suggestion: Consider adding validation for Parent references when using FlatItems
Add validation to ensure all items in FlatItems have proper Parent references before using them to prevent invalid tree structures
Suggested implementation:
if (FlatItems != null)
{
ValidateFlatItemsParentReferences();
_rows = FlatItems;
}
else
{
_rows = Items.ToFlat<TItem>().ToList();
}The implementation assumes:
- TItem has a Parent property of the same type
- The class has a FlatItems property
- You may want to add this validation in other places where FlatItems is set/modified
- You might want to customize the error message or handling based on your requirements
