按钮单击在 WPF 中使用触发器更改 DataGrid 的可见性 [英] Button click changes visibility of a DataGrid with a Trigger in WPF

问题描述

我正在尝试找到某种方法，当单击按钮时更改其他控件的可见性，例如在 XAML 中带有触发器的 DataGrid.

Hi i am trying to find some way to when a button is clicked changes the visibility of other control, like a DataGrid with a Trigger in XAML.

该按钮仅将 DataGrid 的可见性更改为 Visible，它在代码隐藏中执行其他操作，但我认为这可以在带有触发器的样式中完成.

The button only changes the visibility of the DataGrid to Visible, it does other things in Code Behind, but this is something that i think that can be done in a Style with a Trigger.

我试图找到一个解决方案，似乎可以做到，但我不明白怎么做.

I tried to find a solution and it seems to be possible to do but i can't understand how.

提前致谢.

推荐答案

<Button Content="Button!">
    <Button.Triggers>
        <EventTrigger RoutedEvent="Button.Click">
            <BeginStoryboard>
                <Storyboard>
                    <ObjectAnimationUsingKeyFrames Storyboard.Target="{x:Reference dataGrid}"
                                                   Storyboard.TargetProperty="Visibility">
                        <DiscreteObjectKeyFrame KeyTime="0:0:0"
                                                Value="{x:Static Visibility.Visible}"/>
                    </ObjectAnimationUsingKeyFrames>
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </Button.Triggers>
</Button>

{x:Reference dataGrid} 引用名为 dataGrid 的 DataGrid，或者您可以使用 Storyboard.TargetName.如果要绑定或引用资源，通常会使用 Storyboard.Target 属性.

{x:Reference dataGrid} references a DataGrid with the name dataGrid, alternatively you could just use Storyboard.TargetName. You would normally use the Storyboard.Target property if you do binding or references to resources.
