我是 WPF 的新手,我正在创建一个用户控件,如下所示:
<UserControl x:Class="WpfApplication3.MyUserControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
x:Name="MyUserControl2"
d:DesignHeight="300" d:DesignWidth="300" Background="Coral">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="20"/>
<RowDefinition Height="20"/>
<RowDefinition Height="20"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Button Content="a" Grid.Row="0"/>
<Button Content="b" Grid.Row="1"/>
<Button Content="c" Grid.Row="2"/>
<ContentPresenter Grid.Row="3"/>
</Grid>
当橙色区域是内容预设器时,这会产生以下布局:
在使用用户控件的主窗口中,我想将控件注入内容预设器
<Window x:Class="WpfApplication3.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication3"
Title="MainWindow" Height="350" Width="525">
<Grid>
<local:MyUserControl>
<local:MyUserControl.Content>
<Button Content="d"/>
</local:MyUserControl.Content>
</local:MyUserControl>
</Grid>
我希望得到以下布局:
但相反,整个用户控件被按钮 d 重叠。
我该如何做到这一点?
