Syncfusion maui toolkit bottom sheet

.NET MAUI Bottom Sheet (SfBottomSheet)

Overview

The Bottom Sheet is a user interface component that slides up from the bottom of the screen, allowing users to interact with additional information or actions without navigating away from the main screen. The Syncfusion SfBottomSheet control provides comprehensive state management, content configuration, gesture support, and extensive customization options for .NET MAUI applications.

Key Features:

• Multiple states: FullExpanded, HalfExpanded, Collapsed, Hidden
• Flexible content configuration with data binding support
• Touch gestures: swipe to expand/collapse
• Extensive customization: colors, dimensions, corner radius, padding, grabber styling
• Event handling and state change notifications
• Modal and non-modal display modes
• Programmatic control via IsOpen property and Show/Close methods

When to Use This Skill

Use this skill when you need to:

• Display supplementary content without full page navigation (product details, information panels, settings)
• Create data-driven interactions that bind list selections to detailed content views
• Implement modal dialogs or confirmation sheets that overlay the main content
• Provide partial reveal patterns where users gradually expand content (peek-a-boo effect)
• Enable gesture-based UI where users swipe to reveal more information
• Customize appearance to match application themes (colors, sizes, rounded corners, animations)
• Handle state transitions programmatically or through user interaction
• Manage focus and overlay behavior in mobile-first applications
