我想根据按钮的状态更改下面代码中按钮的图像，即使用不同的图像来启用和禁用状态。
<Button CommandParameter="Open" >
<StackPanel Orientation="Horizontal" >
<Image Source="../icons/big/open.png" Width="20" Height="20"></Image>
</StackPanel>
</Button>
谢谢。
您可以使用带有触发器的样式，如下所示：
<Style TargetType="{x:Type Button}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<StackPanel Orientation="Horizontal" >
<Image Name="PART_Image" Source="path to normal image" />
</StackPanel>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Source" Value="path to mouse over image" TargetName="PART_Image"/>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Source" Value="path to pressed image" TargetName="PART_Image"/>
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Source" Value="path to disabled image" TargetName="PART_Image"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
