DataLink Field

The DataLink Field connects a form directly to a Dataset or Process. Unlike DataSnap, which stores a static snapshot of selected fields, DataLink maintains a live connection. Any updates in the dataset or process are reflected automatically whenever the form loads.

DataLink stores only the ID and Text values (where Text is the display label for the record). This ensures that forms always display the most up-to-date information from the source.

Properties

• Field Title – Display label shown on forms.
• Field ID – Unique identifier used internally and in expressions.
• Data Source – Select records from a Dataset or a Process.
• Filters – Restrict which records are available for selection.
• Validations – Ensure the selected record meets required conditions.

Field Settings

For general options such as Title, ID, Required, and Description, see Basic Field Settings.

Search List

Users can search for records while filling the form. Search results only include fields explicitly enabled for the DataLink. Clicking the plus (+) button will insert the selected record.

Filters

Apply filters to refine the data pulled from the source. For example, filter a customer list by region or status. For details, see Filtering Options.

Validations

DataLink supports the following validation rules:

• Equal To – The selected value must match a specified value, field, or expression.
• Not Equal To – The selected value must not match a specified value, field, or expression.
