如何将xaml属性绑定到另一个类中的静态变量? [英] How can I bind a xaml property to a static variable in another class?

问题描述

我有这个xaml文件，我试图在其中将文本块背景绑定到另一个类中的静态变量，该如何实现呢?

I have this xaml file in which I try to bind a Text-block Background to a static variable in another class, how can I achieve this ?

我知道这可能很愚蠢，但是我刚从Win-forms搬走了，感到有点失落.

I know this might be silly but I just moved from Win-forms and feeling a little bit lost.

这是我的意思:

<TextBlock Text="some text"
           TextWrapping="WrapWithOverflow"
           Background="{Binding Path=SomeVariable}" />

推荐答案

首先，您无法绑定到变量.您只能从XAML绑定到 properties .对于绑定到静态属性，您可以采用这种方式(例如，您要绑定 TextBlock 的 Text 属性)-

First of all you can't bind to variable. You can bind only to properties from XAML. For binding to static property you can do in this way (say you want to bind Text property of TextBlock) -

<TextBlock Text="{Binding Source={x:Static local:YourClassName.PropertyName}}"/>

其中 local 是您的类所在的名称空间，您需要在上面的xaml文件中像下面这样声明-

where local is namespace where your class resides which you need to declare above in xaml file like this -

xmlns:local="clr-namespace:YourNameSpace"
