Questions tagged [databound]

The state of (or ability to) being bound to a data source. For example, data-bound controls are user interface controls having the intrinsic ability to display and (in some cases) edit data from a specified data source.

Data binding is a general technique that binds two data/information sources together and maintains synchronization of that data. This is often done with two data/information sources with different types as in XML data binding. However, in UI data binding, data and information objects of the same type are bound together (e.g. C# UI elements to C# objects).
