快速WPF的问题 - 在Win 7（和我假设Vista中）在WPF中，默认的进度条做一个可爱的小彤彤“嗖” -y动画。
我一分屏显示的约48事情的进展，这是压倒一点点把所有的这些东西嘶嘶的你 - 你可以在不影响应用程序的默认动画的其余部分仅禁用这些动画？
Answer 1:
我与马修的评论表示赞同，但无论如何，你的答案是应用自定义样式而不动画。 这里的原始风貌（通过反射器），你可以删除/调整/什么：
<Style x:Key="{x:Type ProgressBar}" TargetType="{x:Type ProgressBar}">
<Style.Triggers>
<Trigger Property="Orientation" Value="Vertical">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">
<Border Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" CornerRadius="3" SnapsToDevicePixels="true">
<Border BorderThickness="1,1,1,0" BorderBrush="#BEBEBE" CornerRadius="2">
<Border BorderThickness="1" BorderBrush="#EFEFEF" CornerRadius="1">
<DockPanel Name="PART_Track" Margin="0,0,0,1" LastChildFill="false">
<Decorator Name="PART_Indicator" Dock="Bottom">
<Rectangle LayoutTransform="{RotateTransform Angle=-90}">
<Rectangle.Fill>
<MultiBinding Converter="{theme:ProgressBarBrushConverter}">
<Binding Path="Foreground" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="IsIndeterminate" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="ActualHeight" ElementName="PART_Indicator" />
<Binding Path="ActualWidth" ElementName="PART_Indicator" />
<Binding Path="ActualHeight" ElementName="PART_Track" />
</MultiBinding>
</Rectangle.Fill>
</Rectangle>
</Decorator>
</DockPanel>
</Border>
</Border>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Trigger>
</Style.Triggers>
<Setter Property="Foreground" Value="{StaticResource [0] Ñ}" />
<Setter Property="Background" Value="{DynamicResource {x:Static WindowBrush}}" />
<Setter Property="BorderBrush" Value="#686868" />
<Setter Property="BorderThickness" Value="1" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ProgressBar}">
<Border Background="{TemplateBinding Background}" BorderThickness="{TemplateBinding BorderThickness}" BorderBrush="{TemplateBinding BorderBrush}" CornerRadius="3" SnapsToDevicePixels="true">
<Border BorderThickness="1,1,1,0" BorderBrush="#BEBEBE" CornerRadius="2">
<Border BorderThickness="1" BorderBrush="#EFEFEF" CornerRadius="1">
<DockPanel Name="PART_Track" Margin="1,0,0,1" LastChildFill="false">
<Rectangle Name="PART_Indicator">
<Rectangle.Fill>
<MultiBinding Converter="{theme:ProgressBarBrushConverter}">
<Binding Path="Foreground" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="IsIndeterminate" RelativeSource="{RelativeSource TemplatedParent}" />
<Binding Path="ActualWidth" ElementName="PART_Indicator" />
<Binding Path="ActualHeight" ElementName="PART_Indicator" />
<Binding Path="ActualWidth" ElementName="PART_Track" />
</MultiBinding>
</Rectangle.Fill>
</Rectangle>
</DockPanel>
</Border>
</Border>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
和转换器类：
public class ProgressBarBrushConverter : IMultiValueConverter
{
// Methods
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
Type type = typeof(double);
