在编译时已在XAML中检测到已断开的绑定 [英] Detect in XAML broken bindings already at compile time

问题描述

我认为这是一个简单且频繁的场景-您在XAML中将一个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，而忘记了在XAML中对其重命名.绑定也被破坏了.

It is a simple and frequent, I think, scenario - you bind in XAML a dependent 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.

有没有一种方法可以在编译时检测到这种已损坏的绑定?

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

推荐答案

您可以通过以下方式将VM类添加到绑定行:

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

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

具有:

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

这向您显示了设计时的BindingErrors

This shows you BindingErrors at DesignTime
