动画＆QUOT;本＆QUOT;和＆QUOT;其他＆QUOT;在WPF [英] Animating "this" and "other" in WPF

问题描述

考虑下列任何列表控制的DataTemplate：

Consider following DataTemplate in any List Control:

<DataTemplate>
    <TextBlock Text="{Binding}" />
</DataTemplate>

和动画如下：

<Window.Resources>
    <Storyboard x:Key="animExpand">
        <DoubleAnimation Storyboard.TargetProperty="Width" To="400" Duration="0:0:1" />
        <DoubleAnimation Storyboard.TargetProperty="Height" To="400" Duration="0:0:1" />
    </Storyboard>
    <Storyboard x:Key="animCollapse">
        <DoubleAnimation Storyboard.TargetProperty="Width" To="0" Duration="0:0:1" />
        <DoubleAnimation Storyboard.TargetProperty="Height" To="0" Duration="0:0:1" />
    </Storyboard>
</Window.Resources>

现在，我们希望：所有的TextBlocks的获得点击的时候，animExpand适用于它和所有的其他的TextBlock有一个animCollapse

Now we want: when any of TextBlocks get clicked, "animExpand" apply to it and all other TextBlock have a "animCollapse".

第一部分是简单（触发器会做），但问题是，如何让其他元素在这种情况下参加吗？

First part is straightforward (a Trigger would do it) but the question is how to make other elements take part in this scenario?

推荐答案

我想我会把一个布尔属性（IsExpanded或东西）在我的模型，然后创建一个datatrigger做基于价值的动画。当鼠标按下某个特定项目时，你不得不写的逻辑是，在该列表中的其他对象，则更新。

I think I would put an boolean property (IsExpanded or something) in my model and then create a datatrigger to do the animations based on that value. When a mousedown occurs on a particular item, you'd have to write the logic to updates that boolean in the other objects in the list.
