Response binds
The external service returns a set of properties using the response mappings defined in the service profile. If the name of a property in the response matches the name of the property that a control is bound to, no response bind is needed. The property is mapped to the correct control automatically. If the property names are not the same, then you must use a response bind to map the property in the response to the bind of the control.
To populate an additional field, add a response bind that maps the desired property to the bind of the control that you want to populate. When the user makes a selection from the AutoComplete suggestion list on the primary field, the additional field will be populated with the corresponding value of the specified property. For example, you may want to automatically populate an ID field when the user selects a name for a Name field.
You define response binds in the AutoComplete configuration. Add a child node to the appropriate node, then add a child node for each response bind.
The Return Property attribute of the node specifies the property that you are mapping to the specified control. The Control ID attribute specifies the bind of the control to which you are mapping this property.
