【问题标题】:how to add effect for text box to style如何为文本框添加样式效果
【发布时间】:2011-07-06 15:45:27
【问题描述】:
我正在尝试为样式添加一种效果以重用它,但由于某种原因它不起作用...
<Style x:Key="NumericTextBoxStyle" TargetType="{x:Type TextBox}">
<Style.Resources>
<TextBox.Effect x:Key="EffectStyle">
<DropShadowEffect BlurRadius="56"
Direction="392"
Color="#FF872E2E"
RenderingBias="Quality"/>
</TextBox.Effect>
</Style.Resources>
<Setter Property="Height" Value="25"/>
<Setter Property="Width" Value="120"/>
<Setter Property="HorizontalAlignment" Value="Right"/>
<Setter Property="VerticalAlignment" Value="Top"/>
<Setter Property="TextAlignment" Value="Center"/>
</Style>
但是如何添加样式部分? (还有我如何声明效果?)
谢谢

【解决方案1】:
尝试将 Effect 添加为 Setter
<Style x:Key="NumericTextBoxStyle" TargetType="{x:Type TextBox}">
<Setter Property="Effect">
<Setter.Value>
<DropShadowEffect BlurRadius="56"
Direction="392"
Color="#FF872E2E"
RenderingBias="Quality"/>
</Setter.Value>
</Setter>
<Setter Property="Height" Value="25"/>
<Setter Property="Width" Value="120"/>
<Setter Property="HorizontalAlignment" Value="Right"/>
<Setter Property="VerticalAlignment" Value="Top"/>
<Setter Property="TextAlignment" Value="Center"/>
</Style>
或者,如果您想将效果作为样式中的资源,您可以这样做
<Style x:Key="NumericTextBoxStyle" TargetType="{x:Type TextBox}">
<Style.Resources>
<DropShadowEffect x:Key="dropShadowEffect"
BlurRadius="56"
Direction="392"
Color="#FF872E2E"
RenderingBias="Quality"/>
</Style.Resources>
<Setter Property="Effect" Value="{StaticResource dropShadowEffect}"/>
<!--...-->
</Style>
【解决方案2】:
您还可以将效果设为全局资源,以便与其他样式/控件一起使用:
<Grid>
<Grid.Resources>
<DropShadowEffect x:Key="dropShadowEffect" BlurRadius="56"
Direction="392"
Color="#FF872E2E"
RenderingBias="Quality"/>
<Style x:Key="NumericTextBoxStyle" TargetType="{x:Type TextBox}">
<Setter Property="Effect" Value="{StaticResource dropShadowEffect}" />
<Setter Property="Height" Value="25"/>
<Setter Property="Width" Value="120"/>
</Style>
</Grid.Resources>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
<RowDefinition />
</Grid.RowDefinitions>
<TextBox Style="{StaticResource NumericTextBoxStyle}" />
<TextBox Style="{StaticResource NumericTextBoxStyle}" Grid.Row="1" />
<ComboBox Effect="{StaticResource dropShadowEffect}" Grid.Row="2" />
</Grid>
