C＃：调试时未显示菜单项

Question

So I have added a "Menu" item to my program and though properties:

IsEnabled: (is checked)
visibility: Visible

And my .xaml shows:

 <Grid>
    <Menu Height="26" HorizontalAlignment="Left" Margin="-1,0,0,0" Name="menu1" VerticalAlignment="Top" Width="504" Opacity="88">
    <MenuItem Header="_Menu"/>
    <MenuItem Header="_View"/>
    <MenuItem Header="_Edit"/>
    </Menu>
</Grid>

When I debug the program the "Menu" or any of the MenuItems does not show up on the Active Windows Form.

Any thoughts?

Answer 1

Add right after your window element <DockPanel Width="Auto" Height="Auto" LastChildFill="True">

And then add this attribute into your menu element: DockPanel.Dock="Top"

Answer 2

Make sure you explicitly save and re-compile your application after making XAML changes.

I've personally had a lot of instances where XAML changes simply did not show up when debugging an application. To be sure your changes are going through, you can clean the solution and rebuild.
