将 IValueConverter 与 DynamicResource 一起使用? [英] Use IValueConverter with DynamicResource?

问题描述

在使用 DynamicResource 扩展时，有没有办法定义转换器?

Is there a way to define a converter when using the DynamicResource extension? Something in the lines of

<RowDefinition Height="{Binding Source={DynamicResource someHeight}, Converter={StaticResource gridLengthConverter}}" />

不幸的是，这给了我以下异常:

which unfortunately gives me the following excpetion:

DynamicResourceExtension"不能是在类型的源"属性上设置'捆绑'.一个'DynamicResourceExtension' 只能是在一个 DependencyProperty 上设置依赖对象.

A 'DynamicResourceExtension' cannot be set on the 'Source' property of type 'Binding'. A 'DynamicResourceExtension' can only be set on a DependencyProperty of a DependencyObject.

推荐答案

我知道我真的迟到了，但绝对有效的是使用 BindingProxy 像这样的动态资源

I know i am really late to this but what definitely works is using a BindingProxy for the DynamicResource like this

<my:BindingProxy x:Key="someHeightProxy" Data="{DynamicResource someHeight}" />

然后将转换器应用到代理

Then applying the converter to the proxy

<RowDefinition Height="{Binding Source={StaticResource someHeightProxy}, Path=Data, Converter={StaticResource gridLengthConverter}}" />
