Implementing Backdrop Pages (.NET MAUI)

The Syncfusion SfBackdropPage is a layered page with two surfaces:

• Back Layer — holds actionable/contextual content (navigation menus, filters)
• Front Layer — always visible, holds primary content; slides down to reveal the back layer

The back layer can be revealed/concealed via toolbar icon, touch/swipe, or programmatically.

When to Use This Skill

Use this skill when the user needs to:

• Implement menu-driven navigation with a sliding front layer
• Build filter or search panels that slide in from behind primary content
• Add reveal and conceal animations to a layered page
• Customize backdrop header icons, corner shapes, or reveal height
• Handle BackLayerStateChanged events for state tracking
• Apply the Liquid Glass Effect to backdrop layers
