To get a Label control that continuously updates with the current time, you can bind to a property that updates periodically and notifies us using the INotify Property Changed interface.We can do this by creating a timer that updates a Date Time property whenever it ticks.Data binding allows the flow of data between UI elements and data object on user interface.

In two-way binding, the user can modify the data through the user interface and have that data updated in the source.

In above example even if Property A becomes true then text of the textblock will remain "Default Value" instead of "Updated Value".

Fix: In order to work it properly, you need to specify the "Default Value" in style not with the control.

It is also possible to bind, not to a standard data source, but to another element on the page.

Data binding is of two types − one-way data binding and two-way data binding.
