This property applies to two-way data-binding statements made in the template. The conversion is done after extracting the values from the two-way bound template, and before passing the values to the data source for an update or insertion operation.

For example, a user might enter an empty string ("") for a field value when updating or inserting records. Use the TemplateField.ConvertEmptyStringToNull property to specify whether an empty string value is automatically converted to null when the data field is updated in the data source.
