NET web form control inherits the Data Bind method from its parent Control class, which gives it an inherent capability to bind data to at least one of its properties.
This is known as simple data binding or inline data binding.
Simple data binding involves attaching any collection (item collection) which implements the IEnumerable interface, or the Data Set and Data Table classes to the Data Source property of the control.
