Resources/Shared.xaml 中的样式定义(更新):
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:system="clr-namespace:System;assembly=mscorlib">
<system:Double x:Key="fullHeight" >26</system:Double>
<system:Double x:Key="halfHeight" >16</system:Double>
<Thickness x:Key="m">10</Thickness>
<Style TargetType="Button">
<Setter Property="FontSize" Value="{StaticResource fullHeight}"/>
<Setter Property="Margin" Value="{StaticResource m}"/>
<Setter Property="Padding" Value="10"/>
</Style>
<Style TargetType="Label">
<Setter Property="FontSize" Value="{StaticResource fullHeight}"/>
<Setter Property="Margin" Value="{StaticResource m}"/>
<Setter Property="VerticalAlignment" Value="Center"/>
</Style>
<Style TargetType="TextBlock">
<Setter Property="FontSize" Value="{StaticResource fullHeight}"/>
<Setter Property="Margin" Value="{StaticResource m}"/>
</Style>
<Style TargetType="TextBox">
<Setter Property="FontSize" Value="{StaticResource fullHeight}"/>
<Setter Property="Margin" Value="{StaticResource m}"/>
<Setter Property="Padding" Value="10"/>
</Style>
<Style TargetType="PasswordBox">
<Setter Property="FontSize" Value="{StaticResource fullHeight}"/>
<Setter Property="Margin" Value="{StaticResource m}"/>
<Setter Property="Padding" Value="10"/>
</Style>
<Style TargetType="ListView">
<Setter Property="FontSize" Value="{StaticResource fullHeight}"/>
<Setter Property="Margin" Value="{StaticResource m}"/>
<Setter Property="Padding" Value="10"/>
</Style>
<Style TargetType="ComboBox">
<Setter Property="Margin" Value="{StaticResource m}"/>
</Style>
</ResourceDictionary>
窗户:
<Window.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="../Resources/Shared.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Window.Resources>
用户控制:
<StackPanel Orientation="Horizontal">
<Label Content="Text" Background="AliceBlue"/>
<Label Content="{Binding DecimalValue, FallbackValue=50}" Background="Aquamarine"/>
</StackPanel>
模型:
private decimal _DecimalValue;
public decimal DecimalValue
{
get { return _DecimalValue; }
set
{
if (_DecimalValue != value)
{
_DecimalValue = value;
NotifyOfPropertyChange();
}
}
}
如果有什么不同,我正在使用 Caliburn.Micro。
结果:
为什么?
更新:经过一番窥探,结果发现第一个标签的内部 TextBlock 的边距为 0,值源为默认值,第二个为 10 和样式。
更新 2:在阅读了这个问题之后,事实证明定义的TextBlock
样式不应该应用于TextBlocks
inside Labels
。所以似乎绑定的存在以Label
某种方式改变了这一点。