if (((((values == null) || (values.Length != 5)) || ((values[0] == null) || (values[1] == null))) || (((values[2] == null) || (values[3] == null)) || ((values[4] == null) || !typeof(Brush).IsAssignableFrom(values[0].GetType())))) || ((!typeof(bool).IsAssignableFrom(values[1].GetType()) || !type.IsAssignableFrom(values[2].GetType())) || (!type.IsAssignableFrom(values[3].GetType()) || !type.IsAssignableFrom(values[4].GetType()))))
{
return null;
}
Brush brush = (Brush) values[0];
bool flag = (bool) values[1];
double d = (double) values[2];
double num2 = (double) values[3];
double num3 = (double) values[4];
if ((((d <= 0.0) || double.IsInfinity(d)) || (double.IsNaN(d) || (num2 <= 0.0))) || (double.IsInfinity(num2) || double.IsNaN(num2)))
{
return null;
}
DrawingBrush brush2 = new DrawingBrush();
brush2.Viewport = brush2.Viewbox = new Rect(0.0, 0.0, d, num2);
brush2.ViewportUnits = brush2.ViewboxUnits = BrushMappingMode.Absolute;
brush2.TileMode = TileMode.None;
brush2.Stretch = Stretch.None;
DrawingGroup group = new DrawingGroup();
DrawingContext context = group.Open();
double x = 0.0;
double width = 6.0;
double num6 = 2.0;
double num7 = width + num6;
if (flag)
{
int num8 = (int) Math.Ceiling((double) (d / num7));
double num9 = -num8 * num7;
double num10 = d * 0.3;
brush2.Viewport = brush2.Viewbox = new Rect(num9, 0.0, num10 - num9, num2);
TranslateTransform transform = new TranslateTransform();
double num11 = num8 * 100;
DoubleAnimationUsingKeyFrames animation = new DoubleAnimationUsingKeyFrames();
animation.Duration = new Duration(TimeSpan.FromMilliseconds(num11));
animation.RepeatBehavior = RepeatBehavior.Forever;
for (int i = 1; i <= num8; i++)
{
double num13 = i * num7;
animation.KeyFrames.Add(new DiscreteDoubleKeyFrame(num13, KeyTime.Uniform));
}
transform.BeginAnimation(TranslateTransform.XProperty, animation);
brush2.Transform = transform;
while ((x + width) < num10)
{
context.DrawRectangle(brush, null, new Rect(num9 + x, 0.0, width, num2));
x += num7;
}
d = num10;
x = 0.0;
}
while ((x + width) < d)
{
context.DrawRectangle(brush, null, new Rect(x, 0.0, width, num2));
x += num7;
}
double num14 = d - x;
if ((!flag && (num14 > 0.0)) && (Math.Abs((double) (d - num3)) < 1E-05))
{
context.DrawRectangle(brush, null, new Rect(x, 0.0, num14, num2));
}
context.Close();
brush2.Drawing = group;
return brush2;
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
return null;
}
}
Answer 2:
罗伯特的回答是稳健的。 这里是一个黑客（因为它依赖于做辉光，这是一个实现细节并在后续的版本可以改变元件的内部名称）：
void SetGlowVisibility(ProgressBar progressBar, Visibility visibility) {
var glow = progressBar.Template.FindName("PART_GlowRect", progressBar) as FrameworkElement;
if (glow != null) glow.Visibility = visibility;
}
如果怎样一个进度条来实现的变化，这个技巧可能会停止工作。
在另一方面，它完全替代了XAML和风格的解决方案可以锁定和固定的颜色，边框等，并有可能被添加到进度在未来的新版本禁止的行为...
Answer 3:
简单的，非动画的进度条可以写成两个填充的矩形网格：左边的人会被填充，比如，用绿色，右边一个灰色的。
该网格将有两个列定义。
改变两者的宽度会使进度变化的影响。
Answer 4:
您也可以一起禁用在Win7这个效果。
桌面上的我的电脑图标上点击右键，选择属性（或按Windows键+暂停/ Break键），单击高级系统设置在左侧窗格中的链接（您也可以在运行中输入SYSDM.CPL打开或开始菜单搜索框，然后按Enter）。 现在点击在性能部分的设置按钮：
取消“动画窗口内控件和元素”，它应该是第一选择。
Answer 5:
不是我的范围，但这个答案可能是太有关： 在Vista的Aero禁用进度条动画
Answer 6:
创建一个快捷方式到您正在使用的应用程序，右键单击该快捷方式并选择属性。 现在，在兼容性选项卡中单击“禁用视觉主题”复选框。
