The RangeSlider has a Text property that shows up in the Properties window in design view but I don't see any way to show it. Some of the screenshot in the documentation show text above the slider bar, which identifies what the slider is for (for example, "Temperature").

Hi Keith A
After reviewing the above text, it seems
that the 'Text' property of the RangeSlider is not being used in accordance
with the documentation format. Instead, it is recommended to use the AutoLabel
control to display the text associated with the RangeSlider. please refer the
sample for your reference.
