弹出菜单无法处理MenuItem

本文关键字:处理 MenuItem 菜单 | 更新日期: 2023-09-27 18:24:24

我必须在单击MenuItem时显示弹出菜单。我已经为此写了以下代码:

<ContextMenu>
    <Border>
        <MenuItem Name="ack" Header="ACK" HorizontalAlignment="Center" Command="{Binding AcknowledgeCommand}"  Visibility="{Binding IsAcked, Converter={StaticResource showOnFalse}}" Click="MenuItem_Click_1"/>
    </Border>
    <Separator/>
    <Border>
        <MenuItem Header="Info" HorizontalAlignment="Center" Click="MenuItem_Click"/>
    </Border>
    <Separator/>
    <Border>
        <MenuItem Header="Goto" HorizontalAlignment="Center"/>
    </Border>
    <Popup Name="infoPopup" Placement="Mouse" HorizontalOffset="-100" VerticalOffset="-100" AllowsTransparency="True" StaysOpen="True">
        <Alarms:UserControl_MYUC DataContext="{Binding TopMost}" Background="{DynamicResource DetailPanelCompartmentTitleBg}" BorderBrush="{DynamicResource SecWindowBtnBorder}"/>
    </Popup>
</ContextMenu>

点击菜单项,我已经写了以下代码:

private void MenuItem_Click(object sender, RoutedEventArgs e)
{
    infoPopup.Visibility = System.Windows.Visibility.Visible;
    infoPopup.IsOpen = true;
}

我可以在点击信息按钮时看到弹出窗口,但弹出窗口会在一秒钟内出现。我希望它是可见的,直到用户点击其他区域或弹出失去焦点。请建议该怎么做。

StaysOpenOnClick="True"应用于MenuItem。

请使用StaysOpen布尔值来定义您想要的内容。

myPopup.StaysOpen = true;
