设置虚拟机继承屏幕时的Caliburn.Micro，覆盖视图中的标题字段 [英] Caliburn.Micro when setting VM to inherit Screen, overrides title field in View

问题描述

如果我有这样的ViewModel：

If I have a ViewModel like so:

 public class ViewModel : IPropertyChangeBase, IViewModel
 {
 }

我在视图的xaml中设置的标题属性必定会正确显示。

The "Title" property I set in the xaml of the view it's bound to properly shows.

如果我让ViewModel从Screen继承，则标题中显示的是ViewModel的完整类型名称，例如 MarksProject.ViewModels.ViewModel。这会显示在窗口的标题上。

If I have the ViewModel inherit from Screen instead what shows up in the title is the complete type name of the ViewModel, like "MarksProject.ViewModels.ViewModel." This shows up on the window's title.

 //View Title property being overriden.
 public class ViewModel : Screen, IViewModel
 {
 }

推荐答案

屏幕定义了属性DisplayName，Caliburn.Micro使用该属性自动填充标题。只需在构造函数中这样设置即可：

Screen defines a property DisplayName that Caliburn.Micro uses to automatically populate headers. Just set that in the constructor like this:

public ViewModel() {
    this.DisplayName = "MyTitle";
}

您将获得标题-并在此过程中保存了一个属性;）

And you'll have your title back - and saved a Property in the process ;)
