You might use Extended WPF Toolkit which has a BusyIndicator control,

http://wpftoolkit.codeplex.com/wikipage?title=BusyIndicator

Samples are included in the download.

For your information, Microsoft introduces BusyIndicator in Silverlight first (but fails to ship one for WPF) as a replacement of progress bar.

you can do that in different scenarios.

  1. using triggers, (I'd prefer that)

    <ProgressBar Maximum="100" Margin="10,107,232,168" Value="0" Name="progr">
    <ProgressBar.Resources>
        <Style TargetType="{x:Type ProgressBar}">
            <Style.Triggers>
                <DataTrigger Binding="{Binding RelativeSource={RelativeSource Self}, Path=Value}" Value="100">
                    <Setter Property="Visibility" Value="Hidden"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </ProgressBar.Resources>
</ProgressBar>

  2. Using converters

    <Grid>
<Grid.Resources>
    <delWpf:VisibilityConverter x:Key="conv"/>
</Grid.Resources>
    <ProgressBar Name="prog2" Minimum="0" Maximum="100" 
       Value="{Binding CurrentIndex, UpdateSourceTrigger=PropertyChanged}" 
       Visibility="{Binding RelativeSource={RelativeSource Self}, Path=Value, Mode=OneWay, Converter={StaticResource conv}}" />
</Grid>

and converter

    public class VisibilityConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            return Math.Abs((double)value - 100) < 0.001 ? Visibility.Hidden : Visibility.Visible;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }
