c# - WPF 中的菜单项被切断

Question

我正在开发一个 WPF，由于某种原因，我的菜单栏底部不断被切断。

我搜索并找到了一些答案，指出这是 .NET v3.5 框架中的一个错误，并且在 v4.0 中已修复。但是，我当前的项目设置是针对 .NET v4.5 设置的。

我的 WPF 预览看起来很完美。当我去运行该程序时，它就被切断了。由于我的代表较低，我无法显示图像，因此以下是链接:

任何帮助将不胜感激。

我认为您遇到的问题与您在某些对象上强制执行的边距和高度有关，这也将使重新调整窗口大小变得非常棘手，而结果又不会看起来有点奇怪。

此外，您的MenuItem设置了DockPanel.Dock，但似乎没有相应的DockPanel。

我已经用 Dockpanel 构建了一个快速变体，尽管您可以仅使用网格轻松地进行布局。

<Window x:Name="mainWindow" x:Class="Kewpon.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Kewpon" Height="585.455" Width="704.454">
<Grid>
    <DockPanel LastChildFill="True">
        <Menu x:Name="mainMenu" DockPanel.Dock="Top">
            <MenuItem Header="_File">
                <MenuItem Header="Open"/>
                <MenuItem Header="Save"/>
                <Separator/>
                <MenuItem Header="Close"/>
            </MenuItem>
            <MenuItem Header="Add">
                <MenuItem Header="Add Item" />
                <MenuItem Header="Add Coupon" />
            </MenuItem>
            <MenuItem Header="Remove" />
        </Menu>

        <ListView x:Name="itemListView" HorizontalAlignment="Left" Width="227" DockPanel.Dock="Left">
            <ListView.View>
                <GridView>
                    <GridViewColumn Width ="155" Header="Item Name" DisplayMemberBinding="{Binding itemName}"/>
                    <GridViewColumn Width ="60" Header="Cost" DisplayMemberBinding="{Binding retailCost}"/>
                </GridView>
            </ListView.View>
        </ListView>

        <UniformGrid Rows="4" DockPanel.Dock="Left" Height="200" VerticalAlignment="Top">
            <Label x:Name="totalLabel" Content="Total:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
            <Label x:Name="totalNoTaxLabel" Content="Total before tax:" HorizontalAlignment="Left"  VerticalAlignment="Top"/>
            <Label x:Name="totalNoTaxLabel_Copy" Content="Tax: " HorizontalAlignment="Left"  VerticalAlignment="Top"/>
            <Label x:Name="totalNoCouponLabel" Content="Total before coupons:" HorizontalAlignment="Left" VerticalAlignment="Top"/>
        </UniformGrid>
    </DockPanel> 
</Grid>
</Window>

这也值得快速浏览一下，以获取更多信息。
