Slider.Minimum property negative value issue

Question

Probably I've got another unsolvable problem. In Silverlight XAML, I am unable to set by Style negative value for Slider.Minimum property. I mean, it is possible, but the results are unexpected. In WPF this does work normally.

<StackPanel Width="200" Orientation="Vertical">
    <StackPanel.Resources>
        <Style TargetType="Slider" x:Key="style">
            <Setter Property="Minimum" Value="-10" />
            <Setter Property="Maximum" Value="10" />
            <Setter Property="Value" Value="0" />
        </Style>
    </StackPanel.Resources>
    <!-- Here it is not working -->
    <Slider Style="{StaticResource style}"/>
    <!-- Here it works as expected, as it is not styled -->
    <Slider Minimum="-10" Maximum="10" Value="0" />
</StackPanel>

The result is like this:

But obviously both thumbs should be in the same position (in the middle of Slider).

In fact, it look's like the Minimum value (-10) is accepted, but then Maximum value becomes 0, and that is why the first slider has a thumb aligned to a right side (Value is 0 and Maximum is also 0).

Answer 1

The problem is the HorizontalTemplate of the Slider. If you change the Orientation of the Slider to Vertical then the values defined in your style get applied as expected.

Update: The Solution is to set the Orientation also in the style. Then it works as expected.

<Style TargetType="Slider" x:Key="style">
  <Setter Property="Minimum"
          Value="-10" />
  <Setter Property="Maximum"
          Value="10" />
  <Setter Property="Value"
          Value="0" />
  <Setter Property="Orientation"
          Value="Horizontal" />
 </Style>
