我正在开始 Caliburn Micro 开发,并且我想到了一种架构,其中视图模型具有由 MEF 注入的属性,这些属性是其他视图模型。这样我就可以在视图中使用 contentcontrols 来按我想要的方式定位它们。
public class ContactsProfileViewModel : Conductor<IContentItem>, IContactsModuleViewModel, IModule, IPartImportsSatisfiedNotification
{
private string name;
private string nameCaption;
private ISingleLineTextContentItem firstName;
private ISingleLineTextContentItem lastName;
public ContactsProfileViewModel()
{
this.DisplayName = "Contact Tab";
}
public string Name
{
get
{
return this.name;
}
set
{
this.name = value;
this.NotifyOfPropertyChange(() => Name);
}
}
public string NameCaption
{
get
{
return this.nameCaption;
}
set
{
this.nameCaption = value;
this.NotifyOfPropertyChange(() => NameCaption);
}
}
[Import(typeof(ISingleLineTextContentItem))]
public ISingleLineTextContentItem FirstName
{
get { return this.firstName; }
set
{
this.firstName = value;
this.NotifyOfPropertyChange(() => FirstName);
}
}
[Import(typeof(ISingleLineTextContentItem))]
public ISingleLineTextContentItem LastName
{
get { return this.lastName; }
set
{
this.lastName = value;
this.NotifyOfPropertyChange(() => LastName);
}
}
SingleLineTextContentItem 的视图模型如下所示:
[Export(typeof(ISingleLineTextContentItem))]
[PartCreationPolicy(CreationPolicy.NonShared)]
public class SingleLineTextContentItemViewModel : PropertyChangedBase, ISingleLineTextContentItem
{
private string textBoxText;
private string caption;
public string TextBoxText
{
get { return textBoxText; }
set
{
textBoxText = value;
this.NotifyOfPropertyChange(() => TextBoxText);
}
}
public string Caption
{
get { return caption; }
set
{
this.caption = value;
this.NotifyOfPropertyChange(() => Caption);
}
}
}
现在,我需要一种以双向方式将 NameCaption 属性绑定到 Caption 属性的方法。那可能吗?我是在正确的轨道上还是有更好的方法来做到这一点?
谢谢,
罗兰
