Removing gloss from progressbar?
提问by Duncan Palmer
So I was suggested to use WPF forms to make a custom UI for my applications. The first thing I wanted to try was to change the look of the progress bar. The only thing holding me back from it's new look atis the glossy effect over the top of it. I want the progrss bar to be made of mostly solid colours. Is there anyway to remove the glossy part of the progress bar?
所以有人建议我使用 WPF 表单为我的应用程序制作自定义 UI。我想尝试的第一件事是更改进度条的外观。唯一让我对它的新外观望而却步的是它顶部的光泽效果。我希望进度条主要由纯色制成。无论如何要删除进度条的光泽部分？

Nasreddine answers is very good but if you want something simpler you can use the following
Nasreddine 的答案非常好，但如果你想要更简单的东西，你可以使用以下内容
<Style TargetType="{x:Type ProgressBar}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ProgressBar">
<Border BorderBrush="#D9DCE1" BorderThickness="1" Background="#E8E8E8" CornerRadius="0" Padding="0">
<Grid x:Name="PART_Track">
<Rectangle x:Name="PART_Indicator" HorizontalAlignment="Left" Fill="#FF49A3E1" />
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
