}}"/>

我认为您不能再使用 DisplayMemberPath 了。您可能需要在该组合框中创建新的数据模板。

        public IList<Person> Items { get; set; }

    }

    public class Person {

        public string Address { get; set; }
    }
