To work efficiently, UI data binding has to address input validation and data type mapping. A bound control is a widget whose value is tied or bound to a field in a recordset (e.g., a column in a row of a table). Changes made to data within the control are automatically saved to the database when the control's exit event triggers.
In this user interface programming technique, the state of one UI control depends on the state of other UI controls. For example, a state-managed UI control such as a button will be in the enabled state when input fields have valid input values, and the button will be in the disabled state when the input fields are empty or have invalid values.
In this example, two text boxes are bound to observable variables on a data model. The "full name" display is bound to a dependent observable, whose value is computed in terms of the observables. When either text box is edited, the "full name" display is automatically updated, with no explicit event handling.
I already noticed one technical issue: if you add default values to the input fields, the output fields don't produce any output until a reader has made an input action to one of the inputs. —David Eppstein 08:30, 15 January 2025 (UTC) That's sort of intentional to try and force people to also set a default value for the output fields.
