什么是Silverlight中DataTrigger的替代品 [英] What is the replacement for DataTrigger in Silverlight

问题描述

这是我的情况.

我有2个属性.类型和状态.

I have 2 Properties. Type and State.

Type是具有3个值的枚举，例如，球，汽车，箭头. State是一个整数，可以接受3个状态值，例如-1、0、1.此外，每个状态值都有9张图片.

Type is an Enum with 3 values eg, ball, car, arrow. State is an int which would accept 3 state values eg., -1, 0, 1. Also, I have 9 images for each state values.

例如，如果我将类型选择为ball，将值选择为-1，则我想显示一个红色的球. 如果我选择type作为箭头，而value选择为1，我想显示一个向上箭头.等等，

Like, if I select type as ball and value as -1, I want to display a Red color ball. If I select type as arrow and value as 1, I want to display a up arrow. etc.,

我能够在WPF中做到这一点.我创建了3个带有空图像的DataTemplates.然后，我使用DataTrigger检查并更新所选StateValue的特定图像.

I'm able to do this in WPF. I created 3 DataTemplates with an empty Image. Then, I use DataTrigger to check and update the particular image for the selected StateValue.

但是，在Silverlight中，我该怎么做.我知道，我必须在VSM中执行此操作.但是，我想了解有关此(或任何可用替代方案)的更多详细信息.

But, in silverlight how can I do this. I know, I have to do it in VSM. But, I would like to know some more details regarding this (or) any alternatives available.

推荐答案

我只使用一个转换器，该转换器使用具有2个属性的对象并返回图像.纯XAML中的此类代码很痛苦，而且确实属于C#.

I'd just use a converter that takes your object with 2 properties and returns an image. Code like that in pure XAML is painful and really belongs in C#.
