WP7 绑定到局部变量 [英] WP7 Binding to Local Variable

问题描述

我有一个 UI 元素，我想根据页面中的局部变量设置其颜色(实际上在模块中，但我可以将其移动到页面).

I have a UI element whose color I'd like to set based on a local variable in the page (well actually in a module, but I can move it to the page).

我在 WPF 中看到，可以通过将变量设为属性并使用 FindAncestor 将 RelativeSource 绑定到父类来将 UI 元素绑定到局部变量:

I see in WPF one can bind a UI element to a local variable by making the variable a property and setting the binding RelativeSource to the parent class using FindAncestor:

WPF 绑定到局部变量

遗憾的是 Silverlight 似乎不支持 FindAncestor 模式.

Unfortunately Silverlight doesn't seem to support FindAncestor mode.

任何可能的解决方案，或者我是否必须为这个变量创建一个自定义类的实例?

Any possible solution, or do I have to create an instance of a custom class and such just for this one variable?

推荐答案

在过去的几周里，我从 Silverlight 跳到 WPF 很多，所以下面的想法可能会也可能不会.

Ive been jumping from Silverlight to WPF a lot over the last few weeks, so the following idea may or may not fly.

您的页面是否设置了 name 属性?如果没有，设置它 (x:Name="MyPage").

Does your page have the name property set on it? If not, set it (x:Name="MyPage").

那么你可以这样做:

Fill="{Binding ElementName=MyPage, Path=MyProperty}"

试试看(就在我的头顶)

Give that a try (just off the top of my head)
