Before your form will work correctly in the client app, you need to associate each control to a data field that you define, called a binding. This ensures that the data entered into the control is stored in the right place so that data can be correctly processed or actions can be performed using the data. Bindings have a data type associated with them, such as strings, dates, numbers, or whether boolean is set to Yes or No. The type of control used determines which data type is available for the binding. Bindings are created or edited using Forms Designer.

Controls that do not have bindings associated yet display a red binding icon on the Forms Designer canvass. If the control does have a binding, the name of the binding displays in the control properties panel on the right side of the canvass.
