绑定实例作为资源 [英] Binding instance as resource

问题描述

我在xaml中有一个非常长且重复的绑定表达。我可以先在资源部分定义它，然后使用DynamicResource或StaticResource引用它吗？像这样的东西：

I have a very long and repeating binding expression in xaml. Can I first define it in resource section and then refer to it using DynamicResource or StaticResource? Something like:

<SomeControl Visibility="{DynamicResource BindingToParentDataContext}">

绑定表达式如下：

{Binding Path=DataContext.SomeProperty, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:SomeParentUserControl}}, Mode=OneWay, Converter={StaticResource booleanToVisibilityConverter}}

推荐答案

可行的方法是编写自定义标记扩展。 此

What might work is to write a custom markup extension. This should be a good reference.

但是除此之外，您不能像这样预定义标记。根据您的情况，您可以将其中一些放入数据模板中，以供重用。

But besides that, you can't "predefine" markups like that. Depending on your scenario, you might can put some of these into a datatemplate, which you can reuse.
