我在我的应用程序中使用了一个不确定的进度条，我得到了一系列水平运行的块的坏动画。是不是有像Vista或Windows 7更好的风格？
答案 0 :(得分：17)
您的进度条的样式与您当前的Windows主题相对应。如果您在带有Aero主题的Windows 7上运行应用程序，则进度条将相应显示。
如果您希望它看起来始终一致（无论选择哪个窗口主题），您都需要为进度条定义自己的样式。
以下是Aero Normal Color主题的风格：

将此代码放入应用程序的Themes/Generic.xaml文件中，进度条将始终具有此样式。

这是另一个... IsInderminate模式非常简单的平面进度条 -
<ControlTemplate x:Key="CustomProgressBar" TargetType="ProgressBar" >
<Grid Name="TemplateRoot" SnapsToDevicePixels="True">
<Rectangle RadiusX="2" RadiusY="2" Fill="Transparent" />
<Border CornerRadius="0,0,0,0" Margin="1,1,1,1">
<Border.Background>
<SolidColorBrush Color="Transparent"/>
</Border.Background>
</Border>
<Border BorderThickness="0,0,0,0" BorderBrush="Transparent" Margin="1,1,1,1">
<Border.Background>
<SolidColorBrush Color="Transparent"/>
</Border.Background>
</Border>
<Rectangle Name="PART_Track" Margin="1,1,1,1" />
<Decorator Name="PART_Indicator" Margin="1,1,1,1" HorizontalAlignment="Left">
<Grid Name="Foreground">
<Rectangle Fill="Transparent" Name="Indicator" />
<Grid Name="Animation" ClipToBounds="True">

这是我使用Suneet的示例制作的自定义进度条，但IsIndeterminate动画在.NET 3.5中运行：
<Style x:Key="{x:Type ProgressBar}" TargetType="{x:Type ProgressBar}">
<Setter Property="Foreground" Value="#54bdcd"/>
<Setter Property="Background" Value="#000000"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">
<Grid Name="TemplateRoot" SnapsToDevicePixels="true">
<Rectangle Fill="{TemplateBinding Background}"/>
<Rectangle Name="PART_Track" Margin="0"/>
<Decorator x:Name="PART_Indicator" HorizontalAlignment="Left" Margin="0">
<Grid Name="Foreground">
<Rectangle Fill="{TemplateBinding Foreground}" Name="Indicator" />
<Grid Name="Animation" ClipToBounds="True">
<Border Name="PART_GlowRect" Margin="0,0,0,0" HorizontalAlignment="Left" Background="{TemplateBinding Foreground}"/>
</Grid>
<Grid Name="Overlay">
</Grid>
</Grid>
</Decorator>
<Border BorderThickness="{TemplateBinding BorderThickness}"
BorderBrush="{TemplateBinding BorderBrush}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsIndeterminate" Value="true">
<Setter TargetName="Indicator" Property="Fill" Value="Transparent" />
<Setter TargetName="PART_GlowRect" Property="Width" Value="100" />
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation
Storyboard.TargetName="PART_GlowRect"
Storyboard.TargetProperty="Margin"
From="-50,0,0,0" To="400,0,0,0" Duration="0:0:2"
AutoReverse="True" RepeatBehavior="Forever" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
这有点像黑客，因为我通过更改其marginleft值来回移动不确定的条，但在我的情况下它是可以承受的，因为我的进度条是固定的宽度。
如果您有更好的主意，请随时更改故事板部分。 This page给了我很多帮助。

这是支持普通和中间模式的另一个：
<Style TargetType="{x:Type ProgressBar}">
<Setter Property="Foreground" Value="#1BA1E2"/>
<Setter Property="Background" Value="#EEEEEE"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">
<Grid Name="TemplateRoot" SnapsToDevicePixels="true">
<Rectangle Fill="{TemplateBinding Background}"/>
<Rectangle Name="PART_Track" Margin="0"/>
<Decorator x:Name="PART_Indicator" HorizontalAlignment="Left" Margin="0">
<Grid Name="Foreground">
<Rectangle Fill="{TemplateBinding Foreground}" Name="Indicator" />
<Grid x:Name="Animation" ClipToBounds="true" Visibility="Hidden">
<Rectangle Fill="{TemplateBinding Background}" Name="HiderPre" Margin="0,0,50,0">
<Rectangle.RenderTransform>
<ScaleTransform x:Name="HiderPreTransform" ScaleX="0"/>
</Rectangle.RenderTransform>
</Rectangle>
<Rectangle Fill="{TemplateBinding Background}" Name="HiderPost" RenderTransformOrigin="1, 0" Margin="50,0,0,0">
<Rectangle.RenderTransform>
<ScaleTransform x:Name="HiderPostTransform" ScaleX="1" />
</Rectangle.RenderTransform>
</Rectangle>
</Grid>
<Grid Name="Overlay">
</Grid>
</Grid>
</Decorator>
<Border BorderThickness="{TemplateBinding BorderThickness}"
BorderBrush="{TemplateBinding BorderBrush}"/>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsIndeterminate" Value="true">
<Setter TargetName="Animation" Property="Visibility" Value="Visible" />
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard RepeatBehavior="Forever">
<DoubleAnimation
Storyboard.TargetName="HiderPreTransform"

<DoubleAnimation

我能找到的最简单的方法主要基于 https://stackoverflow.com/a/19737148/3195477，但更加简化。
这会产生一个简单的平面外观：
<ProgressBar>
<ProgressBar.Template>
<ControlTemplate TargetType="ProgressBar">
<Border
BorderBrush="Black"
BorderThickness="1"
Background="LightGray"
>
<Grid x:Name="PART_Track">
<Rectangle
x:Name="PART_Indicator"
HorizontalAlignment="Left"
Fill="Blue"
/>
</Grid>
</Border>
</ControlTemplate>
</ProgressBar.Template>
</ProgressBar>
“诀窍”是用非常简单的替代品最低限度地替换命名部分。您不一定需要复杂的渐变等来改进默认外观，尽管这是一个见仁见智的问题。
