Custom validation to prevent duplicate values in the Grid - Inline Editing

[Guilherme de Alvarenga]

Using the Custom Validation how can I allow only records with unique values (there can be no duplicate values in the Grid)

For example:

A grid has columns ID (primary key), description and Price. The Grid cannot allow the insertion of duplicate values in the description field
