Slider Control

The Slider control allows users to select a value from a range of numbers by moving a slider thumb along a track.

Overview

Sliders are ideal for scenarios where users need to adjust a setting that falls within a defined range, such as volume, brightness, or zoom levels. They provide a visual and intuitive way to make these adjustments.

XAML Definition

You can define a Slider in XAML like this:

<Slider Minimum="0" Maximum="100" Value="50" />
        

Key Properties

Common Scenarios & Best Practices

• Volume/Brightness: Use sliders for adjusting continuous values like audio volume or screen brightness.
• Zoom Level: Suitable for controlling zoom factors in image viewers or maps.
• Range Selection: Can be used to select a value within a specific range, like a price filter.
• Visual Feedback: Always provide clear visual feedback for the current value, either by displaying it next to the slider or through other UI elements.
• Large Ranges: For very large ranges, consider using a TextBox or NumberBox in conjunction with the slider, or providing a way to input values directly.
• Accessibility: Ensure the slider is navigable and usable with keyboard controls. Use appropriate ARIA attributes if implementing custom sliders.
