Create

1. Create a new instance using the DataItem constructor.
2. Set the Type string of the instance.
3. Set the Content string of the instance
4. Associate the DataItem with a Field, FormDefinition, or FormSet using the Operations or OtherDataItems property of any of these classes. Alternatively, a DataItem may already be associated with a Field as the Construction property, or with a FormSet as the Identification property.

Write to Persistent Storage

A DataItem is written to persistent storage when the FormSet, FormDefinition, or Field instance it is associated with is written to persistent memory. See FormSet Write and see also FormDefinition Write.

Load from Persistent Storage

A DataItem, stored in persistent storage, is loaded when the FormSet, FormDefinition, or Field it is associated with is loaded from persistent storage. See FormSet Read and see also FormDefinition Read.
