将样式应用于 WPF 中的所有派生类 [英] Applying a style to all derived classes in WPF

问题描述

我想对从 Control 派生的所有类应用一种样式.WPF可以做到这一点吗?以下示例不起作用.我希望标签、文本框和按钮的边距为 4.

I want to apply a style to all classes derived from Control. Is this possible with WPF? The following example does not work. I want the Label, TextBox and Button to have a Margin of 4.

<Window x:Class="WeatherInfo.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Wetterbericht" Height="300" Width="300">
    <Window.Resources>
        <Style TargetType="Control">
            <Setter Property="Margin" Value="4"/>
        </Style>
    </Window.Resources>
    <Grid>
        <StackPanel Margin="4" HorizontalAlignment="Left">            
            <Label>Zipcode</Label>
            <TextBox Name="Zipcode"></TextBox>
            <Button>get weather info</Button>
        </StackPanel>
    </Grid>
</Window>

推荐答案

这是一个解决方案:

<Window.Resources>
    <Style TargetType="Control" x:Key="BaseStyle">
        <Setter Property="Margin" Value="4"/>
    </Style>
    <Style BasedOn="{StaticResource BaseStyle}" TargetType="Button" />
    <Style BasedOn="{StaticResource BaseStyle}" TargetType="Label" />
    <Style BasedOn="{StaticResource BaseStyle}" TargetType="TextBox" />
</Window.Resources>
<Grid>
    <StackPanel Margin="4" HorizontalAlignment="Left">
        <Label>Zipcode</Label>
        <TextBox Name="Zipcode"></TextBox>
        <Button>get weather info</Button>
    </StackPanel>
</Grid>
