wpf - 更改按钮图像问题

Question

我在 WPF 中工作，我正在尝试更改按钮的图像，我创建了一些触发器和 setter ，但它不起作用。

这是我的 XAML 代码:

<Button BorderThickness="0" Height="23" HorizontalAlignment="Left" Margin="59,6,0,0" Name="topButton" Width="26"  VerticalAlignment="Top"  
            Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}" IsEnabled="False" >
        <StackPanel>
            <Image>
                <Image.Style>
                    <Style TargetType="Image">
                        <Style.Triggers>
                            <DataTrigger Binding="{Binding ElementName=topButton, Path=Button.IsEnabled}" Value="True">
                                <Setter Property="Image.Source" Value="Images/MoveFirst_Enabled.bmp" />
                            </DataTrigger>
                            <DataTrigger Binding="{Binding ElementName=topButton, Path=Button.IsEnabled}" Value="False">
                                <Setter Property="Image.Source" Value="Images/MoveFirst_Disabled.bmp" />
                            </DataTrigger>
                        </Style.Triggers>
                    </Style>
                </Image.Style>
            </Image>
        </StackPanel>
    </Button>

我无法意识到我做错了什么。希望您能够帮助我。先感谢您。

删除 Button.对于Path .所以而不是

Path=Button.IsEnabled

你应该有

Path=IsEnabled

例子

<Button BorderThickness="0" Height="23" HorizontalAlignment="Left" Margin="59,6,0,0" Name="topButton" Width="26"  VerticalAlignment="Top"               Style="{StaticResource {x:Static ToolBar.ButtonStyleKey}}" IsEnabled="False">
    <StackPanel>
        <Image>
            <Image.Style>
                <Style TargetType="Image">
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding ElementName=topButton, Path=IsEnabled}" Value="True">
                            <Setter Property="Source" Value="Images/MoveFirst_Enabled.bmp" />
                        </DataTrigger>
                        <DataTrigger Binding="{Binding ElementName=topButton, Path=IsEnabled}" Value="False">
                            <Setter Property="Source" Value="Images/MoveFirst_Disabled.bmp" />
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </Image.Style>
        </Image>
    </StackPanel>
</Button>
