已在编译时检测 XAML 中损坏的绑定 [英] Detect broken bindings in XAML already at compile time

问题描述

我认为这是一个简单而频繁的场景 - 您在 XAML 中将依赖属性绑定到视图模型中的属性，然后在视图模型中重命名该属性，而忘记在 XAML 中重命名它.绑定也被破坏了.

It is a simple and frequent, I think, scenario - you bind in XAML a dependency property to property in the viewmodel and later rename the property in viewmodel and forget to rename it in XAML. So is the binding broken.

有没有办法在编译时就检测到这种破坏的绑定?

Is there a way to detect such a broken bindings already at compile time?

推荐答案

您可以将 VM 类添加到您的绑定行中:

you could add the VM-class to your Binding line this:

<DataGrid ItemsSource="{Binding Path=(viewModels:MyViewModel.MyItemsSource)}" />

与:

namespace ViewModels{
    public class MyViewModel{
        public ICollectionView MyItemsSource {get; set;}
    }
}

这向您展示了 DesignTime 的 BindingErrors
