如何使用C＃/ WPF动画上的MouseEnter和鼠标离开事件列表框的项目？ [英] How to animate ListBox Items on MouseEnter and MouseLeave events using C#/WPF?

问题描述

我无法捕捉/触发OnMouseEnter在或通过C＃code列表项OnMouseLeave在事件。需要明确的是，我并不需要一个OnSelectedItem事件。

I can't capture/trigger OnMouseEnter or OnMouseLeave events through C# code for list items. To be clear, I don't need an OnSelectedItem event.

我想要做的是能够处理ListBoxItem的的OnMouseEnter在和OnMouseLeave在事件，将启动DoubleAnimation是为ListBoxItem的 - 我想扩大在它的MouseEnter字体和还原到鼠标离开原来的大小。

What I want to do is to be able to handle the OnMouseEnter and OnMouseLeave events for ListBoxItem which will start the DoubleAnimation for that ListBoxItem - I want to enlarge its font on MouseEnter and restore to original size on MouseLeave.

任何想法？谢谢你。

推荐答案

像这样的东西（如ListBox的DataTemplate中的一部分）：

Something like this (as part of the ListBox's DataTemplate):

<DataTemplate.Triggers>
    <EventTrigger
        SourceName="BorderControl"
        RoutedEvent="TextBlock.MouseEnter">
        <BeginStoryboard>
            <Storyboard>
                <ColorAnimation Storyboard.TargetName="BorderControl"
                    Storyboard.TargetProperty="Background.Color"
                    To="DarkRed" Duration="00:00:00.2" />
            </Storyboard>
        </BeginStoryboard>
    </EventTrigger>
    <EventTrigger
        SourceName="BorderControl"
        RoutedEvent="TextBlock.MouseLeave">
        <BeginStoryboard>
            <Storyboard>
                <ColorAnimation Storyboard.TargetName="BorderControl"
                    Storyboard.TargetProperty="Background.Color"
                    To="WhiteSmoke" Duration="00:00:00.2" />
            </Storyboard>
        </BeginStoryboard>
    </EventTrigger>
</DataTemplate.Triggers>
