Using the Binding options, you can build a form that captures data for enterprise infrastructures or use an external data source to populate a form at run time. Set data-binding properties in the Binding tab of the Object palette.Subforms themselves do not capture or display data, but the objects in a subform can. The binding settings of a subform have a direct influence on how nested objects are mapped to data.A subform can be bound to a data group, and the subform’s objects can be bound to data values within that data group. By default, the bindings of the objects in a subform are relative to the subform’s binding.
