WPF MouseLeftButtonUp 不触发 [英] WPF MouseLeftButtonUp Not Firing

问题描述

当我使用 MouseUp 事件时，我可以通过鼠标右键单击来触发它.但是 MouseLeftButtonUp 不会被任何一次点击触发！

When I use the MouseUp event, I can get it to fire with a mouse right-click. But MouseLeftButtonUp won't fire with either click!

<Button MouseLeftButtonUp="btnNewConfig_MouseUp"  Name="btnNewConfig">
    <StackPanel Orientation="Horizontal">
        <Image Source="Icons
ew.ico" Height="24" Width="24" Margin="5"/>
        <TextBlock VerticalAlignment="Center">New</TextBlock>
    </StackPanel>
</Button>

我知道这很可能很简单.感谢您的帮助！

I know this is most likely something simple. Thanks for the help!

推荐答案

看起来 Button 控件正在吃掉那个事件 因为 Button.Click 实际上是 Button.Click 的组合code>LeftButtonDown 事件和 LeftButtonUp 事件.

Looks like Button control is eating up that event Since Button.Click is actually a combination of LeftButtonDown event and LeftButtonUp event.

但是您可以订阅 Button 而不是 LeftButtonUp 上的隧道事件 PreviewMouseLeftButtonUp.

But you can subscribe to the tunneled event PreviewMouseLeftButtonUp on the Button instead of LeftButtonUp.
