5. VIRTUAL_SCROLLING.md - Implementation Choices

🎯 Purpose: Explains why manual virtual scrolling was chosen over existing directives

🤔 Decision Summary:

Instead of using the existing VirtualScrollDirective, we implemented manual virtual scrolling for these reasons:

🎯 Grid-Specific Requirements:

• ✅ Column-based rendering - Complex grid structure with headers
• ✅ Data streaming integration - Coordinate with chunk loading
• ✅ Performance control - Exact DOM element management
• ✅ Template flexibility - Custom cell and header templates
• ✅ Server-side coordination - Seamless integration with backend
