Question

How I can get step (0.5) in slider control in WP7?

It can change values like 0.5-1.0-1.5-2.0…

Answer 1

Set the SmallChange and LargeChange properties to 0.5. Like this:

<Slider x:Name="Slider" SmallChange="0.5" LargeChange="0.5" />

In addition, you can handle the ValueChanged event like so:

private void Slider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
    Slider.Value = Math.Round(e.NewValue * 2) /2;
}
