Question

我是WPF的新手，我正在为大学制作一个带定制按钮的WPF项目。

 <Style x:Key="Button113" TargetType="{x:Type Button}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid>
                        <Path x:Name="path" Fill="#FF8E2424" Stretch="Fill" Opacity="0.0" Stroke="{x:Null}" Data="M575.33333,304.87333 C651.33333,305.20667 651.33365,305.20699 651.33365,305.20699 620.33383,380.13463 620.16716,380.46764 620.16716,380.46764 576.16698,380.30114 576.16698,380.30114 576.16698,380.30114 575.50031,305.04016 575.33333,304.87333 575.33333,304.87333 z"/>
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RecognizesAccessKey="True"/>
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Fill" TargetName="path" Value="DarkSlateBlue"/>
                            <Setter Property="Opacity" TargetName="path" Value="0.4"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

然后我使用样式

创建按钮

 <Button x:Name="button113" HorizontalAlignment="Right" Margin="0,0,16.25,27.416" Style="{DynamicResource Button113}" VerticalAlignment="Bottom" Width="78" Height="77.834" Content="" ToolTip="" ToolTipOpening="Button_ToolTipOpening" Click="form6_roomBtn_Click"/>

我在鼠标悬停时按钮改变颜色时遇到了一些麻烦，但不知怎的，我设法用触发器做了。

现在我想从我的c＃代码中更改按钮的背景属性，但没有任何反应。如何从我的代码访问路径的fill属性？（我尝试使用path.Fill但路径无法识别）。

谢谢

访问ControlTemplate中的项目变得令人头疼，尤其是如果您未定义模板的类。我建议尝试这样做：

<Style x:Key="Button113" TargetType="{x:Type Button}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid>
                        <Path x:Name="path" Fill="{TemplateBinding Background}" Stretch="Fill" Opacity="0.0" Stroke="{x:Null}" Data="M575.33333,304.87333 C651.33333,305.20667 651.33365,305.20699 651.33365,305.20699 620.33383,380.13463 620.16716,380.46764 620.16716,380.46764 576.16698,380.30114 576.16698,380.30114 576.16698,380.30114 575.50031,305.04016 575.33333,304.87333 575.33333,304.87333 z"/>
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RecognizesAccessKey="True"/>
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Fill" TargetName="path" Value="DarkSlateBlue"/>
                            <Setter Property="Opacity" TargetName="path" Value="0.4"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

这会将路径的填充绑定到Button的Background属性。现在，您可以随意更改Background属性，而无需从模板中获取内容。“/ p>

从代码中更改按钮路径的填充属性
