How to disable slider's tooltip?

Question

Bump!

I have a slider control which I'd like to work in a non-linear way. On value changes, I'm calculating the actual value, which is autoupdating another display field showing it. The slider's tooltip is in the way here. How do I disable it? It's nowhere in the slider style.

Answer 1

I just found out that WPF had a property called AutoTooltipPlacement, that allowed to disable this. Is there anything similar in WinRT?

Answer 2

Nevermind, there's actually a properly called ThumbToolTipValueConverter, to which you can a value converter to. In this case, I don't need to hide the tooltip. I'm now remapping the tooltip scale to the respective values it's supposed to represent.

public class TooltipConverter : IValueConverter
{
	Func<double, double> _ranger;

	public object Convert(object value, Type type, object parameter, string language)
	{
		double d = (double)value;
		return _ranger(d);
	}

	public object ConvertBack(object value, Type type, object parameter, string language)
	{
		throw new NotSupportedException();
	}

	public TooltipConverter(Func<double, double> ranger)
	{
		_ranger = ranger;
	}
}


// Magic
someSlider.ThumbToolTipValueConverter = new TooltipConverter(f => f * 2);

That said, apparently I was blind, because finding that value converter property, there's actually an IsThumbToolTipEnabled property that lets you disable it.

Set Slider.IsThumbToolTipEnabled="False" if you need to hide the Slider Thumb's ToolTip, or use Slider.ThumbToolTipValueConverter to customize what it displays.
