hi

BINDING is basically attachment and passing values from node element to UI elements.

UI Element must be attached (BIND) to node element to get values from.Without node binding Ui element will not be able to populate value.

In other words a UI element which is populating values must be BOUND to a node element.

Basically BIND and BOUND are same.

HI Mandeep Virk,

Thanks for the input.

You meant to say we can use the BIND to bind the value of component controller or view controller with UI node........

yes

We can bind values to UI elements in view controller.

As Component controller has no interface so values are not bound to any Ui element but those context node elements can be mapped with context node elemnts of view controller.

suppose you have input field UIElement. It has VALUE property which must be bound to an attribute of context node.

When user enter some value in INPUT FIELD at run time, that value is handled by node only if it is bound to node.

So node must be attached / Bound to Ui element to get or populate values.
