.NET MAUI CircularSlider Backtrack

Updated on Aug 11, 2026

The thumb runs along the backtrack of the CircularSlider. The backtrack represents all the values your end users can choose from.

Minimum and Maximum

You need to configure a Minimum value and a Maximum value for the CircularSlider. These values define the limits of the backtrack.

• Minimum (double)—Defines the minimum value of the slider.
• Maximum (double)—Defines the maximum value of the slider.

XAML

<telerik:RadCircularSlider Minimum="0"
                           Maximum="100"
                           Value="35" />

Backtrack Extent

By default, the backtrack is drawn between the Minimum and Maximum values. Through the BackTrackExtent property you can extend the backtrack at the edges beyond the minimum and the maximum values.

• BackTrackExtent (double)—Defines how many pixels beyond the minimum and the maximum values the backtrack extends.
