How to style a fancy vertical ProgressBar correctly?

Answer 1

Here's one alternative:

<Border BorderBrush="Black" BorderThickness="2" CornerRadius="3" Padding="3">
    <Grid Width="20" Height="100">
        <Grid Height="{Binding ProgressValue}" VerticalAlignment="Bottom">
            <Grid Height="100" VerticalAlignment="Bottom">
                <Grid.Background>
                    <LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
                        <GradientStop Color="Yellow" Offset="0.0" />
                        <GradientStop Color="Red" Offset="0.25" />
                        <GradientStop Color="Blue" Offset="0.75" />
                        <GradientStop Color="LimeGreen" Offset="1.0" />
                    </LinearGradientBrush>
                </Grid.Background>
            </Grid>
        </Grid>
    </Grid>
</Border>

Note the third line from the top, that is where you bind your progress value.

Write a selfhump function and have it recurse until you get the correct result.
