So far it looks like the only way is to override the style, I was just wondering if there were a simpler solution:
<
telerik:RadSlider.AutoToolTipContentTemplate
>
<
DataTemplate
>
<
Grid
Width
=
"32"
Height
=
"44"
Background
=
"Transparent"
>
<
Path
Data
=
"M12,6C12,9.3 7.9,13.8 6,16C4.1,13.6 0,9.3 0,6C0,2.6 2.6,0 6,0C9.3,0 12,2.6 12,6z"
Fill
=
"{telerik:MaterialResource ResourceKey=PrimaryNormalBrush}"
Stretch
=
"Fill"
/>
<
TextBlock
x:Name
=
"PinText"
Text
=
"{Binding .,Converter={StaticResource NumericPrecisionConverter}, ConverterParameter=0}"
FontSize
=
"11"
Foreground
=
"{telerik:MaterialResource ResourceKey=MarkerInvertedBrush}"
Margin
=
"0 12 0 0"
HorizontalAlignment
=
"Center"
VerticalAlignment
=
"Top"
FontWeight
=
"Normal"
/>
</
Grid
>
</
DataTemplate
>
</
telerik:RadSlider.AutoToolTipContentTemplate
>
