Controls and Data Binding

Controls and Data Binding

What is it?

Text boxes, labels, lists, buttons, and other controls may be bound to fields, calculated, or unbound.

In simple words

• Text boxes, labels, lists, buttons, and other controls may be bound to fields, calculated, or unbound.
• Working method: first identify the input or starting state for controls and data binding; then apply the rule or process in a clear order; finally inspect the output, test an edge case, and explain any limitation.
• Example: apply controls and data binding to a small school, home, or software problem and trace the result.
