c# - WPF 中按钮启用和禁用状态的不同图像

Question

我想在下面的代码中根据按钮的状态更改按钮的图像，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。

您可以像这样使用带有触发器的样式:

<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>
