WPF/Windows 7 : Disable Default Progress Bar Glow Animation

Question

WPF的快速问题-在WPF中，在Win 7(我假设是Vista)上，默认进度栏会显示出漂亮的发光“whoosh” -y动画。

我正在一个屏幕上显示大约48件事的进度，将所有这些事情都搞砸了实在是有点不知所措-您可以禁用这些动画而不影响应用程序中其余的默认动画吗？

我同意Matthew的评论，但是无论如何，您的答案是在不使用动画的情况下应用自定义样式。这是原始样式(通过反射器)，您可以删除/调整/任何内容:

<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">

    </Setter>

和转换器类:

public class ProgressBarBrushConverter : IMultiValueConverter
{
// Methods

    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;
    }

    if (flag)
    {

        double num9 = -num8 * num7;

        }
        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;
    }
    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;
