WPF自定义进度条裁剪

我创建了一个自定义进度条，如下所示：

<!-- Custom progress bar -->
    <Style
        x:Key="CopyProgressBar"
        TargetType="ProgressBar">
        <Setter
            Property="Template">
            <Setter.Value>
                <ControlTemplate
                    TargetType="ProgressBar">
                    <Grid>
                        <Border
                            x:Name="PART_Track"
                            CornerRadius="5"
                            BorderBrush="#BBC6C4"
                            BorderThickness="2" />
                        <Rectangle
                            x:Name="PART_Indicator"
                            Fill="#A5B2B0"
                            RadiusX="5"
                            RadiusY="5"
                            Margin="3"
                            HorizontalAlignment="Left" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

它的使用方式如下：

<ProgressBar
            x:Name="copyProgress"
            Height="13"
            Width="279"
            Canvas.Left="158"
            Canvas.Top="103"
            Minimum="0"
            Maximum="100"
            Style="{StaticResource CopyProgressBar}" />

它工作得很好，但是当进度已满时，填充栏的右侧会被剪掉，这会删除我想要的舍入样式。我摆弄了填充、边距、最大宽度等，但我找不到防止剪切的方法。

I've created a custom progress bar as follows:

<!-- Custom progress bar -->
    <Style
        x:Key="CopyProgressBar"
        TargetType="ProgressBar">
        <Setter
            Property="Template">
            <Setter.Value>
                <ControlTemplate
                    TargetType="ProgressBar">
                    <Grid>
                        <Border
                            x:Name="PART_Track"
                            CornerRadius="5"
                            BorderBrush="#BBC6C4"
                            BorderThickness="2" />
                        <Rectangle
                            x:Name="PART_Indicator"
                            Fill="#A5B2B0"
                            RadiusX="5"
                            RadiusY="5"
                            Margin="3"
                            HorizontalAlignment="Left" />
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

Here's how it is used:

<ProgressBar
            x:Name="copyProgress"
            Height="13"
            Width="279"
            Canvas.Left="158"
            Canvas.Top="103"
            Minimum="0"
            Maximum="100"
            Style="{StaticResource CopyProgressBar}" />

It works quite well, but when the progress is full, the right side of the fill bar is clipped, which removes the rounding styling I'm going for. I've fiddled with padding, margins, max width, etc, but I can't find a way to prevent the clipping.

这是一个有趣的答案。我最终确定是导致问题的边距。进度条根据 PART_Track 的宽度设置 PART_Indicator 的宽度，而不考虑设置的边距或填充。以下样式将为您带来所需的行为。

<Style x:Key="CopyProgressBar" TargetType="ProgressBar">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ProgressBar">                  
                <Border BorderBrush="#BBC6C4" BorderThickness="1" CornerRadius="5" Padding="1">
                    <Grid x:Name="PART_Track" >
                        <Rectangle x:Name="PART_Indicator" HorizontalAlignment="Left" Fill="#A5B2B0" RadiusX="5" RadiusY="5"/>
                    </Grid>                  
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

This was an interesting one to answer. I finally got it nailed down to being the margin that was causing the problem. The progress bar sets the width of PART_Indicator based on the width of PART_Track regardless of the margin or paddings that are set. The following style will get you the desired behaviour.

<Style x:Key="CopyProgressBar" TargetType="ProgressBar">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ProgressBar">                  
                <Border BorderBrush="#BBC6C4" BorderThickness="1" CornerRadius="5" Padding="1">
                    <Grid x:Name="PART_Track" >
                        <Rectangle x:Name="PART_Indicator" HorizontalAlignment="Left" Fill="#A5B2B0" RadiusX="5" RadiusY="5"/>
                    </Grid>                  
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
