我有一个被圆角边框包围的文本框。它们都具有相同的背景颜色,使它们显示为单个数据输入框。当用户单击文本框时,文本框的背景和边框会更改颜色。样式在我的MainWindow中时,我有这个工作。但是,我试图将我的所有样式从MainWindow中的XAML抽象为中央资源字典。这样做,我发现改变边框背景颜色的DataTrigger不起作用,因为ElementName不再在范围内(至少我认为这是问题)。我试图通过在测试项目/解决方案中执行此操作来简化操作,但似乎无法找到使数据触发器工作的方法。我只有两个XAML文件。一个是我的MainWindow,另一个是我的资源词典。 MainWindow XAML如下:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<ResourceDictionary Source="/MainSkins.xaml"/>
</Window.Resources>
<Grid HorizontalAlignment="Left" Width="307" Margin="83,0,0,0">
<Border Style="{StaticResource AnimatedInputTextBoxBorder}"
Margin="10,76,10,151">
<TextBox Name="txtTransitRoutingNumber" Style="{StaticResource
AnimatedInputTextBox}"
HorizontalAlignment="Left" Height="73" Margin="9,9,0,0"
TextWrapping="Wrap" Text=""
VerticalAlignment="Top"
Width="267"/>
</Border>
</Grid>
</Window>
这是我的资源字典,正如我上面提到的那样,它与MainWindow.xaml完全不同:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:WpfApplication1">
<Style x:Key="AnimatedInputTextBoxBorder" TargetType="{x:Type Border}">
<Setter Property="Background" Value="#DADADA"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Padding" Value="5"/>
<Setter Property="CornerRadius" Value="15"/>
<Setter Property="BorderBrush" Value="#DADADA"/>
<Style.Triggers>
<!--THIS DATA TRIGGER IS NOT WORKING-->
<DataTrigger Binding="{Binding Path=IsFocused}" Value="true">
<Setter Property="Background" Value="#C2E4F6" />
<Setter Property="BorderBrush" Value="#C2E4F6"/>
</DataTrigger>
</Style.Triggers>
</Style>
<Style x:Key="AnimatedInputTextBox" TargetType="{x:Type TextBox}">
<Setter Property="Background" Value="#DADADA"/>
<Setter Property="Foreground" Value="#000000" />
<Setter Property="BorderThickness" Value="0"/>
<Style.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="Background" Value="#C2E4F6"/>
</Trigger>
</Style.Triggers>
</Style>
</ResourceDictionary>
非常感谢任何帮助,因为在XAML方面我是一个全新的人。

感谢Chris W.,我找到了一个效果很好的解决方法。这是解决方案:
<!--This style defines the animated input TextBoxes with rounded corners-->
<Style x:Key="AnimatedTextBoxStyle" TargetType="{x:Type TextBox}">
<Setter Property="Background" Value="#DADADA" />
<Setter Property="BorderBrush" Value="#DADADA" />
<Setter Property="BorderThickness" Value="1" />
<Setter Property="FontSize" Value="14" />
<Setter Property="TextAlignment" Value="Left"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBoxBase}">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="5">
<ScrollViewer x:Name="PART_ContentHost" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsFocused" Value="True">
<Setter Property="Foreground" Value="Black" />
<Setter Property="Background" Value="#C2E4F6" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
