我正在更改Button的ControlTemplate并且我成功地能够更改视觉外观,但是当我尝试在ControlTemplate内部更改IsMouseOver触发器上的按钮内容时,它不起作用。以下是我的xaml:
<Window x:Class="WpfApplication1.Window2"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window2" Height="300" Width="300">
<Window.Resources>
<ControlTemplate x:Key="ngButton" TargetType="Button">
<Grid>
<Border Name="templateBorder" BorderThickness="2" Background="Blue" />
<Ellipse Name="el2" Margin="10,10,10,10" Fill="Magenta" />
<ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" Content="{TemplateBinding Content}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter TargetName="templateBorder" Property="Background" Value="DarkRed" />
<Setter TargetName="el2" Property="Fill" Value="Green" />
<Setter Property="Content">
<Setter.Value>
<TextBlock Text="Mouse is over" />
</Setter.Value>
</Setter>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter TargetName="templateBorder" Property="Background" Value="LightBlue" />
<Setter TargetName="templateBorder" Property="BorderBrush" Value="DarkKhaki" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Window.Resources>
<Grid>
<Button Content="Hello World" Template="{StaticResource ngButton}" Name="ngButtonHello" Height="200" Width="200"/>
</Grid>
感谢您的帮助。

请阅读Dependency Property Value Precedence:本地值(&#34; Hello World&#34;在您的示例中)始终优先于触发器设置的值。
在样式中设置原始内容属性,或使用本地值属性中的转换器将IsMouseOver
转换为特定字符串。
