根据类型动态更改XAML绑定 [英] Dynamically change XAML binding based on type

问题描述

我有一个对象列表，这些对象被用作DataGrid的源。该对象列表是基类类型，其中有2个或更多继承类型。我试图绑定到基类的属性以在DataGrid列中显示为值。子类具有可供我显示的不同属性，所以我的问题是，XAML是否可以根据所指向的类型动态更改绑定的值？我曾考虑过可能使用转换器执行此操作，但是如果我理解正确，那么我将不得不为需要绑定到的每个子类属性编写一个不同的转换器。任何意见或建议，表示赞赏。谢谢

I have a list of objects that is being used as the source for a DataGrid. This list of objects is a base class type, of which there are 2 or more inherited types. I am trying to bind to properties of the base class to display as values in the columns of the DataGrid. The subclasses have different properties available to them which I would like to be able to display, so my question is, does XAML have a way to dynamically change the value of a binding based on the type that is being pointed to? I have thought about potentially doing this with a converter, but if I understand correctly, then I would have to write a different converter for each subclass property that I need to bind to. Any advice or suggestions are appreciated. Thanks
