SayPro Data Binding

Instead of attaching code to a control you attach the model to the control and let a smart GUI read and manipulate the data directly. You can also attach Property Changed and Collection Changed events to the model so that changes to the underlying data are reflected in the GUI automatically, and manipulation on the model performed by the GUI can trigger business logic to run. This technique is the most desirable if your model’s data can be retrieved quickly or fit entirely in RAM.Data binding is complemented with conventional event-driven style; like say your address-book controls are bound directly to the underlying Address object, but the "Save" button invokes a classic Event handler that actually persists the data.Data binding is extremely powerful and has been taken to new levels by technologies like Windows Presentation Foundation (WPF). A substantial portion of your program’s behaviour can be declared in data bindings alone. For example: if you have a list-box that is bound to a collection of Customer objects then you can bind the detail view directly to the list-box’s Selected Item property and make the detail view change whenever the selection in the list-box does, no other code required. A perfectly usable viewer program can be built by doing nothing more than filling the model from the database and then passing the whole show over to the GUI. Or like MVC without the C.What it’ll mean for the design of your program is greater emphasis on the model. You’ll either design a model that fits the organization of the GUI, or build adaptors that transform your model into what’s easiest for the GUI to consume. The style is part of a broader concept known as Reactive Programming.Please visit our website at www.saypro.online Email: info@sayro.online Call: + 27 (0) 11 071 1903 Email: info@saypro.online Tel: + 27 11 071 1903 WhatsApp: + 27 84 313 7407.
