Understanding Column Metadata

Column metadata defines the schema of a column within a DataTable. It contains structural information needed by both server-side logic and UI components, enabling metadata-driven data processing and dynamic form generation.

Standard Metadata Fields

• Column name
• Data type (.NET type)
• Nullability
• Optional length or precision
• Custom attributes for UI behaviors

Role in UI Generation

Dynamic frameworks such as Blazor use column metadata to generate controls, apply formatting rules, and determine validation behavior without writing static UI code.
