我有一个自定义UserControl
,我尝试将其添加到另一个UserControl
:
<UserControl x:Class="MyProject.Screens.Test"
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"
xmlns:local="clr-namespace:MyProject.Screens"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<Grid>
<Button Style="{StaticResource TestStyle}"/>
</Grid>
<UserControl.Resources>
<Style x:Key="TestStyle" TargetType="{x:Type Button}">
<Setter Property="Padding" Value="1"/>
</Style>
</UserControl.Resources>
它在设计窗口中看起来不错,并且项目编译良好。但是,如果我尝试将此UserControl
添加到另一个UserControl
:
<UserControl x:Class="MyProject.Screens.MainScreen"
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"
xmlns:local="clr-namespace:MyProject.Screens"
mc:Ignorable="d"
d:DesignHeight="1080" d:DesignWidth="1920">
<Grid>
<local:Test/>
</Grid>
</UserControl>
我收到一个错误:
找不到资源"测试样式">
在MainScreen
.我做错了什么?
将资源声明放在 Content 之前:
<UserControl ...>
<UserControl.Resources>
<Style x:Key="TestStyle" TargetType="{x:Type Button}">
<Setter Property="Padding" Value="1"/>
</Style>
</UserControl.Resources>
<Grid>
<Button Style="{StaticResource TestStyle}"/>
</Grid>
</UserControl>
