    </Grid.RowDefinitions>
    <StackPanel Grid.Row="" VerticalAlignment="Center" HorizontalAlignment="Center">
        <ProgressBar Name="pb1" Height="" Width="" Foreground="LightBlue" IsIndeterminate="True"></ProgressBar>
    </StackPanel>
    <StackPanel Grid.Row="" VerticalAlignment="Center" HorizontalAlignment="Center">

        <Button Name="btn" MaxWidth="" Margin="" Click="BTN_Click">Start</Button>
    </StackPanel>
</Grid>

private void BTN_Click(object sender, RoutedEventArgs e)
{
    Duration duration = new Duration(TimeSpan.FromSeconds());
    DoubleAnimation doubleAnimation = new DoubleAnimation(, duration);
    pb2.BeginAnimation(ProgressBar.ValueProperty, doubleAnimation);
}

很常见的滑块，控件的外观上显示一系例刻度值，并存在一个可以被拖动的滑块，用户可以通过拖动滑块来控制控件的值

<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition />
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
    <Rectangle Grid.Column="" x:Name="rect" Fill="Black"></Rectangle>
    <StackPanel Grid.Column="">
        <StackPanel Orientation="Horizontal" Margin="10,2,5,2" >
            <TextBlock Text="R" Margin="5,1,1,1" VerticalAlignment="Center"></TextBlock>
            <Slider Name="RSlider" Margin="" Minimum="" Maximum="" TickFrequency="" Ticks="0,50,100,150,200,250"
                    TickPlacement="BottomRight" IsSnapToTickEnabled="False" ValueChanged="RSlider_ValueChanged" MinWidth=""></Slider>
        </StackPanel>
        <StackPanel Orientation="Horizontal" Margin="10,2,5,2" >
            <TextBlock Text="G" Margin="5,1,1,1" VerticalAlignment="Center"></TextBlock>

        </StackPanel>
    </StackPanel>
</Grid>

private void RSlider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
        {
            Update();
        }

        private void BSlider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)

        private void GSlider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
        {
            Update();
        }

        private void Update()
        {
            Color color = Color.FromRgb(Convert.ToByte(RSlider.Value), Convert.ToByte(BSlider.Value), Convert.ToByte(GSlider.Value));
            rect.Fill = new SolidColorBrush(color);
        }
