WPF Visual Tree & Logical Tree Patterns

In WPF, element relationships are represented by two tree structures.

1. Core Differences

1.1 Logical Tree

• Structure of elements explicitly declared in XAML
• Based on Content relationships
• Event routing path
• Inherited property (DataContext, FontSize, etc.) propagation path

1.2 Visual Tree

• Includes all elements actually rendered
• Includes elements inside ControlTemplate
• Basis for Hit Testing
• Determines rendering order
