如何删除ListView的添加项动画? [英] How to remove ListView's add item animation?

问题描述

我有一个ListView，我编辑了它的ItemContainerStyle以修改某些样式，但是我不知道如何在添加项目时删除该烦人的动画.

I have a ListView and I edited its ItemContainerStyle to modify some style but I don't know how to remove that annoying animation when you add an item.

使用ItemsControl，当您添加新项目时，它会立即显示，没有任何动画.

With an ItemsControl, when you add a new item, it appears instantly, without any animation.

使用ListView，该项目需要一段时间，然后开始显示动画.

With ListView, the item takes a while and then, it starts an animation to show up.

我只想删除该add animation，当我单击Add item时，它会立即显示，没有多余的东西.

I just want to remove that add animation and when I click on Add item it appears instantly, no extra stuff.

我认为它应该属于ItemContainerStyle，但是即使我注释掉了所有视觉状态动画，并且仍然存在.我错过了一些东西.

I think that it should belong to ItemContainerStyle but even I commented out all visualstate animations and is still there. I'm missing something out.

推荐答案

这些动画称为过渡，它们是ListViewStyle的一部分.要更改它，请在设计器中的ListView控件上单击鼠标右键，然后选择Edit Template> Edit a Copy....这会将内置样式添加到您的XAML中.

These animations are called transitions and they are part of ListViewStyle. To change it right click on ListView control in the designer and select Edit Template > Edit a Copy.... This will add the built-in style to your XAML.

样式的以下部分对您很感兴趣:

The following part of the style is of interest to you:

<Setter Property="ItemContainerTransitions">
    <Setter.Value>
        <TransitionCollection>
            <AddDeleteThemeTransition/>
            <ContentThemeTransition/>
            <ReorderThemeTransition/>
            <EntranceThemeTransition IsStaggeringEnabled="False"/>
        </TransitionCollection>
    </Setter.Value>
</Setter>

我不确定您到底不喜欢哪个动画，但是请尝试从TransitionCollection中删除AddDeleteThemeTransition和/或EntranceThemeTransition.它应该可以解决问题.

I'm not sure which animation exactly you dislike but try removing AddDeleteThemeTransition and/or EntranceThemeTransition from TransitionCollection. It should do the trick.

别忘了确保将修改后的样式应用于所需的ListView.

Don't forget to make sure the modified style is applied to the desired ListView.
