How to bind to a StaticResource with a Converter?

wpfxamlstaticresourceconverters

提问by Ignacio Soler Garcia

I want to use a Converterto change the value of a StaticResourcebefore assigning it to a property. Is there a way to simulate a Bindingthat will just set the value of the StaticResourceafter converting it?

我想在将ConverteraStaticResource分配给属性之前使用 a更改 a 的值。有没有办法模拟 a在转换后Binding只设置它的值StaticResource

Something like {Binding Value={StaticResource myStatic}, Converter={StaticResource myConverter}}?

{Binding Value={StaticResource myStatic}, Converter={StaticResource myConverter}}什么?

回答by Marc

This works:

这有效:

<TextBox Text="{Binding Source={StaticResource myStatic}, 
                        Converter={StaticResource myConverter},
                        Mode=OneWay}" />

Note that you have to bind one way, because the binding requires a path attribute otherwise. This makes sense, as otherwise the binding would have to replace the whole resource...

请注意,您必须以一种方式绑定,否则绑定需要一个路径属性。这是有道理的,否则绑定将不得不替换整个资源......
