Hi everyone,
Requirement: Implement hierarchical (master-detail) add, delete, and edit functionality in RadGridView, with data flow: GridView ↔ DataTable ↔ SQLite Database.
Data Structure: 
Master Table:  MasterDataTable  (e.g., Orders) 
Detail Table:  DetailDataTable  (e.g., Order Items) 
Relationship: One-to-many via foreign key
Tech Stack: 
UI Control: Telerik  RadGridView  (WinForms) 
Data Layer:  DataTable  +  DataRelation  
Database: SQLite
Core Requirements: Looking for a simple, complete example demonstrating:
1. Binding hierarchical data to  RadGridView  (master rows expandable to show details)
2. Two-way synchronization between UI edits and  DataTable  (inserts, updates, deletes)
3. Batch commit changes from  DataTable  back to SQLite database
Any guidance or code samples would be greatly appreciated!
    Thanks in advance!
