Question

我有一个看起来像这样的窗口：

<vk:VirtualKeyboard x:Class="Hurst.VirtualKeyboard.QwertyVirtualKeyboard"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:vk="clr-namespace:Hurst.VirtualKeyboard"
xmlns:vm="clr-namespace:Hurst.VirtualKeyboard.ViewModels"
DataContext="{DynamicResource keyboardViewModel}"
Height="400" Width="1280" d:DesignHeight="300" d:DesignWidth="710" 
x:Name="VK"
>

<vk:VirtualKeyboard.Resources>
    <ObjectDataProvider x:Key="keyboardViewModel" ObjectType="{x:Type vm:KeyboardViewModel}" />
</vk:VirtualKeyboard.Resources>

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="43"></RowDefinition>
        <RowDefinition Height="*"></RowDefinition>
    </Grid.RowDefinitions>

    <Button Grid.Row="0" Foreground="White" Margin="0 3 20 0" Background="#006AB6" BorderThickness="0" Command="{Binding CloseKeyboardCommand}" FontSize="25" Content="Close" VerticalContentAlignment="Center"/>

    <Border Grid.Row="1" BorderBrush="#006AB6" BorderThickness="5">
            some content here
    </Border>
</Grid>

QwertyVirtualKeyboard是一个扩展VirtualKeyboard类的类，它扩展了Window类。

我面临的问题是：当我点击“关闭”按钮时，有时会触发“关闭”命令，有时不会触发。悬停时会发生同样的事情 - 有时会触发悬停，有时则不会。我注意到当鼠标位于按钮的底部时，悬停并单击它们应该工作，但当我将鼠标移动到按钮的上半部分时，它们不会。我在这里缺少什么？

按钮事件有时会触发，有时不会
