我是WPF的新手。我想要一个正确的对齐菜单。但是当将horizontalalignment属性设置为right时,它不会填充整行的宽度。我使用horizontalcontentalignment作为拉伸,但它不起作用。这是我的代码:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="60" />
<RowDefinition Height="*" />
<RowDefinition />
</Grid.RowDefinitions>
<DockPanel Grid.Row="0" Grid.Column="0" HorizontalAlignment="Right">
<Menu DockPanel.Dock="Top" >
<MenuItem Header="_File"/>
<MenuItem Header="_Edit"/>
<MenuItem Header="_Help"/>
</Menu>
</DockPanel>
</Grid>
显示的内容如下:
-----------------------------
File edit help |
-----------------------------
但我想成为:
---------------------------------
Help edit file|
--------------------------------
如何获得菜单填充顶部并将其对齐设置为正确?

你可以这样做:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="60" />
<RowDefinition Height="*" />
<RowDefinition />
</Grid.RowDefinitions>
<Menu Grid.Row="0" Grid.Column="0" HorizontalAlignment="Stretch">
<Menu.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel HorizontalAlignment="Right" Orientation="Horizontal" VerticalAlignment="Top" />
</ItemsPanelTemplate>
</Menu.ItemsPanel>
<MenuItem Header="_File" />
<MenuItem Header="_Edit"/>
<MenuItem Header="_Help"/>
</Menu>
</Grid>
