我在使用具有 IsCheckable=True 的 MenuItem 对象时遇到了一个奇怪的问题 - 一张截图值一千字:
这看起来很像
那么,我如何到达那个黑匣子,并让它成为,比如说,GhostWhite?
解决方案为我工作.
按照您引用的链接中的说明导出模板.
将该样式应用到 MneuItems.
<按钮内容="一个"/><按钮内容="两个"/><菜单><MenuItem Header="Markets" Style="{DynamicResource MenuItemStyle1}"><MenuItem IsCheckable="True" Header="British" Style="{DynamicResource MenuItemStyle1}"/><MenuItem IsCheckable="True" Header="Irish" Style="{DynamicResource MenuItemStyle1}"/></菜单项></菜单></工具栏>将模板中的 Background 更改为 Yellow 如下:

have IsCheckable=True - a screenshot is worth a thousand words:
This looks very much like Check Mark Showing as a Black Box in Menu, except the accepted answer there, unless I misread it badly, suggests to tweak ToolBar.MenuStyleKey, which doesn't seem to be tweaking the right thing at all:
<Style x:Key="{x:Static ToolBar.MenuStyleKey}" TargetType="Menu"> <Setter Property="Background" Value="Yellow" /> </Style>So, how do I get to that black box, and make it, say, GhostWhite?
解决方案Works for me.
Exported the template per the instructions in the link you referenced.
Applied that style to the MneuItems.
<ToolBar> <Button Content="One"/> <Button Content="Two"/> <Menu> <MenuItem Header="Markets" Style="{DynamicResource MenuItemStyle1}"> <MenuItem IsCheckable="True" Header="British" Style="{DynamicResource MenuItemStyle1}"/> <MenuItem IsCheckable="True" Header="Irish" Style="{DynamicResource MenuItemStyle1}"/> </MenuItem> </Menu> </ToolBar>Changed Background to Yellow in the template as such:
<Border x:Name="GlyphPanel" BorderBrush="#80DADADA" BorderThickness="1" Background="Yellow" Height="20" Margin="0,1" Visibility="Hidden" Width="20">Just to make this example totally complete, below is the template that I exported:
