我正在制作一个WPF应用程序，我有一个标签。当鼠标悬停弹出窗口上的标签触发器出现时。在这个弹出窗口中，我有一些带有不同动作的按钮。但是当我鼠标悬停在标签上时，弹出窗口出现但我无法通过触发器mouseleave消失之前使用弹出窗口。
这是我的XAML代码：
<Label x:Name="userLabel" Content="Label" Grid.Column="2" HorizontalAlignment="Left" Margin="404,31,0,0" VerticalAlignment="Top" Width="145" Foreground="White" MouseEnter="UserLabelMouseEnter" MouseLeave="UserLabelMouseLeave"/>
<Popup Name="UserMenuPopUp" PopupAnimation="Fade" Height="auto" Margin="0,0,0,0" AllowsTransparency="True" Placement="bottom" PlacementTarget="{Binding ElementName=userLabel}" StaysOpen="false">
<Border BorderThickness="1" Background="#EEEEEE" Height="160" HorizontalAlignment="Left" Width="195" RenderTransformOrigin="0.5,0.5">
<Grid>
<Button x:Name="profile" Content="profile" Margin="0,0,0,0" VerticalAlignment="Top" Height="40" BorderThickness="0" Click="ProfileBtn_Click" Foreground="White" HorizontalContentAlignment="Right">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="#282828"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#79B539"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
<Button x:Name="RentalPlans" Content="Rental plans" Margin="0,40,0,0" VerticalAlignment="Top" Height="40" BorderThickness="0" Click="RentalPlansBtn_Click" Foreground="White">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="#282828"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#79B539"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
<Button x:Name="MyCredits" Content="My credit cards" Margin="0,80,0,0" VerticalAlignment="Top" Height="40" BorderThickness="0" Click="MycreditsBtn_Click" Foreground="White">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="#282828"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#79B539"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
<Button x:Name="LogOut" Content="Log out" Margin="0,120,0,0" VerticalAlignment="Top" Height="40" BorderThickness="0" Foreground="White" Click="LogOuBtn_Click">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Setter Property="Background" Value="#282828"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="#79B539"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
</Grid>
</Border>
</Popup>
这是我的C＃代码：
private void UserLabelMouseEnter(object sender, MouseEventArgs e)
{
UserMenuPopUp.IsOpen = true;
}
private void UserLabelMouseLeave(object sender, MouseEventArgs e)
{
UserMenuPopUp.IsOpen = false;
}
答案 0 :(得分：0)
您可以将UserLabelMouseLeave代码移至Popup的MouseLeave事件。
