Quick WPF question - on Win 7 (and I assume Vista) in WPF, the default progress bar does a nice little glowing "whoosh"-y animation.
I'm showing progress of about 48 things on one screen, and it's a tad overwhelming to have all of these things whooshing on you - can you disable just these animations without affecting the rest of the default animations in the application?
I'd agree with Matthew's comment, but anyway, your answer is to apply a custom style without the animation. Here's the original style (via reflector), you can remove/tweak/whatever:
<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>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
